I'm wondering how much I can trust the original glue in those places it is still holding.
I alternate between thinking that keeping the pieces together that are still together will be the easier route,and thinking it will be simpler to take it completely apart and start over.
We'll see.

Re: StewMac fiddle kit
No, this is not a duplicate -- at least not yet.The forum software was acting up the other day, possibly because I can''t type anymore. Anyway, I'll go back to zero and start over. I think I was describing the problems I see in gluing all the pieces together, the main one being the corner and end blocks and the side ribs are all already cut to particular sizes and angles. They have to be positioned so if points A and B were 4.587" apart when the violin was first assembled, points A and B ought to be 4.587" apart when all the pieces are reassembled. I've got what I hope is a sufficiently Cunning Scheme to get me there.'
See photo, below. I traced the top and cut it out, It's not precise,o but I'm hoping it is precise enough ts let me estimate the positions of the corner blocks fairly well. I set the blocks approximately in position, then held them in place with some pieces of 1/2" square tubing, held down at the ends with screws going into the cut out tracing block. The photo shows the blocks on the four "points" held in position, and the tail block also held in position...approximately. Now what I should be able to do is adjust their locations slightly as I attempt to add the side ribs that go between them. adjusting everything until it matches the way it was originally, or at least "close enough." Maybe.
Once it's all together and glued, I simply glue on the top and bottom plates. line up the neck, and away we go!
Not quite. There is another potential problem. Anybody else taken the back off a guitar? How well did it fit going back on? Yeah, the sides move around slightly when the back comes off. When I unclamp this assembly, it's going to move. No idea how much. I can start with an arbitrary block, gluing them down in sequence, hoping I can get all of them to end up where they should be, or at least "close enough." Another idea; after gluing everything together,but before unclamping, take some thin strips of wood and glue them to the tops of the blocks, triangulating them so the blocks are rigidlly located. Remove the clamps, lift the assembly off the board, and glue the other ends of the blocks and ribs to the back (or front) plate, then remove the triangulating strips.
Does any of that make any sense whatsoever?
