I need to make the R8 arbor on the left, look like the VN one on the right  Chin
I'll make a new drawbar to suit the 7/16 thread in the R8 rather than messing around trying to cut threads to suit the VN one.

   

I don't have a taper turning attachment for the lathe, so its going to have to be the compound slide. I specifically bought a cheap arbor in the hope that it would be reasonably soft and able to be turned, as I also don't have a toolpost grinder...
This one is hard-ish when checked with a file, but a quick test looks like HSS tooling will work OK (alas no carbide lathe tools yet).

Its giving me a bit of a head-scratch as to how to do it though.
Thinking to modify the taper first, with the parallel portion of the arbor in the 4-jaw, and a center in the collet taper.
Then turn it around, chuck some round stock and true it up then put a collet in the arbor and clamp it on. Use a center in the other end and turn the parallel diameter to size.

Any better suggestions for those of you with more experience?

Steve
