I can't seem to get in touch with Evan Webb (webbteca2006@yahoo.com) who used to offer a "Mod Bar" for Gibson three point bridges.

So I'm going to grab a piece of stainless bar stock and try this myself on Granddad's old drill press.
Does anyone have any pictures of one? I need to see one to try and infer the right drill sizes and depths. Thanks! -CountryScience
