What do you call those bolts with the small plastic [whatever] plate on top to support the guitar body in picture jig_w.fixture.jpg? I'm building the Vinson jig but that information is not included in the pdf. I need to know what they are called so I can source some in the UK.
This has pretty much been my experience. It really helps with flimsy necks and complicated s-bends. I wouldn't recommend one to someone who hasn't done 20-30 old school fret jobs to develop neck reading skills.
