    Great idea, going to make up a set. Thanks for sharing.

    Good idea! I could have used this in my shop today. I struggled with gluing a small frame. Will have to make something similar.

    Lovely idea, but experience has shown that there must be no inside corner, ie there must only be two side at right angles and not joined.

    my only reservation is that might it not be better to drill smaller holes and then jig them as larger perpendicular squares? that way it will be slightly easier and less fidgety when it comes to fitting your clamps and possibly a more even precise pressure can be applied and less chance of slippage as youll be clamping flat rather than on a curve? if that makes sense?

    what a simple yet great idea, well done and Thank you for sharing!

    Corner clamping isn't easy without a special set up. The clamping pressure really ought to be perpendicular to the glued surfaces for greatest effect. Applying masking tape to the outside of the pieces before gluing and "folding" helps a little. There are also spring clamps with sharp points to apply pressure across the joint.

    This tool is especially useful for ensuring the parts are held at a right angle while gluing. Good work, and thanks!

    Don't use white / wood glue. use urethane (aka gorilla glue ) or epoxy , then no pressure on the joint is required, just keep the pieces in place until it sets. :)

    About the glue joint; You are right but most commercial jigs are no better.
