    Thanks for doing these. You may already know this, but you can get those pipe clamps with a base so they stand up, the Bessey "H" Pipe Clamp - which also helps for turning the crank, because they are now lifted away from the work surface, so you don't have to make sure they're off the edge of your workbench before you start cranking.

    Great video, thanks. Best thing I ever did to my pipe clamps....made pieces of 1/2" Baltic birch about 2"x6" with a oversized hole for the pipe. Stick down far enough to be a foot and allow you to turn the handle and tall enough that if you turn them over, they support the clamps above the work. Attached to the clamp faces with small screws. Mine are so old they don't have the feet, but this changed them from something hateful to a joy to use.

  • @googlesbitch
    @googlesbitch Před 3 lety

    I have used many types of clamp aiding schemes for those pesky pipe clamps and have found the use of a clamp pad/stand feature works best. By using a trapezoid shaped wood pad with a hole drilled in middle for pipe and then two small holes drilled on pipe clamps to secure pads with screws and the self standing upright feature with enough clearance left to allow fingers to turn clamps. An additional feature is to add a leather padded face so clamping pressure will distribute pressure and leather pieces can be purchased in most arts and craft stores as leather remnant pack.

  • @richardnineteenfortyone7542

    before laying the planks on the pipe clam, I sight the end pipes like winding sticks to be sure they are parallel. Also, the end clamps are shimmed up about 1/4" to be sure the planks will not teeter on a middle clamp. My boards usually have some cup, but I take care of that with a belt sander after joining. For bench tops, I laminate "engineered wood" flooring for the top surface. Good enough for a lathe bench top. I wish I had a table saw, but I wouldn't use it very often as most of my shop work is grinding and polishing glass optics for telescopes.

    good content. I have a couple opinions though of the glues. As to the Titebond I vs III. I don't think they are "the same properties" but one is more WP. That is a simplification. There are advantages to type 1. Obviously easier clean up, (yes, the glue is soluble in water, so comes off clothes, brushes can be left in water etc) But it also dries hard, with little creep. Type III DOES creep, considerably! It also dries much more slowly. I use III often, but I use I even more. (and use Hyde glue and Recorcinol also, (A glue that is even better than III for waterproofness) I've used Type I for 40 or more years, and have never had any bond "dissolve or come apart because of failure due to moisture. That said, I wouldn't use it for something that was hanging in a steamy sauna or even a shower area.

    Hi, Rob! Have you considered doing a video on hand plane types - what's used for what and how? I've been learning to do box joints and had to plane a tiny bit of the fingers sticking out but only have a cheap $10 plane. I've been going through tons of videos here, learned to sharpen chisels and plan on buying a hand plane, but with limited funds I can't really afford 4 types in a single purchase. But which one to choose as a first, to start? I could probably sharpen a plane blade by now, but don't really know much else about the types. Thanks for teaching!

    Perfect timing! I'm making a walnut table 72" x 44" out of 6" or 8" 5/4 boards. I've recently acquired a bunch of 4' Bessy's. I plan on using biscuits for alignment and TB III.

    @leehaelters6182 Před 3 lety +1

    Kudos! I love that you show how to center the pressure traveling through the thickness of the stock with shaped cauls. Nobody else mentions this! I rely on centering the screw at the head end of the clamp, though.
    I found a good way to avoid having to split dowels and fuss with several pieces: I use ordinary rectangular stock and cut a quick, shallow double bevel on one edge, giving it a ridge that allows the same centering effect. Goes quickly on the jointer, two passes not even changing the fence, just by eyeball. A trifle longer to use hand plane or tilt the tablesaw, but i keep the sticks long and use them that way.
    This is also very good technique when clamping a carcase!

      @nicolaspillot5789 Před 2 lety +1

      @dk builds sprung joints equalize the pressure in the long run, because end grain looses moisture faster than long grain thus shrink more than the middle section. So while and after drying, the ends will *not* in any way shrink enough to produce a micro gap. I love that technique.

    What was the powder based glue you showed?

    • @joshnicholson3208
      @joshnicholson3208 Před rokem

      One reason for using a sprung joint is if you haven't many clamps, you can use even just one clamp in the middle of the glue up and apply enough pressure at the ends of the board by the time the center of the board closes to produce a tight joint. Also it take the headache out of planing two boards perfectly straight but personally I prefer to use extra clamps rather than introduce tension into the joint.

    Rob - your clamps look like you've had them for decades. They probably didn't make the type I like at the time you got the ones you own but the ones with feet are so much easier to use because they aren't rolling all over the place while you're getting them set up.

