But overall, the ports on the engine are spaced such that the average spacing across the 4 cylinders is 74mm, which is rather handy given that the CBR600RR ITBs have a consistent spacing of.....74mm across all 4 ports. If you do the math, that means each inlet in a Siamesed pair requires a 4.5mm offset.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">I went with this hooky solution because it was the best I could do back then. These were made by clamping some thick wall aluminium pipe eccentrically by 2.25mm in the 4 jaw, then machining each end (manually). Ideally, the porting would be flowed to avoid sudden discontinuities. I had imagined that I would do this manually at some later date using a hand held burr.</span></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjv-Yh2UCnZ2Sm2ICTYWNR_wFq7Lbm9-TTKn4nzzcr611vhmBlZGZKMOMvgONcQMIQkuNmTRhhidghfcGfraQcodr0BXFYeExfm19NbXJCOD9S1A2HLpxRc-dyAyLWiCHuYbmQCEfYwIkYI7H8n7pO3To29_3r2oW2kreUMcPo2fWOuwc2XKmCknC48QboK/s4000/20231231_182352.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjv-Yh2UCnZ2Sm2ICTYWNR_wFq7Lbm9-TTKn4nzzcr611vhmBlZGZKMOMvgONcQMIQkuNmTRhhidghfcGfraQcodr0BXFYeExfm19NbXJCOD9S1A2HLpxRc-dyAyLWiCHuYbmQCEfYwIkYI7H8n7pO3To29_3r2oW2kreUMcPo2fWOuwc2XKmCknC48QboK/s320/20231231_182352.jpg" width="320" /></span></a></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEidhCoMjB52O_376ObpVShIMCoEjmbcWrCtllW5ekHR8b9zJMeEtiGf53nl9F6tZHsOWKPMXULrzF_po6ZR9Jm8VE8LB_gL4Wb4NndEAxRNp7nhR8rzlTKEBw1zRsg8psIYalriU5anDGr4d3FxleqjB3Nk7P6qkEYVsrpuhWnSpEw-eUKP-qdR3PeFJBjl/s4000/20231231_182358.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEidhCoMjB52O_376ObpVShIMCoEjmbcWrCtllW5ekHR8b9zJMeEtiGf53nl9F6tZHsOWKPMXULrzF_po6ZR9Jm8VE8LB_gL4Wb4NndEAxRNp7nhR8rzlTKEBw1zRsg8psIYalriU5anDGr4d3FxleqjB3Nk7P6qkEYVsrpuhWnSpEw-eUKP-qdR3PeFJBjl/s320/20231231_182358.jpg" width="320" /></span></a></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">The inlet ports are somewhat less than free flowing with those steps at the transitions:</span></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgGhFsjLWvI0OsyZnKzodO1mWgSBWc04Q7NrTscpgur3cH5iKTck_ftqKiDnwzgGNu8WxOdhANEH1an9iiWwQsZYafCgDsfAhij-o13fBY6pEfGllEwVbEwv6voNtd3Kq7TP-Yltt4i88hVve4UjpUnZpnFcmBizbZ_zR1dj7dWd8pWteFniP8kctkPfxx6/s4000/20231231_182428.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgGhFsjLWvI0OsyZnKzodO1mWgSBWc04Q7NrTscpgur3cH5iKTck_ftqKiDnwzgGNu8WxOdhANEH1an9iiWwQsZYafCgDsfAhij-o13fBY6pEfGllEwVbEwv6voNtd3Kq7TP-Yltt4i88hVve4UjpUnZpnFcmBizbZ_zR1dj7dWd8pWteFniP8kctkPfxx6/s320/20231231_182428.jpg" width="320" /></span></a></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">Here's what I plan instead. The rubber adaptors are looking a bit perished after 46 years, so it may be rather foolish to design around them. Instead, I will mount my new adaptors direct to the water cooled inlet manifold. This means the mounting surface could see ~100C which is a bit hot for most 3D printed materials. However, the solution may simply be to make a heat insulator plate from Acetal / PEEK or similar.

I seem to have fallen foul of the latter. </span></div><div><span style="font-family: verdana;"><br /></span></div><div><b><u><span style="font-family: verdana;">Conclusions:</span></u></b></div><div><span style="font-family: verdana;">For now, I will conclude that these scanners are good for scanning smallish, organic shapes eg broken handles, hooks, housings etc, thus avoiding having to fully design stuff in CAD. For larger components such as my throttle body assembly, I will be better off sticking to conventional CAD. Must say, I'm somewhat less than surprised at this finding.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">Certainly, I'm clearly not going to be able to create a meaningful engine and throttle body model that I can sensibly manipulate within Fusion 360, so for now the scanner will go back in its box while I stick to CAD.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">Not vastly surprised or disappointed but it's good to have some clarity as to whet this is good for.

