Gas struts are a common feature in this retrofit and I'll be doing the same.
I'll be doing overkill on the motors currently looking at options over 400watt, I found a nice package of 750 watt motors.
I'm still undecided about the spindle, some good chinese options come up that inlcude a power drawbar and direct drive motor shaft. and I can easily get bt30 pull studs to fit my MT3 taper (atleast I think, I bought one to try it/check it.)
Hood your little mill that has the arm that swings out and indexes, how did you achieve that? I went looking for the video on youtiube and couldn't find it.
I have thought long and hard about what would be right for me in this shop and there is are 3 things.
Good, repeatable accuracy
Loads of power, for good cuts and no missed steps, encoder feedback etc.
Fast (6000rpm) spindle Power drawbar for quick tool changes.
The ATC etc can wait really, and I can interpolate holes or use an idea i had for spindle on time, dwell, and a tapping head. Probably much cheaper and easier then setting up rigid tapping.
