Methods of Joining Wood

Video Transcript

"Another way of joining wood is joining it at a 90 degree angle, there's two different ways or that. You can just edge to edge it and another way is to create 45 degree miter. One in this direction and in that direction, and then there will be a seamless connection. I'm now going to glue up my 45 degree edge glued boards. First thing you need to do is apply glue to the miter corners. Next take one of the boards, lay it on its back between two clamps. Then take the other one and place it to where the two miters meet up. Lightly tighten the two clamps. Next slide them to the edge of the table taking two more clamps, clamping underneath the table and to the top edge of your board. Lightly clamp, clamp these down also. Line up your boards where you need them to be. And then tighten each clamp equally. The next joint we'll be gluing up is just a standard edge to edge 90 degree joint. This is very simple to glue up. All you have to do is apply glue to the edges. Go to the edge of one and to the lower side of another. Laying this one on its back and this one on its edge, slide the two together. Align the edges of your boards. And then clamp your clamps to an appropriate pressure. I'm now going to demonstrate how to just do an edge glue. This can be used if you were making a table top. What I'm going to do first is make what's called a cabinet makers triangle. It's just a triangle that you make over top the joint and what this is to do is to when you're gluing it up it's to make sure you're getting proper alignment. What I'll do next is apply glue to the edges. And then same as with the other joints place the boards between the clamps. I'm going to line up my cabinet makers triangle and then apply light pressure. And then recheck the triangle. Make sure the boards are flush. And then leave for the appropriate amount of time. For example these joints should be left probably at least 3 hours before being unclamped and about 6 to 8 hours before you work on any machines."
