Here you will find some fretting jigs: Fretboard Radius Jig, Fret Press / Fret Clamp and Homemade Radius Blocks
They were all made to meet my demands and they do. Maybe you want to make your own in a different way and that's allright because whatever jig you make it should do what you want it to do.
You will find some videos below that will give you an idea on how to build them, if you want to.
I've added some pictures of the latest jig, a slotting miter box, as well. There's no video of this one, yet.
