If you’ve ever been frustrated trying to smooth out your rough scrollsaw cuts — or other cramped edges — scroll saw sander belts can provide some relief. They’re flexible, cloth-backed sanders that attach to most scroll saws and hug the edge of your cuts, sanding without flattening or gouging wood as rigid-backed abrasives can.
You can easily find both variety packs and single-grit bulk packs, but my advice is to snag a bulk pack so you can try ’em out and then just reorder the grits you use most. A package of four sanders costs a whopping $7 shipped, so giving them a try won’t send you to the poorhouse, either.
Google products wasn’t very helpful in locating sanding belts, but you can find them directly from manufacturers — or through several woodworking vendors, a few of which I’ve linked below.
