Watch This BEFORE Buying Panel Clamps!! There's a Better Way to Glue Up Panels!

[@keithpantermoller328]

Made mine, worked great. One small modification, I drilled and tapped 2 screws into the bottom bar to hole the F clamp in place. Helps me hold them with one hand. I can send you a picture if you want, but Yt won’t let me post one. Thanks again

[@vokinn72]

Dude. The endless "expensive" clamps that you need to own. I've subbed and this is the first video of yours I've seen. Cutting costs is ALWAYS the main goal without compomising results. Thanks for ths video mate much appreciated!

[@vaughnbrubaker4828]

This is absolutely the best idea I have seen for gluing panels and I've watched a lot 'paneel gluing' videos. Always been a problem ... till now. Thanks for taking time to share.

[@martinulloa696]

After watching your video, I went out and purchased four clamps from Harbor Freight. I already had square tubings so I just had to cut slots for the clamps to slide in. I have WoodPecker ClampZilas and Rocklers' variation and you version is so much easier to use. Thanks for sharing.

[@scottsteele8895]

I watched your video and liked the application. I did go a slightly different way and bought Super Strut and now I can glue multiple panels together at the same time. Thank You

[@hanshartung179]

This is a great idea. I'm going to get me some and some of those square tubing and make a set for myself. Since I have so many clamps, I used sketchup and took a 24" section of 2x4, and I drilled 3/4" holes along the 3 1/2" side all the way through. The holes are spaced about 1 1/2" apart, and I put a French Cleat on the back side, and now I can take and put my clamp shanks into the holes and hang them on the wall of my garage. I also made the same thing to hold screwdrivers and assorted things that can fit into the holes. This way one does not have to build special clamp hangers. Now for the large clamps with the wide clamp shanks, I am still working on something to hang those with.

[@lindareiman2345]

Thank you! I was going to buy a couple of panel clamps when I got home that would have cost me $100.00 each. Now I have money saved for some exotic wood. Thanks again.

[@ragman357]

thanks for the information. I have been looking at panel clamps just like yours. i already was questioning the clamps but had no idea they were so weak. The good thing for me is that i already have alot of harbor freight bar clamps and 7 full 20 ft sticks of 1" square tube at my shop. I have been working on ideas to make a small jig to make flags and now i think i have a great design worked out due to your video. Thank you very much

[@petermcquillen6892]

Fantastic idea. I bought 4 10” sticks of 1”x1” square tubing and cut 4 pairs of 2’ and 3’ pieces. The only difference, I cut the notch and the slot for the head of the clamp on each piece. So all pieces are the same. Don’t have to think about grabbing a top piece and a bottom piece.

[@michael.schuler]

Good idea. Thank you. Since you glue up a lot of panels, it might be worth your while to make up a matching pair of support boards as long as the longest panels you normally work with, providing 1" square notches every 6" or so o.c. to position the bottom tubes in place with their top edges flush with the top of your bottom pipe clamps. You could have all these in place in advance, then set the corresponding cauls over them and insert the 6" clamps into the ends as you proceed to apply flattening pressure. These support boards could also have notches to position the bottom pipe clamps. Seems like it would make the process even smoother, requiring less rushing to get everything together before the open time runs out. I love solutions like yours that get the most out of the tools and other investments already paid for and sitting ready to use in our shops.

[@michaels3972]

Great idea! My tip: If you have a friendly local machine shop, you can usually ask them to purchase 1" DOM (drawn over mandrel - that's what makes 'em straight) tubing from their local metals supplier. A 20' piece will make three 40" sets - 6 pieces (minus the saw kerfs) and you should get the price down to about half of the big box stores. Always offer to pay for the tubing in advance - that way they will be sure you will come back to pick them up when they arrive.

[@kirbyspencer538]

Isn't DOM for circular tube (pipe) only. Not sure I've seen that applied to square tubing. Not that circular wouldn't work, it might be as good or better. I'm guessing that all other things being equal, square tubing is stiffer than pipe.

[@kennyb4871]

@@kirbyspencer538 Actually, typically a circle is better structurally than a square. That being said, creating a "Line" contact with Pipe is often desirable if looking into kinematic return, however, we aren't worried about kinematics here, and I would be afraid putting a line divet all the way across with round Pipe

I just watched your video and was amazed. with your clamp concept. I built myself six sets of clamps using your design. I purchased 1" square steel tubing, from a local metal fabrication shop, and had the tubes cut into three of my most used lengths. I had the shop weld a Berger 6" F -Style welding clamp inside one end of all the bottom tubes and cut a small slit in all top tubes to accommodate the Berger clamps. Berger welding clamps bottom leg will fit into the 1" tube without having a slit cut into it. I wrapped all my 1" tubes along with all pipe clamps tubes with Tuck tape. (HVAC Foil Tape) _

Very solid idea. Great design. LOVE the simplicity and practical approach. I've built one Chess board and two cutting boards. Each time, using in the vicinity of a gazillion clamps to get them true. Worked, but man, I was a one legged man in a butt-kicking contest trying to get everything true before I had solid glue.... I'm older, and hopefully smarter. Think I will look very closely into the design you have outlined here.

[@soupofpossibilities8537]

I'd suggest clamping the ends first to get the panel flat, then go back and clamp in the middle, apply the pipe clamps last. Another idea instead of the square tube is to use electrician's channel strut. It's cheaper - $20 for 10' section. It's bigger, so stiffer, and has holes that might be handy to use some nuts & all-thread instead of clamps.

