Sorry to see that crow. I made a laminated hard maple top about 1.5" thick for woodcarving around 1979. It is showing tiny spots like yours but I don't understand. It has been in a dry basement and I stood the pieces on edge so carving tools would hit slightly harder wood. Lots of hours went into making that. I got lucky and for sanding after laminating the top I had a buddy with a 49" platen driven sander. The belt/platen would go forward at a chosen rate, the thickness was cranked down to a precise thickness. It cost me nothing but the belts that clogged up with old glue. I have used that bench for carving and general gun tinkering ever since. Yes, some airguns have had scope mounts cone there. All kinds of fun. A great project but I don't know where the plans are now. It has a wood vise on one end and one side. I don't have a photo, I'm a dinosaur. Roar. Be Well Brothers, B.
