I need two of these parts. One of the parts should have left hand threads and the other part needs right hand threads. The material is 4130, but a similar alloy will work if it easier to deal with.
I need 10 of these spindles made from 4130 steel.
There is a 9/16" x 20 thread in the drawing, and I need a versions of this part with left and right hand threads, 5 of each.
