Showing how to use a 3D printed spindle stop to remove a stubborn lathe chuck on an Atlas 10F 10" TH54 lathe machine. This chuck removal spindle stop was designed by @DustinRogersinMO and locks the bull gear to allow the chuck to be turned off.

I have now designed my own version of this with a few design changes, you can find it at

If you do not have a 3D printer, contact me and I will print you one for a nominal fee.
