Default Dangerous chuck mounting? 12" South Bend chuck

Can you put in a spindle lock ?

Something like a C5 threaded tube. Locks by pulling on the inside of
the chuck and on the far end of the spindle a compressing thread, locking it in.

Simply the fact that such mounts are not intended for use with braking

IIRC. Lathes that will swing 20 and 17 inches, respectively, with flat
belt drive and Babbit bearings, about 130 years old.

If you do anything stupid, they will bite you. You either learn to not
do stupid things, or you learn that you need a more modern lathe with a
more idiot-resistant chuck/faceplate mount.


Well, I am glad that on my Clausing, I can use brake, reverse etc and
the chuck will never unscrew itself, due to a keyway.

With a 12" chuck, it is plainly a scary thought to use a lathe if it
has a brake, or an ability to power reverse.
