I am looking for some string guides or bushings for my Moderne build. I know of one source for exactly what I need. I'm wondering if anyone may have some suggestions on where to get something similar. I am looking for these - They are 1/4" diameter brass with a countersunk hole and a groove for the string. I can't really seem to find anything similar except for the one source. Any tips would be greatly appreciated. Anyone have a mini mill in their garage? Cheers Peter.