It worked pretty well, allowing wireless control of the machine and a reasonable user interface. </span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">For some reason (although nobody knows why), I subsequently bought an "upgrade"(?) kit from another supplier called <a href="https://www.tinyfab.xyz/">TinyfabXYZ</a> comprising <a href="https://www.tinyfab.xyz/cpu-support">a replacement CPU board</a>, some actual limit (micro)switches and <a href="https://www.tinyfab.xyz/lcd-support">an LCD display with thumbwheel input</a>.

Setting the Z height is a PITA - it really needs a proximity switch but for now that would have to wait. I also struggled to figure out how to set up the G54 coordinates ie where Z0 is, where X0Y0 is etc, with the result that when I tried to run a job, it tried to exceed the axis limits. The documentation is "limited" to say the least, so I'd need to experiment (fuck about) with the machine to figure it out.

Also fucking frustrating, which I recall is one of the reasons I bought the Tinyfab kit. On the upside, they continue to support and update it to some degree, as they are still producing new printer models. Having said that, I'm not seeing any significant improvement in terms of the parameters you can access and control, such as the wall thickness, acceleration etc. And the nozzle preheat / filament loading controls are shit.</span></li><li><span style="font-family: verdana;">The Tinyfab kit is also pretty frustrating, although the ability to control settings via Fusion 360 may be its redemption. I may need to look more closely at that.</span></li><li><span style="font-family: verdana;">Loading g code to the Tinyfab via the micro SD card is another PITA, as the slot is difficult to access and you can lose the card inside the display housing if you don't stick it into the socket correctly. There is an ESP32 (wifi) unit on the CPU board, so it should be possible to load wirelessly. I forget if I managed to suss that out.</span></li><li><span style="font-family: verdana;">Tinyfab don't seem to have followed up since I acquired their kit 4-5 years ago. The support forum is almost nonexistent and the technical documentation is rudimentary to say the least. That's not encouraging.</span></li><li><span style="font-family: verdana;">The machine envelope is actually pretty tiny, at 180 x 180 x 180mm. That's fine for small components but for anything else, it's a bit of a toy.</span></li></ul><span style="font-family: verdana;">That will do for now....</span></div>Muzzerhttp://www.blogger.com/profile/13990281947311778449noreply@blogger.com0tag:blogger.com,1999:blog-5456766135104988210.post-86095733324898998012023-12-10T16:27:00.005+00:002023-12-11T17:16:24.666+00:00Finish machining the adaptor mating surfaces in position<p><span style="font-family: verdana;">With the spindle nose adaptor now finally in place and a wonderfully good fit on the spindle nose itself, I have the final(ish) task of finish machining the taper nose that will mate with the various D1-3 chucks.</span></p><p><span style="font-family: verdana;">As measured previously, I have a small amount of radial and axial runout to deal with. The taper is slightly oversize (by design) and I have a few tens of microns to remove. But this could go horribly wrong if I play my cards wrong.</span></p><p><span style="font-family: verdana;">Given that it's a taper I need to finish, there's no manual (MDI or MPG) operation I can use. So it looks as if some hand coded or conversational g-code is called for. I'm not aware of any simple way to gear the X axis to any Z axis moves - doubtless I could do this in LinuxCNC but probably not in Centroid.</span></p><p><span style="font-family: verdana;">Here's the section view, showing the taper dimensions:</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuuBBNfvgbWRI5vJhIQQUDZkb3dmj0dOq2oqLA3x8QlQY2WbYm2LoxFKQ7kmyThf0rI6SOcNgq9YnG-TQzPPW-CqoWLaRqj0_tYJku3BkCb1ZBkh2Y4HzWgsSWhIIlG_Ot5OmEA_I2f_otUipfTpVZjm_MDRG2iBKXhdQGzPrSF5sBCgHXxcFgN4riMHA3/s1325/Taper%20nose%202D%20drawing.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="633" data-original-width="1325" height="298" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuuBBNfvgbWRI5vJhIQQUDZkb3dmj0dOq2oqLA3x8QlQY2WbYm2LoxFKQ7kmyThf0rI6SOcNgq9YnG-TQzPPW-CqoWLaRqj0_tYJku3BkCb1ZBkh2Y4HzWgsSWhIIlG_Ot5OmEA_I2f_otUipfTpVZjm_MDRG2iBKXhdQGzPrSF5sBCgHXxcFgN4riMHA3/w623-h298/Taper%20nose%202D%20drawing.png" width="623" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div></div><span style="font-family: verdana;">The required operation is G90 (turning and taper turning), with the taper radius parameter specified:</span><p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg-js2ry_tmXxrZUa6QPESSXI8W7RMQooEhKgfdTHBC0AVBVNg7iwno_76HNMydDKme4AErXLaLVLTeVVnf_aYGRvDoHdQ87uo-J0HC0OVXNEYuj6w0QFAuZy-oFE42_WS8ufyr1jcLtnJMbQAxBbSxYav9OooPazwS_fE4hMzB9ePu-LuBUPD50t3wngXt/s755/G90_1.png" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="755" data-original-width="577" height="736" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg-js2ry_tmXxrZUa6QPESSXI8W7RMQooEhKgfdTHBC0AVBVNg7iwno_76HNMydDKme4AErXLaLVLTeVVnf_aYGRvDoHdQ87uo-J0HC0OVXNEYuj6w0QFAuZy-oFE42_WS8ufyr1jcLtnJMbQAxBbSxYav9OooPazwS_fE4hMzB9ePu-LuBUPD50t3wngXt/w565-h736/G90_1.png" width="565" /></span></a></div><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjK-yaFjsmw1hVW6yygFuj0rKTy6L5v45kb4yrMfT7pj21eegZ-cJ1m4XzwhpDYwfEr7mh1Nlam_rPtcbPm5dmXbNiwhCWXc8pCjoP4n1l_9pN5RvvdTl69CGW9tjrb3V32d3sLLQQv5hqC3aSlJY_NppFK067ebsaeFq7xjxT-ffGNCy_nLuXwjGqnYxF9/s575/G90_2.png" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="461" data-original-width="575" height="451" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjK-yaFjsmw1hVW6yygFuj0rKTy6L5v45kb4yrMfT7pj21eegZ-cJ1m4XzwhpDYwfEr7mh1Nlam_rPtcbPm5dmXbNiwhCWXc8pCjoP4n1l_9pN5RvvdTl69CGW9tjrb3V32d3sLLQQv5hqC3aSlJY_NppFK067ebsaeFq7xjxT-ffGNCy_nLuXwjGqnYxF9/w562-h451/G90_2.png" width="562" /></span></a></div><span style="font-family: verdana;"><div>In my case, the "R" coordinate is going to be (negative) 2.75mm, bearing in mind that I will be working in units of diameter.

