How much of your woodworking is CNC? I’ve been thinking about selling a slightly different take on fountain pen trays, but I’m just routing by hand and/or with jigs.
After a 20 months of optimizations, its now 80% CNC, 20% sander. There is a specific product that my CNC barfs on 100% of the time, so I have to do a batch of like 30 at once so the failures don't have any real impact. My next big purchase will be a small drum sander ($1500) so that I can leave an onion skin (1/16" - 1/8" thick) on the bottom of my stock and let the sander remove it. But I need a good Christmas season to make that happen.
