My take on a compound radius jig. I hope to build many guitars with it. It will cut standard radius as well as compound. It is quiet large and makes lots of sawdust.
What a fabulous jig! Would it work with 18mm MDF do you think, given the current price of ANY sort of plywood?! I’d love a link to ‘Michael Oldberg’ too - not sure I have the spelling right as he’s in Sweden and a search of that spelling came up with nothing building related. Cheers
Great idea but my main concern would be if you are doing a compound radius on a smaller length of fretboard, say for an electric guitar, the radius would be out as it's only true at the pivot point. I could be totally wrong but unless you have a method for compensating the gradual change, it will only be correct when using the full length of the jig.
The jig is graduated in inches. You know the start and end radius, subtract one from the other and divide this by the number of graduations, this gives the radius at each mark. So you can move the fret board up or down the jig to get the radii you want. If you only make guitar fret boards this jig could be scaled down. I built it this long in case one of my strange friends want an oversized fret board
