Fret marker procedure:
1. Tape fret board
2. Mark location
3. Punch center
4. Drill 7/32” hole a hair deeper than 1/2 the diameter of the airsoft bb
5. Remove tape
6. Insert 6mm airsoft BB and pound in with rubber mallet
7. Sand flush and polish with really fine emery board
8. Have tried blue and translucent red, but solid white looked the best

Okay… this is exactly what I need! Awesome, thanks for the post!
A great simple design. Do you use it much?

Looks good. When I made my CBG, i was freaked out freehand cutting the frets. This would make it much less stressful. Great job

Well I just used it on a full set of frets. Worked pretty good. You definitely need the piece of hard wood spacer over the fret when pressing. I made the head on the lever out of a block of carving wood. When I tried with without the spacer the fret would impress in the head. Also the length of the lever arm needs to be a little longer. It’s probable good for someone under 50, but definitely not over 70. If your head stock angles down, you will need some spacers to clear it and keep it level.

Just finishing up my first cgb tenor ukulele – stressed out on the nut and saddle where perfection seems to be demanded. Like the fretting jig – thanks for posting.

This is really interesting. I’ve seen some of these guitars on LJs but haven’t thought much about it. It sounds like there must be a lot of people building these. It must be a whole new little world of woodworking.
