I had an old Skil handheld belt sander that I found for nine dollars at Goodwill a few months back. After taking up space for a few months I decided to adapt it to be a small bench mounted sander.
I designed and printed a bracket and printed some knobs for angle adjustment. Then I designed the belt sander table and cut it out of plywood on the MPCNC. Next I used some short pieces of 2020 profile, a few metric screws with nuts, some wood screws and a couple of t-nuts to tie it all together.
Voila! My unneeded handheld belt sander is now a (hopefully) useful benchtop sander.
STLs and other stuff: I’d be happy to share if anyone wants them. It’s sort of specific to this model of belt sander, so I won’t bother uploading.
