This is quite a difficult job that I have to do.
Pieces are from a oil pump, and the fit needs to be perfect. I am equipped with a CNC lathe, but I do not think that this piece is meant to be done in a lathe. I need advice on how to machine the piece on the photo. It is about 15 inches long. It works like showed on the picture.
If more info is needed, please let me know.
Any advice would be well received.
