How to Use Bowl Turning Paper Joints

I've got a nice piece of maple here that I'm going to turn a bowl out of and I'm going to do that by mounting a face plate to it. Now that has a couple of ramifications, if I put my face plate on here and our drive screws through the face plate into the bowl. Of course, when the bowl is done, I'm going to have screw marks on the bottom of it that’s no good.

Additionally, those screws penetrating through the back of the blank limit how deeply I can cut, really want my chisel to cut wood. I don’t want it to cut screws. So I get a have a different method here. I got to have an alternative technique. One I like to use a lot is to use a dummy board and a paper joint. So this is pretty cool.

Paper joints are not only for ball turning. There are a lot of different applications and other things where you can use them. The bottom-line is that the paper being in the joint allows you to separate it later, so done a couple things here to get ready. I found the center of this blank then I dimple the center with a scratch on. So it’s going to distinct center point.

Now on my dummy board when I cut those, a center point is left here in this disc. So I drove a nail through. So the nail is sticking out the backside just a little bit. I'm going to eventually want to engage that nail into that hole. That’s why it’s projected out like that. That’s about all it takes to get ready. The dummy boards could be cut from anything. This is cut from scrap plywood that I had. So now, glue this surface and glue this surface.

The paper is absolutely low tech. this is just cut out of a brown paper grocery bag. You do want to use paper that’s poorest not shiny, so like a printed page out of a magazine. It wouldn’t work very well for this because that would prevent the glue from soaking into the paper. We need something poorest.

Now that nail found the center of my blank, so that’s all set to go. All I need to do is clamp it. Anytime you're gluing something up for late turning. Your best bed is to leave that sit overnight, so the glue has a good chance with here. The last thing we want is for this to separate while we’re working on it. That’s all set.
