Assembling a Waterfall Table Miter

Description

Live edge and waterfall tables are extremely popular. Making a waterfall table involves mitering the slab, and then gluing the miter together. These are typically large slabs and big miters. And, of course, you’re not make a four-sided frame. You’re making a three-sided U. That means that conventional clamping techniques probably aren’t going to work. This is a great application for cyanoacrylate glue, clamping blocks, and great clamps.

How’s it work?

Clamping blocks are commonly used as a temporary addition, allowing you to clamp wood in a spot you might not otherwise be able to get a clamp. Keeping in mind they’re a temporary addition, we need to be able to get them off later. That’s where the CA glue comes in. It’s plenty strong for what we need to do here, but we’ll be able to easily remove the blocks after the joint is glued up.

Drawing the joint closed

With a well-executed miter it shouldn’t take much to close the joint. A clamp about every 6”-8” should be sufficient. Take it easy as you tighten the clamps, working your way across the miter.

Other tricks

Gluing and clamping wood can be straightforward, or can require some creative shop engineering. Not every situation is the same, so it’s good to have a bag of gluing and clamping tricks and techniques.

Furniture making

It’s very rewarding to make furniture and see it in your own home, or the homes of family and friends. Once your waterfall table is complete, have a look at more furniture making videos that will help you hone your skills.

    The most crucial part is left out … getting those biscuits or dominoes, as you call them … in the mitred edges. Why was it left out of the process?

  2. Alvin Lievsay

    You did not discuss cutting the dominos in the miter. Would you please create a video showing that process.

    If you're in a pinch and don't have CA glue, could you use hot glue instead?

    And you created that large miter how? Beautiful slab btw.

I am so excited about this project. I've got a waterfall table I'm working on and it's ready for the waterfall part, the miter, to get glued together. So up to this point, here's what's cooking. The bottom of this piece and, of course, the bottom of the leg, have been mitered so that, when the joint gets put together, which we're gonna do right now, and the leg folds under, waterfall, look at how the grain is gonna flow from top to leg, top to leg, top to leg. It's gonna be really, really neat. So, cut the miter, got the joinery ready, now to glue it up, couple of tricks to this. This piece is the piece that came out of here when I cut the miter. I then took it to my miter saw and I cut it into individual segments. What happens here, where we're going next is that, when we go to clamp this together , we need clamp blocks on here so we can pull the miter closed. Here's what's gonna happen. Like this. And we're gonna do this with CA glue because, weh, just trust me, we're gonna do this with CA glue, and when we get to the very last step, you're gonna see why CA glue works so well for this. What I'm doing is just taking the corner of the clamp block, holding it a little bit back from the knife-edge of the miter. And then I've got 'em lined up like this because the clamp blocks have to be opposite each other. Little bit of accelerator. Don't go crazy with the accelerator, you don't wanna over-use it 'cause it causes the glue to crystallize. So, light-duty application on the accelerator. And I'm using a medium viscosity CA glue. That spalting is just beautiful, uh? Here's where we're going next. I gotta re-position my stuff, get glue, get the dominoes that are gonna go into the joints, so, in other words, I gotta get stuff, move things around, then we'll come back and start, psht, getting everything put together. That side's ready. Now, on this one, we'll do the mortises and the miter with glue. Now, in the perfect cartoon bubble, this all fits together. Now, one of the things I'm paying attention to before I get too deep on those dominoes is to get the edges aligned here, because it's easy to move now while I'm not fully engaged. It's gonna be harder to move stuff later. All right. Time for clamping. Now, what I'm gonna do is just kinda sneak up on this. Little bit of pressure, little bit of pressure. I'll tell you what, you know, it's a big miter, and when you get to this step, and it closes like this, it's so cool to see. All right, boy that looks good. I'm really happy with that. Now, a good question would be, yeh, I don't really want that feature on top of or on the leg of my table. Once the glue is dry on the miter, we'll come back and I'll show you what we do to deal with those clamping blocks. Easy peasy. Glue's dry, so these guys come off. And then, what to do with these clamp blocks? Here's the thing with CA glue, it's got strength to it, but it doesn't have a lot of shear strength. Shear strength is when sideways pressure is put on something, like this. Kind of incredible, huh? How those blocks can hold so well while we're doing the clamping, but they pop right off when we give 'em that sideways pressure. Last step for this, sanding, and then I can't wait to get finish on, what I think is gonna be, and absolutely beautiful waterfall table.
