Woodriver Clamping System

I used these clamps on several tongue and groove table tops and am pleased with the results. There is no twisted wood as the glue dried resulting in a flat surface ready for sanding and finishing.

Very nice clamps, Havn't used them. The clamps seem to be well made and strong.Will respond at a later date.

Great product. Have not used yet but I already want to order another one. I watched a YouTube video on these clamps before ordering and I was impressed.

Ok so far Direction can be miss leading

these things are GREAT for gluing boards. They work EXACTLY as I expected them to.VERY VERY pleased

The bar at the end of the clamp screw and on the tail-piece bent with very little force the first time I used it. Save your money.

It takes some time to set them up properly. Once you get in the rhythm they are so easy to set up.1) finish your wooden strips before assembly. Polyurethane will keep glue from sticking well and if you polish the faces, it will keep packing tape from sticking too well.2) put packing tape on the surfaces before the glue squeezes out and glues your glue-up to the clamp.3) once you fiddle with the clamps a bit they become easy to move into position. Look at the pictures that come with the instructions to know the configuration.4) put some dry silicone on the screw.5) You want extreme pressure? You can put your bessy clamps or bar clamps on after you use these to get everything aligned.Cons.1) smallest glue up 3 7/8"2) smallest thickness must be larger than the blocks, ~ 1/2"3) not as strong as the metal $1500.00 (seven hundred fifty each) metal version.The picture shows how the top and bottom popped the bubbles in the bubble wrap. Even pressure throughout.

I have used similar clamping systems, and this one works very well. I would recommend it.
