These clamps are awesome. And make glue squeeze cleanup a breeze

My concern with these has been that they seem to concentrate pressure on wherever the lowermost edge is placed on the lining. However, I haven't used them so I may be wrong. Do you feel like you get even pressure on the lining when using them?

Ya know, that might be the case with reversed kerfed lining, a product I really like. This is normal kerfed lining. And the angles work. I can assure you I got even bonding. Better than I ever got before. In the tight spots I used clamps, and I still have my bag of HF clamps.

But these really surprised me.

Don't tell SM or the price will go sky high!

I like binder clamps, I use them for all sorts of things. One concern I have for this application is whether they leave little dents in the sides as sometimes the spring steel used is pretty strong.

Also, are these medium or small size?

I use these on reversed linings with no problems.

The key to even pressure is the thickness of your side and lining together. If the clamp fits tightly at the top then you will get even pressure. Some of the clamps don't fit so well and others do. Get some from different batches. There can be a difference.

I use these and I love em. Perfect fit. Get the small 3/4" size. I have never had problems with denting the sides.

I prefer the jorgensen/pony clamps and aluminum spring clamps . for the dble sides.The spring clamps work better on thin stock and thin lining. e.g . mandolins, ukes, vlns, etc

These are the small size, and they do not leave dents. In fact, I was worried when I first used them thinking they might not be strong enough. But they are fine. One downside might occur if you get glue on them, though I have not seen that (rust). But I will toss them if I do. They are pretty inexpensive.

Thanks for letting me know they work on reverse kerf.

One HUGE advantage of these are their size. They don't get in the way, and I can get in there and clean up the glue squeeze.

I use and like these, too, for non-kerfed lining. I've noticed there's a wide range of spring stiffnesses from the different makers. I've a gross from Staples from a few years ago that are pretty stiff. The ACCOs I have are maybe half as stiff, and can't pull 1/8" non-kerfed lining to the sides without some gaps. Corporate Express is also stiff.

I recommend the clamps from Kevin Ryan's Advanced Shell Technology, one of the OLF sponsors. They are specifically designed for use with Kevin's A4 Krefeld linings, but work just as well with most flat sided linings.
