Thanks for that info.
Do you have a link for the Misumi / Mitsumi calculation software?

There are others too that are online - you need to know / assume a bunch of stuff (Mass, acceleration, max velocity, lengths) but shouldn't be too hard.
Hi gmoschini,
Have you purchased your BT30 cartridge spindle yet?
I want to upgrade my Sherline ER16 collet spindle to something a little stronger and more convenient. I have been looking at these cheap Chinese Spindles but I have not really found anyone who has given them good feedback.
Definitely interested to hear your experiences.
I'm still a long way off from purchasing a BT30 spindle cartridge, unfortunately.
I have the mill and I have my DMM servos, but I haven't had the opportunity to get them under power yet.
Next step is power for the mill, then seeing about some ballscrews to get the CNC conversion started.

I responded to a thread earlier in another sub forum (I think the ww one).
I'm in a similar phase as yourself, design. One of the things I have noticed, is that it is not worth it to buy anything from China at the moment. The shipping costs are insane, almost 50% of the cost of the retail price of some items. For that cost, you can purchase slightly more expensive but readily available stuff in the US (regardless of who manufactured it, I have been looking at clearpath by Technik, I have no affiliation with them). As far as head stock, the only company I have found that has something reasonably priced, is glockcnc, but their BT30 and iso-20 headstocks are pre order..who knows when they will have them no matter what they say. I hate pre ordering things and paying up front.
I'm going with the epoxy granite route, similar to the video posted above, although I am surprised I never came across it already. I have been follwing this guy. https://www.youtube.com/watch?v=2woA1BxZ7Pg
