Yep! I wish that we could still get things at those prices. :-)

O.K. The manual only shows the one chuck.
I am now most of the way through making the chuck for mine. I
need to make a D-reamer to cut the taper inside the nut, and then I need
to slot the collet, and cut the wrench flats on both. I had to
single-point cut the threads in the nut -- I wish that I had known to
order a 5/16-32 tap while I was ordering the 1/4-32. :-)
And -- I have verified that the arbor nut (and the pulley nuts)
on mine are all 7/16" across flats.
Also -- I have verified that the height range will bring it up
to center height with no problems on my Clausing -- and that I need to
make a T-nut to fit the Clasuing, as the one which is there is too tiny
and has to be inserted rotated to bite at all.

I've got a pair of wheels (which did not come with it) which are
nearly 3" diameter, and which finally defined the ID of the guard.

As do I -- though I may try some other ideas for initial
dressing (mount in the collet before the workpiece goes in, not on the
workpiece), and save the shape shown in the manual for dressing in the
middle of a project.
Again, thanks,
DoN.
