Rob, hard to believe that this topic has only gotten 133 comments over two years, because it is so first principles important! Here is my two cents regarding #3. When clamping a slab, most times ripping to width is done post glue-up. This affords me the opportunity to put a slight double bevel on the outside of an edge board, which is no trick to do lickety split on the jointer, no setting of fence needed. Just two passes on the edge with a slight eyeballed lean gets me a good enough tent shape on the board edge. Back to the clamp-up, the screw end of the clamp almost always has a swiveling foot to allow centering the pressure, and the double bevel on the far end centers pressure with no fumbling of pads. All the best, you are still my hero, Rob!

Funny you mention over tightening... My first job was in a millwork shop and I remember cranking those bar clamps so tight I'd go home with bruises on my palms. After learning more, I've often wondered how strong those glue joints were after I squeezed all the glue out. Would be interesting to test.

@mikemccarthy6127 Год назад

That 45 degree stress clamping spread angle is excellent info for clamp spacing. I'm just learning about actual woodworking as opposed to finish carpentry. A while back I made some winder stair treads by gluing multiple red oak stair treads together with pipe clamps after running the butted edges through a tablesaw (I don't have a jointer). It worked out well but there were a lot of things I think I got lucky on after watching some of your videos. Getting the panels flush at the edges was challenging. That third hand clamp method would have really helped me. For glued panel edges, you or someone mentioned running the adjacent panels with the table-sawed edges flipped so any slight cut angle out-of-squareness would be supplementary. I didn't know that at the time either but must have squared the blade up close enough.

@ricos1497 2 года назад

When I started, I bought a bunch of large Bessey clamps in a sale. I used them when building my first table out of oak and they certainly worked well. However, over the years I've found them increasingly useless due to the fact that they are so heavy and the force they apply too great for anything I'd need. This is largely down to the fact I am much better at planing and generally always being square. My first table was probably squeezed to within an inch of its life, now I just bring the surfaces together like you did in the video. I've still got my Bessey clamps and they're the only thing big enough for the wider glue ups I somtimes do, and it's noticeable how much more stressful they make the process due to their weight. I really must sell them and buy some medium weight clamps instead!

@RobCosmanWoodworking 2 года назад

I compltely understand your journey, as I said I use the squeeze the live out of my glue-ups

@andrewbrown8148 2 года назад

Great tips, Rob~! You're right on about it taking a while to accumulate a decent amount of clamps. I'd be afraid to figure up how much I've spent over the years. And YES, buy good quality clamps~! Also, Black Friday shopping has saved me a lot of money.

@perfectjays 2 года назад

You should do a video with comparing or recommending a face-vise or any vise for a budget, $150.00 and under or something like that! Kinda how you do videos on other plane brands and seeing how they stack up with others! Love your videos by the way! I’ve learned so much from you and the guys, I re watch videos all the time in case I missed something!

@barryomahony4983 2 года назад

12:00 Bands: I rarely have to do just one band; usually it's several on the edge of shelf boards; etc. So I do them in pairs, back to back, with the bands in contact with each other. The clamps then go from the (non-banded) edge of one board to the other board, and the clamping pressure is easily properly distributed to the two joint surfaces.

@RobCosmanWoodworking 2 года назад

Yes that a great tip, I wish I would have mentioned that in the video

@hurcorh 2 года назад

I've been using the 'quick grip' medium duty jorgensen clamps recently. They seem to be quite effective, easy one handed operation when needed. Before that I had a stack of Bessey F clamps but in certain operations especially where I only had one free hand they become a pain to use.

@RobCosmanWoodworking 2 года назад

I really like them for light duty stuff, too

@jumbocaso 2 года назад

Rob, do you ever use parallel clamps say from Bessy or Jet? They seem to work well with panel glue ups.

@deathsyth27 2 года назад

Masking tape works great on sheet goods too like MDF for glueing up miters. We go through multiple boxes of tape every week making parts for our kitchens but it works so well we never found a better way.

@douglaspollock102 2 года назад

I’m new to woodworking. Thank you for sharing your knowledge. I checked the show notes in the description and saw a reference to the store, but there’s no reference to specific tool you used for planing. I do not own a plane yet, but the pencil lead demonstration wants me to give planing a try. If I’m only going to buy one plane, or if I’m going to specifically buy one plane for getting a smooth edge on the board before clamping the glue-up, which brand/model plane do you recommend?

@generationswoodcraft 2 года назад

When I started woodworking I had no idea the strength of glue and didn’t trust it. Even hearing Rob say it’s stronger than the wood itself just didn’t sink in till I used it. That caused me to clamp down till my hands were purple. It the joint is good the glue will do the work with a little pressure.

@RobCosmanWoodworking 2 года назад

Its almost against our nature. we all want to squeeze the life out of that joint

@alandust2188 2 года назад

@woodshopnerdery 2 года назад

Galvanized 1/2 inch pipe for pipe clamps. In my area the galvanized pipe is nearly the same price as the black pipe. The galvanized pipe will not turn your glue squeeze out areas black, and the glue seems a little easier to clean off.