    • @RobCosmanWoodworking

      @criswilson1140 Před 3 lety

      You can do it that way if you take the time to ensure that the edges are PERFECTLY aligned. If you are off by a hair in alignment you get a bump and the joint is spoiled. I'm sure that if you did spring joints every day then you could learn to do it, but for me, the setup time to align both boards just takes too much time and it is faster to just do one board at a time.

    Great video! I’ve read that a lot of luthiers (who don’t swear to hide glue) prefer Titebond I over the other varieties since apparently it is a lot less prone to «creep». I can image that it might matter in say a laminated ply banjo rim where the segments are bent and under pressure. But does it really matter for other uses? I have no idea. I like them both but I have limited experience.

Adding Urea extends the working time and I have edge bonded boards for table tops by rubbing the boards together until they grab, self clamping, and no external clamps. I also use Titebond III when the boards are too big to simply rub together. I have never had a glue joint fail in over 40 years.

    Hi Rob: at 04:30 you refer to a powdered glue (do you mean a casein or urea-formaldehyde glue such as Cascamite/Extramite?) and you then mention the importance of adding the powder to the water and not vice versa. Are you sure you mean that? With Cascamite (which has a similar open time of around 20 minutes) I always add water to the powder and a little first to create a thick cream (just like you would making a cup of soup from a packet). This avoids the formation of lumps and the action is fast, adding a little more water to achieve the treacle consistency necessary within a few seconds. I am in fact making a video right now using Cascamite powdered glue, a glue i have been using since the 1960's for canoe building. I made a video called 'Woodworking glues - Cascamite' ten years ago and demonstrate there adding water to the powder, contrary to what is written on the tin! By adding water the consistency also is easier and quicker to regulate! I didn't actually see you mix the glue in your video but I may have missed it.

      @@RobCosmanWoodworking Thanks for not dismissing my comment as a troll this time! You emphatically say in your video never mix the water to the powder and yet don't say why but just dismiss it that you never had success that way, yet your videos are highly explanatory! You may be surprised at just how much easier and quicker it is to mix a thick paste and then thin it with water rather than regulating the correct amount with the powder the other way around. Did your mom ever teach you to make pastry? (Mine wasn't arouind to teach me). The water is added to the flour. If its too thin then you add a little more powder. As guesswork is involved in getting the ratio of water and glue powder right, its almost intuitive to add water to powder. Another myth to make a video about?!!! I feel uncomfortable about linking my videos to another channel (although you have offered to link to my channel) but to demonstrate the ease of mixing go to 1 min 39 on this video: czcams.com/video/0N7LEv2gvLw/video.html

      Have about 6 good screw clamps? Stay with a straight edge joint in 99% of your glue ups. This method relied more on using less clamps than any issue with wood movement. on the ends A spring joint can and will fail if not done correctly. Convexing boards can be a pain to perform correctly. I personalty don't use it except on bread board ends. Proper use of glue, clamping pressure and temperature in your shop especially during winter is key!

    Hi Rob. Question...? I do a lot of edge glue-ups with primed wood because it's easier for me to get most of my materials primed already, as most of my casework gets painted. My question is does the primer affect the glue bond? I've never had an issue or a call back, but just wanted your thoughts if you would be so kind. Thank you!

      It would be overkill, but if you're just a hobbyist that only makes a handful of pieces now and again, then why not! If you've got a specific hand plane for the job of course. Getting both tongue and groove accurate over even the length of Rob's boards there isn't trivial with a hand plane if you're just free handing it. If I'm struggling with it at any stage, I often just put the two pieces together in the vice with top faces (what will be top faces when flat and glued) facing out the away (with their bottom faces against one another) and plane them both at the same time. If I'm off square slightly then it'll be offset on either board.

      A Sprong joint keeps the edges of the boards tight together and from coming to park as there is more pressure on the ends of the board than the middle. Additionally you can get by with one clamp in the middle with the sprung join instead of having to use for five or more clamps

    Wow that half a dowel trick is awesome. I don’t think dowels are too bad. I use a piece of scrap the same thickness as the stock with two or three spaced holes in it as a drill guide to get the spacing matched perfectly. Two holes drilled in it, put it in place on your edge, drill one hole, put a dowel in it to hold your guide in position, drill second hole, take out dowel and move guide block. I don’t glue the dowels themselves since they’re just for alignment. On a really short piece I’d use dividers and a center line instead of the guide. On thin stock I use bamboo bbq skewers.

    If you do glue jobs regularly, make yourself 2 pieces of 2x4 , plane on both sides and parallel. Where you cut half round or triangle notches in, where the pipe clamps can sit in. So if you glue 3 feet boards most of the time, take two pieces of 3 feet long 2x4 and put 4 to 6 notches in them.
