Greetings My Good Thumper -
it has been a bit, I am still playiing with the brass Sharps cartridges you sent me way back ... long time .. blah blah blah.
back on topic, if you cannot find a new cylinder, a fellow showed me how cut off/ drilled out the old one and he turned a new "bushing", cutting new teeth on it! If I find the photos I'll post them. It sounded like a rtick method of rejuvinating the old ratchets!
