That's pretty cool. These can't be bought at hardware store right? I guess they wouldn't have radius of these sizes sitting around. I wan't to have something so I know exaclty the radius that fits my hands. Guitar pros can play on any kind of neck, for now, I need an easy play 12-14 inch to learn on. Would you sell me a set and show how to use these radius parts? This stuff is probably second nature, to me it's rocket science. Lol.
