Todays Project - What did you do today?
f350ca- How in the world did you end the thread like that without cutting a relief down to the minor diameter? Do you have a method to automatically disengage the leadscrew?

He sure does. It's called a Hardinge. Smile

Would you believe just really quick on the half nut handle? 
As Ed said, a Hardinge takes all the skill out of threading. The auto feed stops within 3 thou by their spec, but I've checked it with an indicator and its closer to 1 or 2. The compound even has a lever operated quick retract for the tool. You never release the half nuts, just forward/backward with the direction lever.
That thread was cut at about 600 rpm.
Had to cut a relief after to get allow the female thread to shoulder up.
As said, no skill required, try cutting these internal and externals on a regular lathe, I'd be pulling my hair out.

The recess on the male threads was for an O-ring
Free advice is worth exactly what you payed for it.

Not enough metal projects happening so here's some wood.
A design table for someone, apparently they have back issues and wanted one 42 1/2 inches tall so they don't have to bend over.

Added some walnut inlay for detail.

Just have a water based sanding sealer on it yet. Will get a couple of coats of varnish.