[@BlessedLaymanNC]

I have been thinking about the square tubes, but didn't think of the clamps being over the wood. That's a great idea. Here is what I was (am) thinking. I used one square tube on bottom of the panel. Then, a bolt goes through two additional tubes with a nut as a spacer. The two are set vertically above the base tube and the panel so all three tubes are vertically aligned. Tighten the bottom tube snug tight, but not really tight like you do when you are squeezing the boards for the glue. Then, if there are uneven boards, hammer a wedge over them until they are flat. I see that you clamped the tubes over the boards, which should prevent the bowing as I might expect if you bolted two tubes on the ends just past the boards. So, I was quite surprised by the fact that you said some of the boards were not flat. I know you were proving a point by using only two clamps, so would the non-flat areas have been flat if you had used more than two flat clamps?

[@davidhawley1132]

Buck McDaniel To prevent bowing of the tubes from being clamped past the end of the panel, maybe add on each end another bolt with nuts *between* the two bars as a spacer.

[@jeffbustos6324]

What is the name of the glue release agent that you mentioned?

[@pawpawstew]

Thisnis funny. I'm just coming from viewng another guy's panel clamp solution wherein he drills a bunch of holes in round conduit. Granted, his solution is cool and it works, but I'm sitting here thinking he should have just used square perforated stock. Then I come over here and you're using the same stuff I'm thinking about. I hadn't thought about adapting them to use 6" clamps, but this works much better than using bolts and nuts to clamp the top and bottom rails together. Well done. Thanks for posting.

[@MsLorisM]

I glued up a coffee table top, but hadn't added the breadboard ends, then life got in the way and the project was put on hold. By the time I got back to it, the glued up panel had bowed. I made myself some of your handy dandy cauls and gently forced the panel back to flat. It took about three days in a humid shop. Each day I squeezed it just a little bit until it was where it needed to be. I kept the pressure on the panel until the breadboards were in place. Thanks. One word of caution. The "F" clamps sold at Rural King failed with this system. Bessy clamps held like a charm. The square tubing took all the force without any deviation.

[@howardhagadorn9443]

I bought a set of the kind woodcraft sells where you mount hardware to 2x material. They have a hinged apparatus at the end with the screw for the clamping pressure. What a pain in the ass to get them aligned. I resawed boards to glue up for flat panel doors and didn't realize in the process of planing it flat after the resaw I had taken them under the half inch minimum this system will allow. I saved one panel by using shims under the caul, but had to cut and reglue the other. I had thought of using a homemade system like yours, didn't think of the clamps inside the tubes tho, but it was quicker to buy a premade system that turned out to be crap....... live and learn.

Great idea! The tubing comes in 1”x2” as well then you wouldn’t need to notch it. You could also pair two pieces of tubing and drill holes along the length every inch or two ( drill both pieces at the same time),add a couple of dowels through the nearest fitting holes too your work, then tighten them with a set of apposing wedges. You wouldn’t need the pipe clamps. You could notch the bars as you did your top bar too make the set up easier. Yours do a great job; just a suggestion on how to improve them. Thanks for the great tip!

[@darrellgibson7027]

Instead of cutting holes into square steel tubing, you could just as easily purchase Unistrut. Flip them so that the flat side is against the opposing sides of the panel and tack weld a nut to the inside of one of the Unistrut channels at a few holes to accommodate the most frequently used sizes of your panels. One with the nut and one without would form a pair. Then simply run a bolt through the two on each side of the panel and tighten with a cordless drill fitted with a nut driver bit or socket for the bolt. The wedges would work well to apply pressure to the panel laterally...or you could use pipe or bar clamps like he does

So why wouldn’t you leave the “RB” panel clamps on the whole board until dry? It would take a few extra clamps - but I would have thought that you’d want any vertical movement controlled. Like the idea, keep them coming.

[@ragcell]

I agree. When the pipe clamps are squeezed tight, there is still an opportunity for slippage: something I have learned from experience. Glue just acts as a lubricant. But a great idea, especially for larger gluing projects! I glue lots of smaller blocks together and use 4 angle metal bars (Al (aluminum), in my case, because they are short, less than a foot). The angled bars set on all corners of my blocks really keep all the blocks aligned. I then squeeze the crap out of my blocks along the horizontal plane. I also use kraft paper from my 12"-wide double stick tape (where one side of the paper is absolutely glue resistant; wax paper will also work, but not as well) to keep the glue from sticking to my Al angle bars and my pipe-like clamps. Essentially, two Al angle bars rest on my pipe-like clamps, I then place my glued blocks (two pieces of ¾" MDF, about 4" x 6") on top of the Al bars. Then I put two more Al angle bars on the "top" corners of the blocks and hold everything down to keep them aligned. I squeeze the pipe-like clamps and then use two long clamps to squeeze all the blocks together. I am gluing these blocks on all six sides: top and bottom and longitudinally. All my blocks come out perfectly matched together.

I work for a custom furniture company that loves doing things the hard way, and hates investing in new solutions. Large panel glue ups are one of my biggest frustrations. We make our own cambered cauls that can work well, but we dont have the time to make them to a bunch of custom lengths, and centers of the cauls must be in the center of your glue up. I like this solution it's cheap. If the company I work for is too cheap to invest in a better panel clamping system than our 30 year old pony pipe clamps that are bent out of shape and some jergesons, I'm willing to go buy some square tubing and cut nothes in them if it saves me the headaches! Thanks for putting this out there!
