Roy; I don't turn mine
they come right out of the mold like the pictures
but I sure do not know how you can do them so cheap my material cost more than125.00 cnd. $ the best I can do is 200.00 without the time to strip and time removing grease sand blasting so mine work out to250.00 each if they are not clean and ready to do
The ones I redo are done with the same polyurethane that is used in stamping dies that will take approximately 1 to 1 1/2 million hits before destructing under full compression
