Is it a lever, or a sliding bolt, which acts as a spindle lock?
A photo, or a part number from the manual, or Myford's web site would help no end.

It’s a spindle lock to be used once you have broken the back gear cluster.

Stephen,

As I recall from my time on a Super 7 in the late 50's, it disengages the spindle lock before engaging the back gear.

No doubt you'll get an update shortly.

Enjoy your Myford. I only wish I was younger and had access to one.

Cheers,

Sam

Stephen,

I should have said …

"Disengage (the lever) BEFORE engaging the back gear."

Cheers,

Sam

I think that Martin means "Disengaged" rather than "broken"

Engaging back Gear and having the pulley / Bull wheel fixed to the spindle will lock up everything.

Some folk use this method so that a chuck can be unscrewed, but risk damaging the gears.

Hence the Spindle Lock to avoid such brutal practices.

If a particlar lathe uses screw on chucks but lacks a Spindle Lock, there are less risky ways of unscrewing a firmly stuck chuck.

I think you would have to be a very strong man to strip the back gear when removing a chuck. Probably could sheer the locking pin too!
