I have no idea what I might have done with the invoice after this long period of time So bringing them back to the merchant would be an exercise in futility. That's why I'm posting this information on my blog to warn my fellow woodworkers once again to be prudent when shopping for woodworking tools. This first picture will give you an idea of just how much out of line to jaws really are
As you can see in the picture, there's a huge gap under the left jaw which should be parallel with the right jaw.
The next picture is a better idea of the type of clamp I was using.
And finally the last shot shows the brand name of this clamp as it was sold to me from the big-box
I couldn't do anything at all with these clamps and, in desperation,I called my wife and we laid out the frames and glued them. She held one end in place and I held the other and we both stood there like dummies until the glue set. Here's what we were trying to glue up.
Here's another shot of the miters. Not perfect but togther finally!
