After I posted this it occured to me that boards run flat into the table-saw with the blade at full height gets me pretty close to the rough angle I need. That would cut down on hogging.

More sensibly, If I just use 8/4 stock with two toes, the interior short piece can be cut exact and the outside longer pieces cut after assembly. The pieces with two short boards on the outside can be cut on the table-saw after assembly too. I don’t get as much grain-2-grain strength as with 1” stock but this only has to hold a 15 lb. speaker. It also has to be cat and puppy-proof —or puppy-resistant anyway.

I thought about the splines but the idea is to give this support against being squeezed in. It will want to open like a hinge. With splines I’ve got end-grain on end-grain for most of the surface. Splines cut to look like fingers should be stronger. A hidden spline running the length of the gluing surface—not so much. It would have to be cut with the grain running perpendicular to the spline. I’ve used BB ply in situations like that.

I’m not married to any of this but the idea of making a TS jig to support a hunk of oak that big and then tuning it for every cut seems unwieldy.

Thanks, sh