The axial and radial distances are defined by the initial position and the final position.</span></p><p><span style="font-family: verdana;">If you want a taper, the "R" parameter results in an interpolated radial movement as the tool makes the first axial move in Z, followed by the secondary radial feed move. So in my case, there is an 11mm axial move combined with a 2.75mm radial move, which results in a taper of 1.375mm in 11mm (the arctan of 1.375/11 is 7.125 degrees). Note that this radial move needs to be specified as a negative value here. In my case there is no secondary radial feed move, as the start/finish position is at the same radial position as the end of the axial / taper move. It simply makes a taper cut and then returns to the start position.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzZNuYvn1Vesmt4pJlqFeA5CYTTSrp_yPAIZSuesp-7GFvAh_M88tua1h3FQSpdmUCbC25ZC05RocbSHhGpSeASZ5s-s-deqTKXAIcYEcR4_uSA18gHkjPnVoCPuw9i1mpyaD4rwVvJ4GCiArGOU6NqLsWtTAYArdl8GCz9IUQEfPcpQ6nml5n1v1VtZ7Y/s1068/taper%20nose%20angle.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="629" data-original-width="1068" height="351" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzZNuYvn1Vesmt4pJlqFeA5CYTTSrp_yPAIZSuesp-7GFvAh_M88tua1h3FQSpdmUCbC25ZC05RocbSHhGpSeASZ5s-s-deqTKXAIcYEcR4_uSA18gHkjPnVoCPuw9i1mpyaD4rwVvJ4GCiArGOU6NqLsWtTAYArdl8GCz9IUQEfPcpQ6nml5n1v1VtZ7Y/w597-h351/taper%20nose%20angle.png" width="597" /></a></div><p><span style="font-family: verdana;">This is what the Centroid simulator sees when I load this code:</span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7tva34OKSun1kn5gkeCvI88iSfue2cy-dfEAeBrIEQ7oGK8nTEek8hqJpKat1sO4NcCP3Pf9hvV7klV1diJvdTdTb6EJpWPIwvSEyArr14RmWE1wyGpph8V38OT6kyoEUoymnAJqrewpwwtSCGe04VTx4RCVRTlXhWdC87Ouc6Zh3lL3uvA70oZduKD3Y/s1370/taper%20nose%20g%20code%20test.png" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="933" data-original-width="1370" height="392" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7tva34OKSun1kn5gkeCvI88iSfue2cy-dfEAeBrIEQ7oGK8nTEek8hqJpKat1sO4NcCP3Pf9hvV7klV1diJvdTdTb6EJpWPIwvSEyArr14RmWE1wyGpph8V38OT6kyoEUoymnAJqrewpwwtSCGe04VTx4RCVRTlXhWdC87Ouc6Zh3lL3uvA70oZduKD3Y/w575-h392/taper%20nose%20g%20code%20test.png" width="575" /></span></a></div><p><span style="font-family: verdana;">Looks pretty reasonable to me.</span></p><p><span style="font-family: verdana;">I can't stop it beginning life at 0,0 unless I'm missing something here. So I will ignore the rapid move through the stock(!). Apart from that, the start coordinate (X54 Z11) looks right and the end of the feed move (X54 Z0) also looks good. The final rapid move back to the start coordinate (X54 Z11) appears to be as authorised. Looks good to me. </span></p><p><span style="font-family: verdana;">So the plan is to set Z0 at the very front of the adaptor (having skimmed it for axial runout), position the tool around X54 Z11 and hit go. I will start out at a larger radius and adjust the tool wear in X until it skims the taper. Then keep adjusting the tool wear until I have the correct fit.</span></p><p><span style="font-family: verdana;">Let's see how this goes.....</span></p></div>Muzzerhttp://www.blogger.com/profile/13990281947311778449noreply@blogger.com0tag:blogger.com,1999:blog-5456766135104988210.post-90608126180002002362023-12-09T18:53:00.001+00:002023-12-11T16:24:49.085+00:00Boring out the spindle nose adaptor<p><span style="font-family: verdana;">Lots of distractions since the last post due to business trips (Korea, N Ireland etc), family, birthdays, dog, bathroom update etc etc. Finally got some workshop time last weekend and made a start on rectifying the cockup on the spindle nose adaptor. I needed to deepen the tapered bore by around 1.5mm to avoid the adaptor bottoming out on the spindle nose taper which seems to be longer than the ISO spec suggests it should be. </span></p><p><span style="font-family: verdana;">I'm suspected that the Tree spindle nose dates from a period when the ISO spec was either in its infancy or hadn't been defined, given that the Tree was made in the early 1980s and the ISO spec was published in 2009. These tapers were US inventions, from what I can tell. Certainly, the Tree spindle nose includes imperial threads which again are not shown in the ISO version - but perhaps that shouldn't be a surprise.</span></p><p><span style="font-family: verdana;">Anyway, here's the 4-jaw chuck removed from the spindle and the adaptor fitted. </span></p><div class="separator" style="clear: both;

