Testing blocks in the home shop

[flatford8]

“What test would a typical machine shop perform first, and why?” you have to come up with a way to really clean the inside too......I’m not sure if that should be done before or after the pressure test....does anyone think that cleaning the scale out could expose a crack., post pressure test. Making the test wrong. I used 55# as a test pressure because someone on here said they used 80# and somebody else said 25# was plenty....I went in the middle...Mark
