Yes I get what your saying and this is my point.! To do it correctly and be worth the trouble it won't be any cheaper I don't think. Custom made anything cost's money.!!

This is my take on it.!! . .The chinese WC spindles in there current format are not really suitable to ATC for both the spindle taper type and the fact they are high speed low torque motors.
To design one based on the current WC spindle will require much trial and error and at £180 pop and quality angular contact bearings etc you don't need to get it wrong many times to start building up the costs.! . . . . If you did manage it then IMO you would still have a less than ideal ATC setup.!

If moneys no object then go for it and I know I'll be watching with great interest.!

If you want an idea of the work involved in building a proper ATC spindle then checkout Henriks thread on cnczone and he still wasn't 100% happy with it when finished because it had 0.01-0.02mm runout.!! . . . He's bit of a perfectionist thou.!
