Depending on your buffing jobs, you might also look for super-cheap
(used will generally get you more for the money) wood lathes, which can
be set up with a long arbor between centers and multiple buffs. Rather
than multiple buffing machines or changing wheels, IF the parts can be
worked without needing a free face to the wheel, you can load up 3-5
buffing wheels and move from one to the next with no time for setup,
other than cleaning the part.

A friend showed my his similar setup using a garage sale vari-speed
wood lathe.
He had various arbors made for all his wheels - grinding, buffing, and
wire.
It was a very slick setup and one I intend to duplicate.

Thinking a bit further about the details: I have a 1"-8 spindle with
MT2 taper. I have two woodworking chucks that fit with the smallest
jaws taking about 0.4". Probably not useful in this application. I
also have a horrible 4-jaw chuck and a base plate. What would be the
best way to attach the arbor to the spindle?

I was thinking a MT2 collet like this:

or even adapt an end-mill holder like this:

for a bigger arbor

running the arbor between a dead and a live centre driving it off the
base plate seems a bit of an overkill.

I suppose I could get one of the cheap chucks like this:

Also, what is the deal with the conical arbors? Is it mainly
convenience and ability to change wheels quickly?
