Woodworking Clamping Tip:
One thing I always notice when clamping wood is you never have enough clamps and you can always use a third hand.
To solve my third hand problem I use woodworking jigs to help out: I call them clamping blocks.
When clamping face frames or boxes that meet at ninety degrees I often use a clamp block assembly jig to keep things square and prevent racking.
These jigs resemble a framing square, can be clamped easier than a square and work especially well keeping larger face frames aligned.
The inside corner was cut a forty-five degrees to ease the inside of corners and not cause issues with the face frame or glue squeeze out.










Rockler just started selling a plastic version of this called the Clamp-It. However I like the price of your version much better.
