Review on DEWHEL Positioning Woodworking Carpenter Precision by Juan Huerta

These are wood tension tools so I didn't expect them to be accurate for machinists. But they are so badly made that they ruin the glue in the box. Simply pulling them out of the packaging seemed to me to be clearly doing them wrong. So I trampled her to Bridgeport and... not good. They are only 89°, see attached photos. This is 1/8 inch area per foot. Or for a typical dresser, about 1/2 inch square. There are much better clamp squares here at Revain, including some cheaper ones made out of orange plastic. Don't waste your $ on them.
