I bought these at a garage sale today, and I’m not sure what they are. It looks like they would be used when gluing something like a table top, to hold the glue joints in alignment. Am I close on that? Thanks. -SST

Fitting you found these. They are shopsmith clamps used to keep wide glue-ups flat.

Ok. Now I see they are not shopsmith brand. They are similar though. How wide are they?
What brand?

Tom,

I have a set similar to these and you are correct in your assumption. I had to add my own wood to mine which can be used for various widths of glue-ups based on the size of the wood I use.

The concept behind them to excellent, however, they are a royal pain to use if you don’t have at least six hands. I felt that I needed glue with about a 4-hour open time to get everything lined up right! I hope yours will prove simpler to use than mine (or maybe you will have more patience).

If and when I have a garage sale, mine will probably end up there, too!

I thought they looked familiar. The only markings on them are the letters WSC. There are more end pieces than the wood bars with the notched plastic pieces, but it would be easy to make more, but maybe I’ll wait until I grow a couple more hands. Any one else have any experience using them? Hints/ Tricks?

I also scored 2 sheets of 3/16” birch plywood, 1 of oak, and 1 3/4 sheets of 3/4” oak ply, a fairly recent mix of 65 Wood, American Woodworker, and Woodsmith mags, a large quick release woodworking vise, and a gallon of mineral spirits, all for $20.

And I got there after all the good stuff was gone. Probably a good thing. I don’t need more stuff.

Wow, Tom, you could probably resell your clamps (if you can’t grow a few more hands) and recoup the whole $20! What a steal!

I have a set of shopsmith clamps that are very similar. They work pretty good at keeping 2 boards flat and aligned.
Couple of tricks I have learned.
1) dont try and glue-up more then 2 pieces at a time.
2)I use a couple of sacrificial strips 3/4×1” set the clamps to the correct width with the strips before glue up, insert the strips 1” side-up, now opening is wider and easier to insert the boards to be glued. when in place, turn the strips to the 3/4 and tighten clamps. Remember!! not to much pressure, it will bow the glue-up, apply just enough to hold while glue dries.
3) I have also used then to un-cup a piece, but you have to leave them in for some time.

They might be the wood river ones.. I got a pair for Christmas, but still have yet to open the box. The big selling point is that not only do they clamp from the sides, but tend to keep things aligned as well. If you use them, make sure to put plastic sheeting between the 2×2 pieces and the surface you’re gluing up.
