I'm new-ish to scrolling, been doing other woodworking projects for a handful of years. I've recently found a source of hardwood and been using it for a few projects. I'm making a few name puzzles out of some 1" thick walnut - this kind of thing: https://www.etsy.com/listing/77413048/wooden-name-puzzle-personalized-gift. I have managed to cut the first one of them out without disaster, but it's taking me hours to get the first 6-letter puzzle sanded. I've used a spindle/belt sander to clean up as much as as was practical. Now I'm adding a small round-over by sanding and filing for small areas like where the pieces connect. My wife asked how other people handle the sanding and I realized I didn't know. Surely there are some techniques that would speed this up? I thought about routing a small roundover but I doubt I could get a bit into the smaller areas. All I can think of is a sanding mop. Any other suggestions for how to be more productive while sanding these letters? Thanks in advance.
