I've got a very study Richmond 5" dividing head that I've converted to
run on the very useful Divisionmaster (designed by Tony Jeffree, sold
by Lester Caine). A 5" dividing head is a hefty lump and the problem
that I've encountered is that if I use the dividing head with a
tailstock to support longer jobs there's very little milling table
left for the workpiece.
I was contemplating converting my 6" rotary table to a stepper drive
and using that as the dividing head with a suitable tailstock. This
will free up about 12" of milling table. If I replaced the dividing
head entirely with a converted rotary table are there any downsides?
Once you have the DivisionMaster you don't need a dividing head. So I don't see
any downside ... only the upside of not miss counting rotations on the dividing
plate. And converting the rotary table is relatively easy ...
