There were far nicer lathes made in Essex, Holbrooks in Stratford...

I just wish my C13 had leadscrew reverse on it like its bigger brothers, be more than a match for a Hardinge then! I do have a Cunning Plan, though  :dremel:

I'm rather impressed with the long radius attachment, it'd be even more convenient on a Holbrook with the double cross-slide, the crossfeed nut's independent of the taper attachment so you can still use the crossfeed to put a cut on when taper turning or even combine cross and carriage feeds (giving 45 degrees) with the taper setting for "blunt" tapers - very convenient, even civilised :)

Do you cut the long radii under power or hand feed, ditto the skiving tools?

Both done with power feed . You have to be careful with both the LRA and taper attachment to work in one direction , so as not to make an embarrassingly large cut (don't ask how I know this ;-)).

The cross-slide feed in the skiving videos was less than half the speed it could be (too slow in fact), but I didn't want to burn up the tool while experimenting. (I have since replaced my coolant oil !) . The second tool with a greater attack angle, for the tri-ball handle worked much better than the first, but was harder to grind just right .
