I've got a couple of boards I glued together edge to edge here. And I'm going to use this as an opportunity to prove something to people that I'm often asked about, when I'm teaching classes and I have people gluing parts together they always want to add a nail, add a screw and what I tell them is that “Today’s glues are actually stronger than the material that you are gluing together”. And if we gave that glue a chance to dry and fracture the board later, it would actually be the wood that would fracture, not the glue joint. And they're always a little bit incredulous about this so I'm going to show you that it’s true.

These red oak boards were jointed, glued together. I let them sit overnight so the glue would be plenty dry. Now, just to help highlight kind of the before and after I'm going to use a felt tip and I'm going to mark where I can see the seam is right here. All right, there’s our glue line and here’s the fun part I'm going to swing this boards against the corner of our device. Aiming as much as I can right for that glue joint and we’ll see what happens, you ready?

Now, let’s have a look at this, look at the wood fibers remaining on this piece it pulled all of those out of the other piece. So just like I said it was the adjacent piece of wood that fractured here, there’s wood missing from this one. So it's actually the wood on either side of the joint that gave way not the glue joint itself. Proof that the glue that we’re using is stronger than the material you're putting together.
