Ron,
I presume that engaging the back gear without releasing the normal drive
still has too much backlash?
As an alternative, can you make an expanding device to grip inside the
spindle - like the sort of thing people make for winding the chuck round by
hand? There may be a chance to put an arm on it at the changewheel end and
lock that to something.

Subject: [modeleng] Locking a lathe spindle
Calling all Myford owners....
Does anyone have any good ideas for positively locking the spindle, while I
carry out a slotting operation? The Super 7 comes with a spindle lock of
course, but this only locks in one position, and in any case there is a
small amount of backlash with the lock engaged. What I am thinking of is
some sort of friction device, which can effectively hold the spindle in any
position.
Anybody been there before?
Regards
Ron