The aim is to allow me to reuse all the D1-3 spindle tooling I have accumulated over the years for the Colchester Bantam on my Tree CNC lathe which has a different (A2-5) taper nose. This will mean I won't need to spend squillions on acquiring all manner of chucks etc for the Tree. This is my design for a "D1-3 to A2-5" adaptor. I've made most of the components now and am keen to get this wrapped up and in use before the sun freezes over.</span></p><p><span style="font-family: verdana;">Previously, <a href="https://www.blogger.com/blog/post/edit/5456766135104988210/6434913208263890039">I made and hardened the cam pieces for the D1-3 adaptor</a> Having made the body and cam pieces, I must surely be approaching the point of completion for this particular project. </span></p><p><span style="font-family: verdana;">Where are we? This looks like the sequence of outstanding actions:</span></p><p></p><ul style="text-align: left;"><li><span style="font-family: verdana;">Drill and tap the holes for the cam retainers. </span></li><li><span style="font-family: verdana;">Machine up the cam retainer screws. These are M8 grub screws, machined down to a ~2mm nose - they mate with slots in the cam pieces. I will use a mild threadlock adhesive to hold them in position.</span></li><li><span style="font-family: verdana;">Mount the adaptor on the Tree's spindle nose and machine the D1-3 taper to final size in position. IIRC, I left it marginally oversize.</span></li><li><span style="font-family: verdana;">Clean it up, finally fit the cam retainers and consider it job done.</span></li></ul><p><span style="font-family: verdana;">The scheme looks like this. I've opted to fit the modified grubscrews from the front face, so that I can remove the cam pieces without needing to dismantle the adaptor from the machine spindle, rather than follow the original plan to screw them in from the rear.

