guitar_player Posted September 22, 2008 Report Share Posted September 22, 2008 I've been thinking about slotting my own fingerboards since I do the neck and body I'd like to do the fingerboard too but I don't know how I'd radius them. I've seen the 8 inch radius sanding blocks is that all I'd need? Quote Link to comment Share on other sites More sharing options...

Acousticraft Posted September 23, 2008 Report Share Posted September 23, 2008 (edited) Recently I made up a radiused sanding bobbin to go in my drill press. I turned it out of a 60mm steel bar on a lathe but I cant see why a piece of hardwood wouldnt work just as well with a bolt for a shank thru the centre. I used an off cut from a Stew mac 12" radius fretboard for a pattern to machine and file it to. I glued some 80 grit paper on and set up a back guide and push it thru on a slow speed with lots of light cuts until I have a full radius. Works great and a couple of swipes with the 12" radius block with some fine sandpaper smooths it out nicely. I will never need to buy any more fingerboards now which saves money on a build.

bluesy Posted September 23, 2008 Report Share Posted September 23, 2008 hey... im not that good in imperial units, can anyone tell me how much is that in degrees?? It's not. 12" is 12 inches - a distance of about 305mm, and it's the radius of the curve. Quote Link to comment Share on other sites More sharing options...
Tristan Posted September 24, 2008 Report Share Posted September 24, 2008 hey... im not that good in imperial units, can anyone tell me how much is that in degrees?? It's not. 12" is 12 inches - a distance of about 305mm, and it's the radius of the curve. Yeah so if you drew out a 24 inch diameter circle the radius would be 12 inches. http://en.wikipedia.org/wiki/Image:CIRCLE_1.svg take one section of the outline of the circle and you've got what the fretboard looks like, a curved line. hope that helps explain the radius a little better for you.
