Encoder scale support bracket - que?
Currently, the end of the encoder scale next to the "(axially) floating " bearing bracket is magically supported in thin air. I need to make up a bracket for that. It doesn't need to be massively strong.
The bearing bracket is fastened to the bed by 2 M6 screws. There are also some cross drillings that will be blocked off by those M6 fixings. However, there's a good 6.5mm of steel in those cross bores and they are 5.4mm diameter, so easy to tap out M6. That's more than enough to support the encoder body and although it won't be 100% threaded, it will be pretty strong. So I can hang my bracket off those and avoid having to make any more holes in the machine body.
That should work. Projecting the various holes onto the body from the other components ensures it should fit together out of the box. Like this:
Let's make the thing!
Chop off some 2"x3" stock
Faced off and ready to go
Top side done, now just need to face off the sacrificial base.
Sorted. Yesterday it was just a sketch and extrude component in Fusion. Now it exists.
Not many bits left to make now. Must be about time to start trial assembly...
