Review on 🔨 AMTOVL Woodworking Cabinets Carpenter: Enhancing Precision and Efficiency in Positioning by Mark Colbert

They are very useful as a leveling aid when clamping, gluing or nailing frames in the joinery. The problem is that they aren't all square. The smaller ones were fairly accurate compared to the small machine square I have in my workshop, but the larger ones showed a lot of errors. Part of the problem was that the coating on the mold was cut incorrectly and the part looked like it was in the mold used to make it. Before using them for gluing, I checked them carefully and corrected any wrong mistakes with a block of sandpaper.