This allows you to set up the workpiece without needing to worry about aligning it perfectly with the table. For this, you need to use existing features on the workpiece - in this case, I can pick up from 2 of the mounting holes using a couple of drills and a precision parallel. The drills are a nice fit in their holes.

To be any good, these would need to be reasonably strong, with the risk of dissolving the test piece if left in too long and also the possibility of some remaining if not fully neutralised. </span></p><p><span style="font-family: verdana;">Or, if not going the strong acid route, there's the use of "chelating" agents. These combine with metal ions and take them out of solution. They are often used to absorb and remove toxic metal salts from (medical) patients or materials without the use of strong acids. There are many to choose from - <a href="https://www.garagejournal.com/forum/attachments/gb2535131b-deruster-patent-pdf.1946829/">this interesting patent shows some of the ones in common use</a>.</span></p><p><span style="font-family: verdana;">Put it down to my Scottish blood or my Yorkshire upbringing but I bridle at paying through the nose for rust removers and I don't want to rely on strong acids for rust removal. </span></p><p><span style="font-family: verdana;">As often seems to be the case, when you look more closely at the formulation of some of these US-originated products, they turn out to be pretty mundane. In the case of Evapo-Rust, they make a big song and dance about their special formulation and even claim to have a patent - but when you search for said patent, none is forthcoming. It's all a big mirage and I'd bet in the end they concluded they wouldn't be able to get a patent granted and/or it simply wouldn't be worth the cost and effort. </span></p><p><span style="font-family: verdana;">The US and EU MSDS datasheets are allowed to hide the chemical makeup of the product - they talk of "trade secrets" but funnily enough, </span><a href="https://www.garagejournal.com/forum/threads/generic-rust-removal-solution.69793/" style="font-family: verdana;">the Australian MSDS seems to give the game away</a><span style="font-family: verdana;">. However, as the market leaders, they have good presence and momentum, so clearly the lack of an actual patent shouldn't actually be a major concern to them.</span></p><p><span style="font-family: verdana;">Either way, it shouldn't be a major challenge to come up with a reasonably effective pH neutral rust remover of my own. There are various examples to learn from, such as discussed in <a href="https://www.garagejournal.com/forum/threads/generic-rust-removal-solution.69793/">the Garage Journal forum</a>, which links to <a href="https://www.youtube.com/watch?v=f9kBdJQMPPI&t=565s">this YT video</a> </span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-family: verdana;"><iframe allowfullscreen="" class="BLOG_video_class" height="266" src="https://www.youtube.com/embed/f9kBdJQMPPI" width="320" youtube-src-id="f9kBdJQMPPI"></iframe></span></div><span style="font-family: verdana;"><br /></span><div style="text-align: left;"><span style="font-family: verdana;"><b><u>What's the plan, Fatty?</u></b></span></div><div style="text-align: left;"><span style="font-family: verdana;"><br /></span></div><div style="text-align: left;"><span style="font-family: verdana;">Let's get some raw ingredients, starting with <a href="https://en.wikipedia.org/wiki/Tetrasodium_EDTA">Tetrasodium EDTA</a> which is <a href="https://mistralni.co.uk/products/edta-na4-ethylenediaminetetraacetic-acid-tetra-sod?_pos=2&_sid=4edcb033d&_ss=r&_fid=aa3327289&variant=213251435">available at £22/kg inc vat</a><br />and some <a href="https://en.wikipedia.org/wiki/Sodium_gluconate">sodium gluconate</a> which is <a href="https://mistralni.co.uk/products/sodium-gluconate-grg?_pos=1&_sid=9e9f1b625&_ss=r">available at £18/kg inc vat</a>.<br />If I use 5% of each, that works out at ~£1.10 per litre for EDTA and £0.90 per litre for sodium gluconate ie £2 per litre. <a href="https://www.amazon.co.uk/dp/B07JKTCZBR/ref=pe_27063361_485629781_TE_item">Evapo-rust costs £35 for 5 litres</a> ie £7 per litre.</span></div><p><span style="font-family: verdana;">How about this for a test piece? </span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjwYDOsInr0PY7xwszz1edAP8FZWb6sdpQ1vGqDODzQAt0TS7-xBPj0k1evLCSsUB9DD3P0QWjHrrsmwz8Rdf4mPQzHDJe5uF9tTU6PNqsC2xMNfD8FF53S-1q2FLIjIb0RLN2YxCw0-W5qGod1-B2_ioK94qHNREycV89o7xyjzOB110YD-sQiW9FmHV-2/s4000/20230923_130423.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjwYDOsInr0PY7xwszz1edAP8FZWb6sdpQ1vGqDODzQAt0TS7-xBPj0k1evLCSsUB9DD3P0QWjHrrsmwz8Rdf4mPQzHDJe5uF9tTU6PNqsC2xMNfD8FF53S-1q2FLIjIb0RLN2YxCw0-W5qGod1-B2_ioK94qHNREycV89o7xyjzOB110YD-sQiW9FmHV-2/s320/20230923_130423.jpg" width="320" /></span></a></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">It's got a lot of dust and loose rust but I reckon this will require more than a wire brush to clean up.</span></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgBiFaOxc1WMIIWI2EzdE4t2fHpaDKBT4FHaoPxQcCOzTTiA08-pao3eMEfdJNtt0mcVLwkNCDMEzJi48198E0KspAr3NW2GGzCVC98V4hDVhvP6O9EZ6Z8eO2SbzLTOuXMLWG6x2r1lx_PbV7O1dyHLJm-TrVl09G2xmrXY0WxCUAd1TYFC3tWcegX4yeD/s4000/20230923_134050.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgBiFaOxc1WMIIWI2EzdE4t2fHpaDKBT4FHaoPxQcCOzTTiA08-pao3eMEfdJNtt0mcVLwkNCDMEzJi48198E0KspAr3NW2GGzCVC98V4hDVhvP6O9EZ6Z8eO2SbzLTOuXMLWG6x2r1lx_PbV7O1dyHLJm-TrVl09G2xmrXY0WxCUAd1TYFC3tWcegX4yeD/s320/20230923_134050.jpg" width="320" /></span></a></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhokeBnezF1H_n1uRooyr7gd52nuNs2vnnTV39vmAeRW5hM38A0Zdv5FHCcbBIk5VNTfmN5z8lhWIQl-eW2QpovRjwgG8ejUQVMYC3jAqEqeM3MS3J91cpu4ufAhFvzE92kF3VNvxaFvtbarsGPBbsqPolyGE_1Y2-nguErw3v1qMMtJ5SCZQq_5r4kC5LE/s4000/20230923_134057.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhokeBnezF1H_n1uRooyr7gd52nuNs2vnnTV39vmAeRW5hM38A0Zdv5FHCcbBIk5VNTfmN5z8lhWIQl-eW2QpovRjwgG8ejUQVMYC3jAqEqeM3MS3J91cpu4ufAhFvzE92kF3VNvxaFvtbarsGPBbsqPolyGE_1Y2-nguErw3v1qMMtJ5SCZQq_5r4kC5LE/s320/20230923_134057.jpg" width="320" /></span></a></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">And here's a mild steel faceplate I made over 40 years ago for my first lathe.

