Dear Jack,
I have a tumblast from Wheelabrator that I need to shot peen some small steel parts about three inches long by 3/8" made in the shape of a half-moon.
The parts tumble around in the Tumblast to be peened.
My question: Should I put the Alman block and test strip in for "x" amount of minutes to test it or should I use a different method?
Thank you,
Mark
