I'm kornfrooshed. You say you drill and tap and install a set screw. Do you drill an orifice through the set screw? Wouldn't closing it off defeat the purpose? Educate the stupid please. lol
Yes you redrill. The set screw just makes it tunable. If you go too big, just screw another blank in and start over. Sorry for the confusion, I think it but don’t type it.
