Struggling to see how ballscrews could be considered a lot of work...compared to making an ATC spindle a rotating nut mount is a doddle. Please see what I posted here:

Let me cure your struggle for you... How much will you charge me for two of those units - steppers you designed and built.

i was blown away when i first saw what Jonathan did with that rotating nut... very impressed.

No brainer to me rotating ballnut every time at this length.!!

And yes I'm up for a bulk buy ATC if it's 12K rpm area. Would prefer BT40 rather than BT30 has the holders tend to be cheaper(Approx £10 less each holder, 10 tools £100 big saving.) more available and allow larger capacity but I can live with BT30 if need be.!

Ok well lets keep looking then, sorry i dissapeared i was trying to get my sketchup drawing to a little less than 87meg!!! so i could e-mail it and it crashed my machine.... damn software...

Well ive hunted and hunted and 10k is as fast as i can find and to be fair 6k was enough for me so if i settle for 10k i wont be going too far wrong. in fact im not sure i will ever use the extra anyhow, but that will mean the bearings should last a little longer maybe..
