Heres a picture of my first lathe projects. The plugs are for the rear hydraulic remotes on a john deere 2010, I found one of the original ones on the tractor so I copied it.
The 1/2" rod I threaded to 11tpi, I couldn't figure out why the nut wouldn't screw on. Then I seen 1/2" bolts are 13tpi so I threaded the other side.
