Nice, i need to make a bigger one that can be used as a spindle also, but completly controlled by Linuxcnc.
To many projects, not enough time.

Truth be told that is my plan lol. A C5 to 5" chuck plate...
Would be more for drilling indexed holes for u-joints of leveling heads and such than a 4th axis though.
Not sure it if would be useful or rigid enough to use for milling complex features, maybe flats...

I plan on using a brake for it so when stationary it would be firm. I have 2 disk brakes from a 1000cc Kawasaki that i dismantled a while back, should do the job nicely.

fyi i'm stealing your idea, didn't think about that. Setup a pneumatic switch on the brake... sweet
I got an extra pair of MTB disc brakes i got for a few dollars way back. :)

Feel free, i doubt it is my idea, i can bet my life someone else had that idea before me, just did not bother to check it. From experience of a million ideas in my life time, maybe i can say 10 where original ones, and those where not life changing.
I have a weird gift of thinking how to use things for purposes they where not made, like using 2 satellite dish motors for a motorcycle lift instead of hydraulic jacks, or using car wheel bearings for a heavy duty spindle ( car wheel bearing with holder 20 euros, spindle bearing 800, still working after 2 years of heavy use by a friend of mine ).

For info, I am about to order a batch of castings to hold a Harmonic Drive FHA-25B servo unit.

I can add more to the order, but postage outside of the EU will be expensive. Two are already going to Germany.
