Almost every clamp in the shop over 12" on this one. It was a pain, even using liquid hide glue. The Old Brown cooled down too much and got stiff which made things difficult to seat. Also, the interior panels were slightly bowed which also made it hard to get the top on and aligned. In the end I got most of the joints closed up, but there are a few points where I couldn't seem to get the needed clamping pressure to close them up.