The vise handle has some way to go still but now there is clear metal visible in places and the handle now moves freely. After brushing any loose oxide clear with the paint brush, it's gone back in.

Currently 500rpm but it seemed happy when running over 1000rpm - I had no programmed dwell between the 2000rpm turning spindle speed and the lower 500rpm speed used in the subsequent threading operation, yet it seemed to cope fine during the initial phase where the spindle was still decelerating.</span></li><li><span style="font-family: verdana;">Slight increase in diameter of the taper. This is a very shallow taper and although the finished dimension seems close to tolerance, there is little visible clearance between the axial faces of the taper and collet when assembled. So a more finite / visible gap would be reassuring.</span></li><li><span style="font-family: verdana;">Use a VNGT (polished and honed) insert for the roughing and turning operation, to see if I can get a better surface finish. These are often described as being "aluminium cutting" inserts but some are actually specified as also being suitable for medium to light machining of steel. True, they have no coating but buildup and chip welding doesn't seem to be an issue for light cuts.</span></li></ul><div><span style="font-family: verdana;">First attempt - went fine, if you don't mind a thread that looks like a serrated weapon. The threading was very noisy, so this was due to chatter. I had the tailstock supporting the workpiece, so I concluded that my surface speed was the issue. I can't sensibly try to operate at higher speed (often this is the suggestion to get past chatter), so the solution is presumably to reduce to perhaps 1000rpm.</span></div><p></p><div class="separator" style="clear: both;

