What tool would you use

When I said bandsaw, here's what I meant.

Most of these are made this way. You build a normal rectangular box to the dimensions you want. The depth of the box is the depth of the deepest side PLUS the depth of the short side plus a little bit extra for the kerf and clean up.

Now take it to the bandsaw and rip it apart at the proper angle . Bingo, now you have two boxes. finish up with some clean up on the edges.

You can make a jig to hold the box at the correct angle on the fence. the jig rides along the straight fence and the holds the box at the angle. Can be as simple as a piece of mdf with a strip down the length at the correct angle. or more complex if you are going to make a bunch of them.

Tracksaw and miter saw for me. Tracksaw to size the panels. The tapered panel look to be symmetrical so I would come up with a pattern. Then cut the miters on the chop saw. If it is solid stock I would use dominos in those miters. I have a big band saw but I wouldn't make a box then cut it in half as there is too much potential for variation from the top to bottom cut. And it would be tedious and I would have to clean up the band saw cut a lot more than a tracksaw cut. The lights I would bore out with a flat bottom forstner bit.

You're two hours ahead of me, Mario, hence you didn't see my sketch until now. The sled is more or less a panel-cutting sled but without the fence. Instead two angled subfences are installed to trap the stock to be tapered. The simplest way to lay out those angled fences (without measuring) is to cut a tapered cardboard (actual size) and use the cardboard to position the subfences for screwing.

If all tapered pieces are identical in size, you can use it with a runner; otherwise use it with the saw fence. For consistency, I'd taper two pieces together at the same time.

For smaller pieces, I can simply add an angled fence on my panel-cutting fence to taper them -- see second image.

Edit: If you decide to miter the pieces, dominoes are one way to reinforce the joint. Brads, however, are the simplest and quickest way, and this is the kind of wall shelf project one can probably get away with using wood putty (which usually is a no-no for me).

Thank you Chuck for the drawing  [big grin] you know me pretty well  [embarassed]

Someones already mentioned it but I'd make two at a time.
Make a rectangular shape with mitred corners then cut it in two to get two tapered sided parts.
Obviously that would result in four tapering rectangular shelves. Err. Win win.
Oh and I'd do the long cuts with a TS55,HKC or just a normal circular saw and likely just finish the cuts off with a handsaw to get the full depth and clean it up with a blockplane.

You could do the whole taperered cut with a handsaw, like making an old style carpenters box where you make the closed box shape then more or less cut it in half and put piano hinges on it so the lid can be opened.

Are your dimensions in inches? Or some other unit of measure? 

My thought would be to make a rectangular box big enough to create two of the assemblies by cutting it at the taper angle. You’d get two assemblies by cutting it at the bandsaw along the tapered edge. Could do the third assembly similarly, but from a smaller sized box.

This is all assuming one has a large enough bandsaw to cut your rectangular box through their assembled height.

^^^ This is the way I think I would go. Build two boxes, then cut each diagonally at the desired angle with bandsaw. Then you have easier assembly and four identical tapered boxes. Toss the extra box and you good to go.

^^^ Another vote for the above. It will make cutting parts and glue up so much easier. Just make sure you don't cut through a domino or whatever enforcement you use. As for the tool I'd use track saw, then finish up with hand saw and block plane.
