Hi, I just want to show a jig I have built today. It's a fretboard radiusing jig that uses the router table and works on the swing arm principle. I'm not sure if I saw this somewhere or did I just take ideas from different jigs I've seen.. It still needs some tweaking before it can be used seriously, promising already though. The pics tell most of it: The holes were drilled on the drill press while the pieces were stacked together for a perfect match. There's a flush trim bit on the router, and the bearing rides this tight slot to keep the bit centered. Shown with a test piece of scrap mounted: There are holes for the usual 7.25", 9.5", and upwards in one inch increments from 11" to 20". (EDIT I just realized that the pic doesn't show the holes that are on the frame behind the swinging part - there's of course holes at similar heights as on the swing arm... (/EDIT) This could also be used for different compound radius fb's, just needs some tweaking to make it swing better when the bolts are not in the same holes. Here's a test piece with 9.5" radius. The edge is rough, but it's not the jig's fault. I was mostly worried about the centering but it seems okay. After taking the pics I did better bolts to hold the swing, no pics sorry about that. I'll show some more next time.
