I saw something like this at Rockler yesterday. I already had everything I’d need to build it myself, so that’s what I did. I used a piece of 14 ga unistrut with a strut angle bolted on one end. I cut a piece of steel wide enough to fit inside the channel and tapped a 1/2-13 hole at one end. I used a piece of 1/2” allthread with locked bolts at one end.

It probably isn’t strong enough to clamp a cutting board together, but it’ll work great for picture frames and other things I’ll tackle.

Neat Mark. You’ll need a power source to turn the nuts to bring it up the rod fast.

Nice set of clamps. Like Wayne, I would be interested in hearing how well they work for you.

You might be surprised how much you can clamp. It had to be cheaper than the door clamp. I’ve thought about making some kind of door clamp but haven’t gotten around to it. Thanks for sharing. I’m sure it will speed up what ever I do.

I got the strut from a construction supply place. Electric supply places have it as do most big orange or blue stores.

Now if I could only figure out how to build a jointer….

There are plans for one (jointer) in the Shopnotes Tools and Jigs publication. It uses a router for edge jointing. I belive it will joint up to almost 2”.

Great idea for off the shelf hardware. Ive got one very similiar, using the narrow profile unistrut and inlaid level with the top surface four struts tit tat toe style across my four foot by four foot laminated 2×4 glue up table. Then used midified pipe clamps by attaching four hole angle brackets to each then using unistrut nuts to attach the clamps they slide into place then lock down with unistrut nut and bolt. The whole table surface is level to work on. Its adaptable to any situation. Unistrut clamps could be made diagonal (like a panel saw) for those with limited space.

Lowe’s and Home Depot both carry Uni Strut. It’s called/brand Super Strut and can be found in the conduit racks.