@kellanaldous7092 2 года назад

I've only been woodworking about 3 or 4 years, but I have 4 bessey F clamps and i think 6 of the harbor freight ones, and honestly they work exactly the same as long as you take care of them and provide some lubrication. I don't have bar clamps yet, and when I needed to glue up something larger, I bought a couple of the extruded aluminum bar style clamps as well. These ones I regret buying. Maybe not regret, as they did a job I couldn't have done otherwise, but they're not great. Especially when I make cutting boards, the screw end of the clamp doesnt stay parallel to the bar, when you tighten it down the top leans back which makes the wood want to bow up in the middle. Cauls help, but I really need to get something better lol

@RobCosmanWoodworking 2 года назад

If you want good aluminum bar clamps the ONLY ones to buy are Dubuque Aluminum Bar Clamps, you wont have that problem with them

@happywanderer5632 2 года назад

Rob, how do you clamp thin pieces flat to the bench for cutting rabbets, dados or groves? I have a 3/4" part I'd like to cut a groove in, but the fence of the plane is higher than 3/4". Obviously I need to raise the piece onto a board, but what is your recommendation for doing this so that it clamps securely? There must be a jig or something you use. Thx

@danthechippie4439 2 года назад

Great tips, do you recommend the butterfly joint where you plane both edges at the same time so doesn't matter if you are planning square on the edge to the face?

@whittysworkshop982 2 года назад

That's known as "match planing" 😁 It's a decent technique....... but make sure your plane is long enough to keep the edge straight or itll cause problems. If the bevel on your edges is too great then they can slip and slide in the clamps, cauls will stop this and keep them flush enough 😁

@RobCosmanWoodworking 2 года назад

I have never heard that called a butterfly joint. Typicallt a butterfly jount is using a "Bowtie" shape of wood to join two boards together (normally used for repairs). But no, do not like to match plane, I prefer my edges to be dead straight. I feel my chances of getting a dead flat panel are best with dead square edges

@garthwebster6433 2 года назад

As you mentioned, clamps are expensive. When gluing panels, I like to use a spring-jointed caul. One clamp in the middle of the glue up is all it takes. Now, with your idea, I will rout a round over on each side of my caul to send the force down the middle. Eureeka! Thanks Mr. Cosman.

@RobCosmanWoodworking 2 года назад

When using cauls your method you should realy put a slight hump in the middle of the top and bottom caul so the max pressure in in the muddle of the panel.

@leehaelters6182 6 месяцев назад

@@RobCosmanWoodworking, my take is that Garth is talking about edge pressure with fewer bar clamps.

@artswri 2 года назад

RC tips are nearly always 'this is the best practice'. As in... If you're not using these tips you're not getting the best glueup results. (compared to so many tips from others that are cute or even kinda clever but are typically more for show or for filling out the need to have a video this week rather than being truly useful)

Sight down your bar when you begin to turn the screw, and watch it bend without any hesitation. the feet of "parallel" clamps are never parallel under any pressure whatsoever.

It’s stronger so it doesn’t tear as easily when you’re putting downward pressure on it. You can also use regular tape doubled up. Prep the pieces you need before you start the glue up.

@victorfiore6332 2 года назад

@MMWoodworking 2 года назад

Is there a reason Rob took all of the caps off of the Bessy clamps? Did he just lose them over time, or was it intentional? I'm always worried that the metal could dent the the wood. Also, could Rob do a section of a video some time about how to get squeeze out out of tight corners. I often end up with small little spaces, especially internally, where the interior finish won't take because I couldn't get the squeeze out removed without spreading it, due to the small, tight, generally corner space.

@_cb336 2 года назад

He mentions that the caps can slip. They’re also plastic and minimally compressible, and in some critical clamping situations even that small amount of deflection can be a problem. Cut some thin, soft wood pieces or half dowel and put them under the clamp pads to protect your work. For interior squeeze-out, you can always mask off the joint. It’s a pita, but sometimes you have to do it. If the finish isn’t so critical, the old straw trick works great. Use a plastic drinking straw pushed into the corner and run it along the glue line. The glue ends up in the straw like magic. If you’re not getting all the way into the corner, sharpen the straw to a point, like a quill pen.

@RobCosmanWoodworking 2 года назад

Miles, I mostly dont like the plastic caps that come with the F clamps, I like the more positive grip you get witout them. I take them off but save them as every now and then I run ito a situation where I do want to use them

@CarmoniusFinsnickeri 2 года назад

The way you describe the advantage of using the half dowels seems strange. Yes, you get the force in the center of the board edge, but the angle of the force is not helped by the dowels, if the jaws tilts under pressure, the force will be just as angled as without the dowels. So, the dowels doesn't eliminate the need for altering the clamps. Or?

@RobCosmanWoodworking 2 года назад

Make the piece in the shape of a triangle, force comes from the point, similar concept with the half dowel