But there is a slight issue with this cunning stunt. As you can see, the main body has a through bore of about 8mm. That is somewhat larger than the 60 degree centre pip in the Autolock chuck which is responsible for the accurate radial location of the inboard end of the cutter / collet chuck. So the only way around this would be to create yet another adaptor that would sit in the end of that bore, with a centre hole for location. </span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVFLV2TNGfb-GRb7_qOxEOxQGaG50tJP3a2x7skc5r2b81Cmpe_163vBPIyCJp0QIkpZXNW9O7TAKwnC7JyG5mSBtl5RCM9RzWo21JAdjYA1TBHoUaODxw8zvM9ZO9Qq5m43izgkJEdGc4F8RXeCWilQqVSPf0Wx4iZq4F6mh8L8BiRyQbwmjQr7zS54hl/s4000/20230812_224345.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVFLV2TNGfb-GRb7_qOxEOxQGaG50tJP3a2x7skc5r2b81Cmpe_163vBPIyCJp0QIkpZXNW9O7TAKwnC7JyG5mSBtl5RCM9RzWo21JAdjYA1TBHoUaODxw8zvM9ZO9Qq5m43izgkJEdGc4F8RXeCWilQqVSPf0Wx4iZq4F6mh8L8BiRyQbwmjQr7zS54hl/s320/20230812_224345.jpg" width="320" /></span></a></div><div><p><span style="font-family: verdana;">This would be getting rather messy. Not only would I need to bore out that hole (to ensure it is concentric) but I'd also need to make up a mating part with a centre hole. All of those features would have their own tolerances which would stack up in the final assembly. I'm needing something better than 10um total runout at a guess, so this concept doesn't sound as if it would be worth all the buggerage.</span></p><p><b><u><span style="font-family: verdana;">Bingo!</span></u></b></p><p><span style="font-family: verdana;">At this point, I chanced upon <a href="https://www.arceurotrade.co.uk/Catalogue/Collets/ER-Milling-Collet-Chucks-Straight-Shank/ER11-Collet-Chuck-16mm-ShankJT1-Taper">a familiar looking component on the Arc Euro website</a>.

The Autolock collet is clearly a fair bit oversize. It's marked as a metric collet, so clearly the correct size for a 16mm shank. The way it works is that the thread is always 20tpi, with a metric diameter that's the same as the cutter shank. Thus my ER11 adaptor should have a thread of 20tpi x 16mm.</span></div><span style="font-family: verdana;"><br /></span><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsIf_IS89IHs9-d6omPem3_IA-d_WTEjorYLC_bu69fy7Z6hLaRfhusgpOrLBl4m_ulLgpFVBC1R_NwfOFYMXeJ55KijDCz-MeuMxlJfNWJEyuJECjuvIcl66s45v-jtkfG9UBpDnD7T7rnGwnqIfJ1NHjV3Vrm7b7mcwTh3ft1HOTQet2KnI2d43if1V4/s4000/20230804_172630.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsIf_IS89IHs9-d6omPem3_IA-d_WTEjorYLC_bu69fy7Z6hLaRfhusgpOrLBl4m_ulLgpFVBC1R_NwfOFYMXeJ55KijDCz-MeuMxlJfNWJEyuJECjuvIcl66s45v-jtkfG9UBpDnD7T7rnGwnqIfJ1NHjV3Vrm7b7mcwTh3ft1HOTQet2KnI2d43if1V4/s320/20230804_172630.jpg" width="320" /></span></a></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">I don't have any simple means of checking how much runout there is between the adaptor outer diameter and the internal ER11 taper of the collet. However, the Autolock chuck is in good condition and is surely capable of much better runout than 200-250um. I have to conclude that the adaptor is most likely responsible for most of that.</span></div><div><span style="font-family: verdana;"><br /></span></div><span style="font-family: verdana;">The answer as always lies in the internet, ideally in a web store. In this case, <a href="https://www.shop-apt.co.uk/straight-shank-collet-chucks-mini-and-standard-type/straight-shank-collet-chuck-mini-type-for-er16-collets-16mm-dia-shank-100mm-shank-length.html">a straight shank collet chuck with 16mm diameter shank</a>. I may as well go for an ER16 size, as I have more collets in that size and it would give me a greater choice of usable cutter diameters.</span><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">The plan will be to cut the shank down to length, then either thread it directly 20tpi x 16mm or turn it down to a small enough diameter to allow me to bond a 20tpi x 16mm threaded body on the end (if the shank is too hard to single point thread). At least this way, I should be reasonably confident that the collet and shank will have fairly low runout.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">The speeder saga has some distance to run yet....</span></div>Muzzerhttp://www.blogger.com/profile/13990281947311778449noreply@blogger.com0tag:blogger.com,1999:blog-5456766135104988210.post-41538103744590542392023-07-31T13:46:00.004+01:002023-08-04T17:38:24.100+01:00Speeder reassembly<p><span style="font-family: verdana;">The time has come for me to reassemble the speeder.

