View Full Version : 5c spindle taper lathes

10-18-2009, 10:05 PM
Is it posible to get a 5c spindle taper on a lathe other than a hardinge hlv or clone. I like the idea of a 5c taper spindle but would like a larger machine...somewhere in the 13 x 40 size. Is it because most machinists like larger spindle diameters. My thoughts are that any 5c collet chuck or nose wont have the inherent accuracy as a 5c spindle. Any thoughts

Buy the lathe that will work for the jobs you do, then add a set thur 5C collet chuck.
just my $0.02

Seems to me that unless all you do is work to very great precision (one or two tenths) that the advantages of a larger spindle bore, easily available chucks, etc, far outweigh any additional run-out caused by a MT-5 -> 5C adaptor.

Just make the adapter IN the lathe....... and mark it for rotational position. Then it will be as accurate as your bearings when put back in that position.

You could find yourself an old Rivett.

Otherwise a spindle nose and a drawbar if your through hole is big enough.

Last resort is a collet chuck.
