Cutting Angles in Plywood Sheets

Well, I was ready to go out and buy your dream. But I'd have to move
the Ferrari and Hummer out of the garage to make room for it.

Joe, I like your idea about attaching the miter slot runner to the wood
for cutting it. I'll have to try it sometime.

A skil saw and a straight edge will do the trick. Buy a fine tooth carbide
thin kerf blade for the skil saw.
Skil saw is not a brand in this context, but the type of saw.

If you are using veneer plywood, put a piece of masking tape over the cut
line first, this will reduce tearout. (Just be careful when you remove the
tape.)

I have cut large pieces of plywood on my table saw by attaching a long 3/8 x
3/4" piece of oak to the plywood to the appropriate place with small nails
on the underside. This strip can then ride in the miter slot on your saw
with out hte need for a fence or miter gauge. just draw your cut line,
measure the distance between the blade and the miter slot and attache the
strip at this offset. It works quite well.

Clamp a straight-edge and use a circular saw.

I think I'd modify the design so that the panels joined to a solid wood
'post' at the corner. Maybe with a rabbet.

You're likely going to want to reinforce that joint in any case.

I have a solution which is much more fun:

Clamp a straight edge and use a circular saw -

But I would use my table saw for cutting the SQUARE accurately (precut
a bit oversize with circular and then use the straight edge to do the
corner cutoff

You may also want to score along the cut line with a razor knife
doing this extra step will eliminate tearout of fragile veneers.

Good luck with your project
