Maybe it’s me??
I purchased one of these yesterday and was so excited to try it out today. It worked great joining two sheets of 3/4 plywood, but then I tried it on 1x2’s. I can not get it to clamp on the 1x2’s at all! After failing at using the clamp for those I resorted to using my regular clamps and didn’t quite get my 1x2’s square and flush. I was so disappointed I looked to see if maybe I bought the wrong size, but there is only one listed so I’m not sure what’s going on.
