Coolant hose rerouting

The original coolant arrangement was a gooseneck hose, allegedly setable to almost any position. Of course, it's a bit old now and they never quite stay where you need them. But above all, the stupid tap is mounted right at the back of the machine on the vertical face behind the spindle. This means that you have to lean right in close to the spindle to adjust the flow or walk round the side when it is running. Or stop the machine while you adjust the flow and position. 

I bought some JetOn cooling system parts from Cutwel not so long ago and initially I used a short length of flexible 15mm pipe to run the coolant to the front. I supported the pipe with a couple of plastic clips but overall the rigidity was pathetic and there was little to stop the entire hose from swivelling. 

The main JetOn coupling has a 3/4" BSPT thread. I managed to get a brass fitting with a 15mm compression joint on one end and the 3/4" BSPT female on the other. At the other end of the copper pipe, I needed a standard 1/2" BSPT male. Then a length of copper 15mm with a gentle dogleg bend. Finally, a simple bracket to support the front gubbins and stop the couplings from swivelling. Simple enough but still requiring an hour or so of buggerage.



Sorted.

Final assembly and test of the spindle nose adaptor - RESULT!!

After the recent distraction caused by the 3D scanner, resurrecting the 3D printer and buggering about with the throttle bodies for my Honda...
