I have spent some time playing with Foredom’s belt sander, but I
ended up going with Kate Wolf’s sander.
The Wolf sander has a 1inch wide belt compared to Foredom’s 7mm
wide, or .275 inches.
The Wolf sander is set up with a quick release for attaching to your
flex shaft cable. Foredom’s is attached to a #30 handpiece. Kate’s
sander is sold with a more traditional clamp for attaching to a
bench or table, or it can also be attached to a GRS benchmate using
an optional GRS adaptor. I believe that the Foredom sander is
primarily hand held.
Kate has also done a great job of working with 3M… so there is a
broad range of belts that can perform a multitude of jobs. The
Foredom I believe has 3 grits of belts (100, 180 and 240). There is
also a plastic attachment on the Wolf Sander so that you can attach
a vacuum off the end of the sander to collect your metal.
The Kate Wolf sander is more expensive that the Foredom tool, but I
think that it is much more versatile and might be better suited for
the types of work that you are looking at.
Good luck with your project. You are doing great work in Mexico!
