I had a stone get jammed tight before I started using a spring, Had to take off the holder and remove the pilot then put the holder back in and tap it back and forth to get it broke loose, tossed out that stone. I start with a smaller size to just knock off the high spots and go bigger till I get what I want. I have made a lot of stones and I have a lot of holders, once you dress a stone you never want to take it back off the holder because you just have to dress the stone away, they get beat up fast enough.
