Hi Chris (Long1),

My name is Henk and I live in the Netherlands and new on this forum. Since I encountered the same problem as Chris. I'll post some photos of the spindle and quill. Checked for roundness of the quill and it is within 0,01 mm except for the top of the keyway. There I measure a few hundreds more thickness. Could it be that if someone (I got it second hand) tried to force the quill beyond the 40 mm down movement with extreme force and caused a high point at the end of the keyway?

No not that I can see. Carefully inspected the inside for things that could obstruct the quill and removed the quill lock mechanism. But I'm a beginner in milling so I'm open for all suggestions.

Hello Chris,

I disassembled the quill yesterday because I have the same problem as you have. Somebody suggested that it could be the o-ring getting sticky but that was not the case. I can't imagine the inside bore being scored and I can't see any scoring on the outside of the quill. Without the o-ring the quill enters quite easy the first centimeters and then locks up. Should I try lapping compound I wonder? Not anxious however to try anything that can make things worse.

Did you solve this problem Chris?
