Hi Cooper one thing when you polish the cylinders you do not want a high polish you need something that will grab the oil so you want smooth not polished.

ID grooving, I found them on McMaster . Oring groovers and snap ring groovers . You have to take them slow and a very good sense of touch , they break easy . Always use tube for your barrels. Manual or cnc , you should be able to do stainless . You could chrome your barrels .
