I see that part, but I don't see how the sprockets actually attach to the custom versahub, at first I thought the pins that held the planet gears in went all the way through the bolt pattern on the sprocket, but thats not it, so?...
Also, I would recommend these guys for the standoffs between the 2 plates, you can hold them with a wrench which is better than hoping it they don't start spinning after a 1/4 turn of the bolt.
I would also try to include mounting holes for an encoder somewhere, maybe the front face. Remember to think about manufacturing method for the plates, I see the CIM boss is set at 0.750, probably won't fit an actual CIM if you use a water jet...but I have no idea if you're actually planning on making one of these 
Again, very cool. |
Thanks for reminding me to put mounting holes for sprockets; I actually forgot about those. Right now there are only holes for the planet gears.
Hex standoffs sound good too. Usually I would just tighten both sides at once, but I guess that's not possible if it's mounted on a face already.
Usually I use 0.752 for cims, but I guess I got lazy there. Generally a plunge with a 3/4" endmill takes it out to just the right size.
Forgot about encoders, and yeah, I'll probably stick those on the front face. Alternatively I could put the encoder in the back and put the shifting part in the front, but it remains to be seen.
The day when we buy a CNC I'm going to be experimenting so much...
