Quoted from robotron911:
Just an FYI from one of the pics in this post. You should always clamp using a block.
The block does two things:
1. Protects work piece from indentations from the clamp face. You don't have to over-tighten to get indentations. Softer woods and plywoods often are not hard enough to accept suitable clamping pressure.
2. Distributes the clamping pressure more uniformly over a larger area. In this case, I would have a simple 2x4 cut to the length of the cab joint and apply multiple clamps.
One of the most common errors, if not the most common error, in woodworking is not appropriately applying clamps. Hint: there is no such thing as too many clamps.
Yep blocks (called Cauls by us woodworkers) help bring even pressure across a panel.
When I did the test run (before applying glue), the parts locked perfectly together with no gaps at all with the clamps as shown.
So I did not want to "fake it" when that is exactly all the repair needed.
I've had other games that needed 5 total clamps & 2 Cauls to resquare the cab, so it's not one size fits all.
I once fixed a cab with 2 ratchet straps and some waxed paper around the corner to keep the glue from forever sticking the the straps.
It was in a restaurant and I did not have any tools with me except the straps, lol. The owner had some Elmers glue. Still holding to this day.
I've got a SBM in the shop right now with the whole front panel off, I'll see what it takes to fix it, and post pics (of course).
