How to Clamp Irregular Chairs

"So there we are. We're fortunate this time because this chair is still sitting flat, but if you get into a situation where your chair is not sitting flat, excuse me a sec, I'm going to grab another longer clamp. If one of the legs is lifted up like say for instance this leg was up off the ground and wasn't wanting to sit flat. What you can do is put the clamp in the opposite side across like this and pull these legs in. We don't have to do it this time, but this is how you'd do it, you clamp this just a little bit and see if it moves that leg. If it doesn't move that leg, then do the opposite. Put the clamp across the bottom on this side. One of those two should work. And then of course, you can always wreck your shop while you're doing this. You can go around it and tap it a little bit. Let the clamp fall off, don't worry about it. Tap it around 'till its pretty flat."
