Brass rod ... it's total overkill, but it's everlasting. A perfect match for a pack of Ben's gold fretwire too.
Thanks everyone for the replies. I have scanned the site looking at all the pics of various dot inlays. They all look so good, so it is hard to choose. I really liked the darker stained ones the best. I am being too much of a perfectionist I think. Anyway, thanks again. D
I've used the hole-punch method to punch nice, round markers out of flatpick material. Get those big Fender triangular picks and you can do a whole guitar...
I used a Forstner bit (1/4") to drill the holes, using my drill press for precise depth. They look good and fit flush.
For the side markers, I use one of those hairbrushes with the thick plastic "bristles" with the little knobs on the end.
These are tapered, so I just cut them off, stick them into a 1/6" (or so) hole with some glue, and then cut them off flush with a razor blade when dry. They look quite professional....
You could use bullet casing ends, that's my favorite. 38 special seems to work the best for when you get down lower on the fretboard on the last few frets. Check out my page cause I couldn't figure out how to link up a picture. I get alot of positive reaction from those who see them used.
