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 wish these things could be made $2.00.... After looking around and playing with the my FEA model it looks like 4140 would work just as well if that helps.
It's a spindle for a bicycle pedal, and the standard thread for bike pedals is 9/16" x 20 for some reason... The 1/16" hole through the center is for a very small wiring harness and I know it's going to be a pain to drill.
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.
