    Sorry for late reply, been busy with work. My diy BT30 spindle works great, couldnt be happier. 10h/day for few months now, no serious issues yet. Cut like a butter but the lack of power (2.2kw spindle) is holding me back to cut like a pro. So i am already considering upgrading motor with 3kw spindle or 3x more expensive servo motor with 11Nm ofcl torque.

    Ross77, it is sqeeze release, i have a steel bar to sqeeze the washers. No intention to make it fully automatic, no need for this yet, and a lack of room to place cylinder over the shaft. The spindle shaft is hardened and ground. Here is old vid of the spindle. Runout is approx. 0.002mm, tool holder and collets are from china, thats why such runout in vid, which is still great for my first diy spindle
