3-D Square Precision Aluminum Clamping Corners

I used to think that some things were so easy to glue-up, that using these nifty clamps wasn’t worth the effort. After using them a few more times, I can’t imagine making a glue-up without them! So often it seems that there is no real good way to hold the clamp, and two pieces to be joined at one time unless you have an extra hand. Now you cannot only clamp everything up using the standard allotment of hands, you can be sure everything is nice and square as well!
