Fretboard Radius Drum Sander

[immortalx]

Hi guys!

This is a fretboard radius drum sander i build some time ago.
It works just like a regular drum sander, the only differences being that the drum itself has a radius and the fretboard blank is guided with a drawer slide. It is constructed from two 20mm plywood boards with hinges on one end, a pair of pillow block bearings and a steel axis on which the drum is attached.
The upper board is raised by a threaded rod located under the lower board. The drum is made of teflon (PTFE) and was turned on the lathe.
By using an aggressive grit (P40) the fretboard is shaped in a matter of minutes and all it needs is some minor hand-sanding with higher grits.
