Yes, the box is screwed to the Miter, and the miter is what slides through those channels in the cast iron table. At this point, I pretty much consider the jig and miter a single tool. This miter will be married to the jig, and I will simply buy another one. Once I get all the slots worked out (I'm afraid to make any changes yet! LOL), I'll probably epoxy the jig to the miter so there is no chance for drift. Part of my problem with the old jig is that the slightest changes in anything threw it all off. This should be pretty repeatable.

Yes, the key actually goes completely through the bottom panel. So it's held in place at the ends of the jig, and all across the bottom. I think the miter has more "play" in it than the aluminum key.
I have an assembly jig already designed in my head to help me speed up gluing the tiles in...but I'm not sure I'm going to build it for the prime 29 unless I build more than two units. It would take me so long to build the assembly jig, that I might as well just chug through placing each tile by hand for these bad boys.
I just really need to get a good idea for the tile cutting jig. There has to be a good way to quickly and accurately cut 1682 tiles....
Waiting for Fullness.
If this continues to work well, I've already got plans for my next batch of 2D diffusers. They will be 2' X 2', N11, and 6" deep. I'd like to make a fleet of them for my guitar room. They should be hugely easier than the Prime 29.
