I made this spindle lock for x2.7, lms 5500, or G0836, looking for any feedback folks might have to offer

Very Cool. I don't have audio so I can't tell if your saying anything or not. Will it be spring loaded to the open position?

It cams enough that you need something to keep it from pushing the pins out and rotating the top. I was thinking of a thumb lever that would lock it open or closed. I don't think i'm going to try to put a spring on the rotation.

Nice work on that mechanism.

If you are not going to have spring to unlock the spindle when you take you hand off then I would definitely add a switch to disable the spindle while lock. When I was building my spindle lock I thought to myself I won't forget and leave the lock on when I try to start the spindle. Well put the switch on anyway and I'll bet a hundred time I've turned the spindle on and when It doesn't come one I look up and the lock is on.

This is what I did. The safety switch is a reed switch stuffed in a hole in the base plate. There is a rare earth magnet mounted in the bottom of the lock ring. I wired it into the enable circuit of the speed control on the mill. When the magnet is over the reed switch the spindle will run.
