Well, today I decided I needed to go ahead and rig up my swing-arm fretboard radius sanding jig for the Shop Fox sander that was given to me. It started with a 2 hr trip to Lowe's to get:
-- 1/2" black pipe (which they cut into two 24" sections and two 6" sections)
-- 2 floor flanges
-- 1.5" square tubing
-- 1/2"-13 x 36" all-thread
-- two 1/4" x 2.5" eye bolts
-- six 1/2" nuts
-- two 1/2" PVC compression T fittings

Image

First I screwed the 24" pipe into the floor flanges.
Image

And screwed the 6" pipe into the T section of the compression fittings.
Image

In order for the compression fittings to slide onto the 24" section of pipe, I needed to thin the rubber bushings.
Image

Image


And then I put the compression fittings back together and slid them onto the pipe.
Image

Image


Then I drilled 1/4" holes in the 6" sections of pipe.
Image

And inserted the eye bolts.
Image

Image


Then I cut my square tubing to proper length - 24"
Image

And inserted the all-thread with a bolt in either side.
Image

Image


Then I attached everything to a base. I inserted the top of the all-thread into the eye bolts and secured with 1/2" nuts. I still need 2 more, though, so I can have 1 nut on both sides of the eye bolts to lock everything together.

Image

Now I loosen the compression fittings and slide each side to the appropriate radius, then attach the fretboard to the bottom side of the tubing and swing to sand. This should take me about 30 seconds as opposed to 4 hrs. I'm pretty pumped.

When it comes to simplicity, I use 80-grit glued to a piece of 24" dia. fiberglass pipe to give me a 12" radius on my fret boards. I clamp a board in place as a guide for square.
