[GrizHFMinimill] Re: $50 mini-mill power feed

I agree the 3/8 shaft is overkill. I'm using the same motor I think. It hasn't arrived yet. But, on your mounting plate, what if you didn't cut the angle on the lower right as you look at the end of the motor? Then you could bolt another chunk of plate on from the outside, drill it, and run the shaft through there. The fork is going to have to be long enough to mount to the shaft and cross most of the gearbox no matter where it came through the mounting plate.

More about your 3rd idea. If you drill a hole through the front of the table, how will that move the clutch side-to-side? Would you actually be milling a slot in the table?

To be honest, I like what you have now. It's just easy to make any number of mistakes while fabricating that I'm just considering simpler alternatives. I get the "out of the swarf" part. But, I'd just use a screwdriver or something. I'm a hack...

As for your idea, a 3/8 shaft is pretty beefy for the lightweight cam, probably get by with a 1/8" shaft, it takes very little force to engage. I'm also thought about cross drilling the x table to run a engaging shaft through to the front, where the ruler is mounted as long as I miss the ways.

If I go with 3/8 for the plate itself I'd have 3/4" to hold the actuating shaft in alignment which should be fine. That would seem simpler than machining a long bushing with a mounting flange and a really accurate bore and should work great. I have some extra ground 3/8 shaft from another project so it should move smoothly.
