Put the main Capps in your freezer over night, and let the block sit in the sun....
Yep... but most dont do that... IF they are lucky they do the work at room temp.. I had a guy teaching me on machining that came from NASA.. it told me that 5* was the limit for there work.. then it went back into a temp controlled room... so that junk took for ever to machine(with a ton of cutting fluid on the part)
