I read somewhere that you don’t feel the burr (beyond the first grit), but use a scope. I have a problem feeling a burr and probably remove too much metal just trying to get one. I’m older than you and apparently lack the finger sensitivity that others seem to have. I’m ready to try using this scope you recommended. How does the burr look through a scope – have you got pictures or a source for reference? Do you have any other advice for getting a true apex?