Then it would be done and dusted, job done. However, I stupidly handed the job over to The Stupid Fat Bloke. I mean, what could possibly go wrong etc.</span></p><p><span style="font-family: verdana;">Firstly, there's a large (M14) grub screw inside the centre bore that protects the internals from stray muck and swarf from getting into the bearings etc. It needs to go in before Fat Boy welds the adaptor in place. But hold on, if I do that, I won't be able to drift the output shaft out if I ever need to disassemble it later.

These devices cause a milling toolholder to run at several times the spindle speed, by means of an epicyclic gear stage. This way you can run small cutters at the correct speed on a large spindle.</span></p><p><span style="font-family: verdana;">In my case, The Shiz is limited to 6-7000rpm (officially 6000rpm but I have set my VFD to 7000rpm). This speeder has an allowable max speed of 12000rpm, so would allow me to double the maximum usable spindle speed.</span></p><p><span style="font-family: verdana;">This one is by an unknown French manufacturer called "PBC" but it seems to be in good running order. The main issue is that the drawbar thread is imperial (presumably 1/2"-13, making this an NMTB40 tool) rather than the metric M16 of an ISO40 machine. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLIWwozwng1kgo2YOJ5pEPW3kmCCqvLkoG5A3T9Zwihpyxb-i8cYT5TumIj_tTUk6_smJ_jbd-S1a2_f7xi9lMQogzJttosVlPhQv2Vqf3GDaKeZF7YmU8LSps9DgOKOP3DcfCvhQg4XZCE7a93EsQXMT0SbK6Nj4xXE9IwAI_HgqibyfDRkpMIfrBofy2/s4000/20230714_170945.jpg" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: verdana;"><img border="0" data-original-height="3000" data-original-width="4000" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgLIWwozwng1kgo2YOJ5pEPW3kmCCqvLkoG5A3T9Zwihpyxb-i8cYT5TumIj_tTUk6_smJ_jbd-S1a2_f7xi9lMQogzJttosVlPhQv2Vqf3GDaKeZF7YmU8LSps9DgOKOP3DcfCvhQg4XZCE7a93EsQXMT0SbK6Nj4xXE9IwAI_HgqibyfDRkpMIfrBofy2/s320/20230714_170945.jpg" width="320" /></span></a></div><span style="font-family: verdana;"><br /><span>I can't find any useful mention of the thing on the internet but beyond understanding how to dismantle it, that's of no consequence.

I'm planning on machining sockets that are 10mm across flats ie will accept the same chuck keys used by the 3 and 4 jaw chucks. </span></p><p><span style="font-family: verdana;">Looking at the (male) keys themselves, there's a half decent radius on the edges, so I can machine the cavities with a sensible sized end mill, namely a 3mm diameter. I'll also want to chamfer the edges of the sockets and the ODs of the bodies.</span></p><p><span style="font-family: verdana;">Rather than plunge / ramp a 3mm end mill into the steel, I'll start off with an 8mm hole, down to the final depth of 7mm. Then rough and finish the square cavity.</span></p><p><span style="font-family: verdana;">I have some nice 8mm carbide end mills that can plunge cut.

I let The Stupid Fat Bloke continue with the 2nd and 3rd cams, so you can guess what happened. On this occasion, he got the 2nd one done then let his success go to his head. The result is that the 3rd part ended up with a 1mm wide shoulder instead of a 3mm wide one.

But before you drill those radial holes, any blind idiot can see that the camlock stud bores are in the wrong place, by exactly 60 degrees. Apart from the fact it doesn't look like the 2D drawing, it's obvious that the fixing holes would clash with any radial cam bores. Dickhead.</span><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">But all is not yet lost, thankfully. The answer is to create another 3 holes for the cam studs, resulting in a total of 6. Three of them will stand as testament to the power of idiocy. These won't be so obvious when the chuck is fitted but the only alternative would be to start again and make another body from stock. Seems the path of least waste that my laziness will appreciate.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">So firstly I will carry out the radial drilling / boring operation in the 4th axis, before replacing the thing in the vise and drilling / boring the additional 3 axial holes.</span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">Initial step will be to (carefully) set up the work for the 3 radial bores.

In this case, I've got couple of tight fitting 12mm end mills and a straight edge.
