90 Degree Clamping Jig – Shop Tip

90 Degree Clamping Jig

Woodworking Clamp Blocks – Shop 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 a 90 Degree Clamping Jig – shop tip to help me align casework, assist with dry fitting and glue-ups.

Using The 90 Degree Clamping Jig – Shop Tip

Clamping face frames or boxes that meet at ninety degrees I often use a woodworking clamp block assembly jig to keep things square and prevent racking.

This Clamping Jig resembles a framing square, can be clamped easier than a square and work especially well keeping larger face frames aligned. They work perfectly when clamping corners and help a lot when squaring up to face frames or cabinet boxes.


Making The 90 Degree Clamping Jig – Shop Tip

Using a framing square I cut these jigs out of scrap plywood.  A circle cut-out and two smaller square cut-outs facilitate clamping by allowing a place for clamps to grab. It also is a great spot for hanging the clamps on a wall.

The inside corner of this Clamping Jig is cut forty-five degrees to ease pressure on the inside of corners, not cause an issue with slightly misaligned parts,  and not cause issues with the face frame or glue squeeze-out.
