Review on 📐 ZONGOOL 2 Pack Contour Gauge Profile Tool (5 inch+10 inch) Adjustable Lock - Perfect Duplicator for Irregular Shapes in Welding, Woodworking, and DIY Projects by Bill Maki

My son and I have recently gotten into woodworking and this tool has helped us create more precise dimensions for some complex shaped parts. After the form is created, you can lock it. The pieces move, but firmly, don't hang out, so they won't shift or slip. Dozens of pieces were tightly packed. Simply press the tool against the object you want to measure and the individual parts will lift up and snap into place. Easy to use.
