Hi, Short time lurker, Horologist in training in need of a little help ...
I purchased an emco v-10p at the end of last year, and after a few minor
problems proceded to train up in its use, starting with the milling head,
and im now getting more into the lathe side of things...

I have a 3-jaw 5" chuck (fitted with external jaws) and a 4 jaw independent
and self-centering 6/7" chuck BUT, cannot remove the backplate for the 3 jaw
to use the 4 jaw.. I wouldnt have a problem with this except that i have to
set my tools up strangely to reach into the "Cup" of the chuck.

Pretty much what i would like some help with is either a) how to remove the
backplate, without stuffing the spindle.. theres a couple of holes on the
geared end of the spindle that i tried holding a 1/8th" rod in while turning
the backplate as much as possible (not much to grip) (yes the locking bolt
on the backplate has been undone)

2nd option for the moment is trying to obtain a 2nd set of jaws (internal
stepped) for the 3 jaw chuck, which would be nice regardless... the jaw
width is approximately 3/4" wide, (left my remotely accurate measurey tools
at work)

All advice graciously accepted

Thanks
