[QUOTE="DSheetz, post: 1653442, member: 91783"] I know from experience , lapping high pressure safety valves , that if you lap to a high polish the two surfaces will stick together and not be able to release when they should . We would lap to 1200 grit to make sure there were no scratches in either surface then break it back to 600 grit so they would release at 1850 lbs.at 850 deg. F .You can have too much of a good thing . In the last thread on a similar issue it was discussed that the tumbling of brass with S.S. medium would flair the end of the case mouth by letting them hit each other and peening the edge over . So then some of the things I have gathered form reading this site is , don't leave your brass to tumble too long, tumble your S.S. pins by themselves to dull them first , you don't need a highly polished piece of brass just cleaned , use a good lube when sizing your brass then clean the lube off after sizing and loading and chamfer the inside and out side of the case mouth before sizing . Is that what I should have gained from these threads and have missed anything . I am here to learn and it seems there is a lot for me to learn here . [/QUOTE]
