This is a super easy and basically free way to use a cheap pinned scroll saw as a sander for fine work. I had a need to clean up tabs that were left over after cutting out small parts on my CNC. This works extremely well for the time spent making the sander.
The parts needed:
A scroll saw (any old cheap model will work fine)
An old scroll saw blade
Double sided carpet tape
The sandpaper is taped to both sides of the blade. The blade is then just put on the saw.
The video shows the process and results.
Thanks for taking a look!
