Peachtree Woodworking Supply 2 Pack of 4 Way Pressure Clamps - Clamping Panels From All Four Directions. For Woodworkers, Cabinet and Furniture Makers

When I opened the box, I was impressed to see how well everything was put together. Easy to install. I do recommend predrilling your before installing the screws. If you have never used this style of clamp, there is a slight learning curve. I like that the cranking portion of the clamp are metal. They are durable and a great value for the money. Easy to align and keep the boards flat with even pressure. There are reviews that this is hard to use, it is not, it is different clamp and does take a little time to set up. You have the ability to choose whatever length clamp you choose. I have a set of 24" and 36" boards that I can easily switch between. I have two sets that are great for when I am making cutting boards. Having equal pressure on all four sides is a must. Do follow the instructions and you too will enjoy these as much as I do.

These helped me step up my glue up game. Super simple to use. Easy to install. I like that they are adjustable for most sizes. Great clamping power as well

I'm waffling between 4 and 5 stars here. These clamps work as designed, are high quality and heavy cast iron and seem like they are made to last. That being said, there's a learning curve to using them effectively. I suggest practicing with them during a dry fitting of your project before adding in glue, otherwise you're likely to make a real mess. Okay let's back up a second. The first thing you need to do is mill 4 lengths of wood to use as the crossbars for these clamps. The instructions are perfectly fine (despite a reviewer here complaining about them), but you need to know how big to make them. I bought these for use making cutting boards that will be no more than 13" wide, so I made them 24". You should also own a jointer to get a good milled edge on the crossbars, so that might be a small challenge if you don't own one. Regarding the learning curve, you need to play around a bit to figure out where the clamps should be positioned on the grooved plastic thingies so that there is enough room to get your glued pieces into place and to give you the right amount of space for clamping. While I have not yet made a cutting board with these, I did use them to glue up a 13' long countertop using various lengths of board that were around 3" wide. I placed the bottom crossbar of the clamps underneath the dry piece, positioned correctly by dry fitting everything first, then glued up my 2nd piece and slid it into place under the top of the clamps. Then, I put the top cross bar into place and clamped them down. From that point on it was easy to put other clamps into place as needed. So, overall, I do think these are very helpful. You could easily get away with two lengths of board or metal to sandwich your board together with regular clamps, so consider these just another option.

Very well-built. For added straight edge, instead of wood beams suggested, I bought a metal 8' square tube 1-1/2" square for each clamp set of two, cut them in half to make two 4' beams, drilled and threaded for 1/4"-20 x 1" flat head Phillips machine screws. For gluing shorter panels, I used a 10" piece of wood (spacer) to reach the clamps bumper pad. This was more expensive than wood (cost of square tube and screws) and heavier, but gives a much straighter edge to hold the wood panels being glued together. It also doesn't stick to the glue and won't warp over time which wood beams would do. Very good product, strong, and offers unlimited options for length. Much less costly than fixed length ones.

These clamps work great. Bit of a learing curve, but once you understand how they work. Its a game changer.. Im not sure about other reviews? but the instructions were clear and very detailed. I DO recomend using a hard wood, (Oak) insted of a 2X4. The pine will "bow" slightly when the clamps are torqued down. I've seen videos where folks shave the ends to make the center a bit more concave to compensate for the bowing effect... So far I've clamped quite a few cutting boards and I have to say I've had no issues..

Took me a little while to come up with a good method to do a multiple piece hardwood glue up for a cutting board. The trick is to get something to hold the top bars up and out of the way while you place the glued parts on top of the bottom cauls. Also a good idea is to use duct tape to surface your cauls so the wood glue won't stick to them. Once I got that figured out I (finally!) produced a nice, even, cutting board glue-up with perfect alignment across the tops of all 16 boards. Next I used it to clamp a panel for a cabinet, which required less thinking to setup. Again, it worked great! These things are now my go-to clamps for these types of applications. My only small concern is the instructions tell you the width to cut wood for the cauls, but I found these to be too tight and made it hard to slip the cauls (covered in duck tape) in between the rungs of the clamps. Next time I shave them down a 1/16th or so from the instructions (but don't go too thin).

Plan ahead with your settings. Superstrut 12 gauge. Use a 5/8 inch dowel to align all the slot on your super strut. Know how to clamp. Don’t overtighten. Works great when you have your panel already dominoed. If you don’t like planning and setting up this isn’t for you. But if you know what you’re doing, this will take your panels to a new level (see photos for ideas that may help). Those are 1/4-20 Allen bolts connecting to 1/4-20 superstrut cone nuts. Adjust accordingly. Rocks!

Looking at the drawings and description, this would seem to be the be-all and end-all system for panel clamping success. If you've got the time, energy and patience, I suppose that this system would be ideal for the purpose. Unfortunately, there are a few things that get in the way of the whole process. There's nothing in the minimal instruction pamphlet that mentions the type of wood to use for the cauls, and there's no mention of cambering the cauls. The first cauls I made were basic 2x4 pine stock, ripped in half lengthwise and sealed with urethane to prevent the glue from adhering to the cauls. I also didn't camber the face of the cauls that faced my project. That was three mistakes on my part. Although the pamphlet suggested ripping a standard 2x4, my experience taught me that you get what you pay for. Unless you've got a few weeks to allow the 2x4's to dry out and acclimate, make sure you get KD (kiln-dried) 2x4's. If you can find 2x3's that are fairly clear and straight, just use those without ripping them in half. They're a little more expensive, but it's well worth the extra price. Choose wood that's as tight-grained as possible. After cutting them, make sure you camber the project side of the cauls, This ensures even clamping all the way across your project. If you're going to use urethane on the cauls, make sure you seal all sides evenly, otherwise your cauls WILL warp. Whether you use urethane or not, either apply a coat of paste wax all around, or use shipping tape along the project side of the caul to prevent the glue from adhering to your project face. Using wax paper or parchment paper between the caul and the project makes sticking even less likely. If you're not going to use a scrap piece of wood to protect the project edges, I suggest applying self-adhesive rubber weatherstripping to the jaw pads. I use a dual "D" profile type of weatherstripping that worked perfectly. I've got a few ideas in mind to reduce the drawbacks of these clamps. Once I've implemented them, I'll append this review.

Work really wellFantastic wish I got some earlier

Das Produkt wurde sehr schnell aus USA geliefert. Alle Einfuhrgebühren waren im Preis enthalten. Eine wirklich durchdachte Konstruktion. Wirkt auf mich sehr solide. Ist gut zu handhaben. Achtung, ohne Änderung der Klemmhölzer ab 15 mm Dicke aufwärts anzuwenden. Besonders für dicke Platten einzusetzen, die sonst Probleme bereiten.

Excellent produit, très robuste.

Works very well

Because the panels are kept flat they are much easier to clean up saving hours of time They are very decent quality and a good investment for any small workshop
