I was considering making a small part, like a 1/4" rod maybe 2" or 3" long but with a 1/8" turned down end for adjusting the rod. However, any 1/8" rod will do so do I supply this for the new guitar owner or leave it to them? It's just another dang piece I'll have to make, buff and nickel plate. Might not be so bad I guess. I love maching.Ah, cool! Are you going to use a pin spanner then to tighten it? I didn't expect you'd have room for that.
OR, just cut out a bit of an arch and use a pin punch?
