Squaring Clamps were originally sold in the Lee Valley stores. I bought some 1/4 inch threaded rods and speed nuts and made my own. They work well, the corners are maple carefully sawn to 90 degrees with a small slot for glue squeezout. Very easy to use.

Jack, elegantly simple. I will be sure to try this myself. Thank you for sharing.

I take it the 1/4” rod is screwed into an undersized hole in the block at its endpoint but goes through a clearence hole in the block next to the speednut. Is this correct?

Nice I made some as well but hate using them takes to long to set up at times. You like yours?

Brit you’re right on with your assessment of how they go together. Ken you’re right, they are cumbersome to use, if you drilled out the speed nuts at a 20 or so degree angle with a slightly over size bit, they would slide up to the clamping point quite easily. Havn’t tried this, but should work. Prairie Fire, very cheap to make. As one LJ says clamps on the cheap. I think they were $30 when available from LV.

Jack, I made this clamp system about five years ago. I made two sizes of maple corners, they work great.I would like to recommend using washers in front of the screw nuts against the wood corners. Thanks for showing.

Yes, they sure look simple…

Just to be clear…
1. The fixed ends… are they drilled & Tapped for the rod to screw into?
2. The flexible end holes are larger so rod can move freely?
3. Those Speed-nuts are easy & FAST to adjust to distance desired?
4. Do you have washers between the wood and the Speed-nuts?
5. All available a BigOrange stores?


Thank you.

Hi Joe,
Question 1.The fixed ends are not drilled and tapped, because the rods are in hard maple, so if you choose the right size drill you can thread it in without tapping. 2. You are correct. 3.correct also. 4. washers i did not use, probably a good idea if you use them frequently. 5. I don’t know The Big Orange Stores where I come from, but you could get everything you need at Home Depot type of store, I would assume.
