Time to attach the braces to the back. I didn't post pics of the process of putting on this back graft... it is a thin strip of spruce that is glued across the center seam, that reinforces that seam. That strip is then sanded to a slight dome, as you see in the picture. Then, based on the template that shows where the braces will go, notches are cut into the graft to make room for the braces to cut across them.
Then the braces are glued to the plate, and clamped in place. Here at the shop, we are using go-bar decks for clamping (in the picture). Essentially, this is a countertop, with a ceiling above it at a certain height, and sticks of springy wood that are bent and pressed in place, so the spring of the wood creates the clamping pressure. It is good for providing even clamping action across something being glued to a flat surface. But those springy pieces are tricky, and until you get the hang of how to apply them, they can sproing out and smack you in the head (like one did for me)... or kick your brace over and leave a nasty gouge in it. Takes some getting used to! I got very frustrated with this part... Russ heard me cursing and came over to help me...
BTW... that fiberboard piece that it is sitting on is a radiused dish... the same radius as the braces are curved to... which ultimately helps to create the radius shape of the back.

ok, the description on the phone did not at all prepare me for how these go-bar things actually look. Now I get why you got whacked by one, though. It's a pretty cool system, though, far better than rows of heavy C or U clamps on that light thin wood.
