8mm lead screw to the left with cast nut. 7/16-20 lead screw installed. Does much to add rigidity.

This is the next mod for mine Charles. Shows a small Sherline Lathe but prints for a larger one for the 9x20 are available. I have a set. http://downrivertools.com/downriver...d-turret-for-grizzly-9x12-lathe-drawings.html

well out of my comfort zone Bill.
Looks very cool though.
Will this be for all the repetitious work required for the radial engine?
Did you cut the 7/16 20 thread or use all thread? (wash my mouth out with soap and water)

Single pointed left hand thread Charles. That's a long way to run a die and hold tolerance and all threads is junk for this. LOL

The handle is started
then is finished
with a touch of polish.
So far I have used the plinth for threading and parting.
Parting is an absolute joy now, 40mm aluminium not a problem, 10mm stainless, straight through, no grabbing no juddering just clean cutting with long wavy ribbons.
I'm well happy with it.

Oily or dirty hands will change your mind about using that polished ball. LOL

Just thought I would post these to show how it now parts.
There is no way I would ever have contemplated doing this with the standard setup.
Just look at those long ribbons of steel.
Just to bring it back to reality, I didnt start the cut with that much overhang.
And the other part that I wanted.
As it came off before I faced it dead smooth.
Now all I have to do is get the blade exactly vertical with some shims and have another go as it did cut slightly curved.
