Here are ASCII diagrams of what he has in mind

The problem was cutting the stopped miter on the bottom of the ply sides. Since the ply sides are 15 inches wide, a miter saw was out. Cutting a stopped miter that's only 2" long on the table saw is also awkward, especially when the sides are 29 1/4" tall. A 45 degree chamfer bit however could work - at least to cut enough of the miter to make hand cutting the rest relatively easy IF you have a fence you can move precisely AND a zero clearance insert in the fence. The JoinTech Cabinet Maker system I have has both. So the idea could be done by a newbie like my son ( who, BTW is 27, though I still call him The Kid).
Unfortunately, the chamfer bit I had would only do up to 1/2" stock and the ply sides are 3/4". Solution: A great excuse to get a 3/4" chamfer bit!
Did a test joint today and it works! One cut with a dovetail saw and some simple chisel work finishes off the last half inch the round chamfer bit can't cut. It will require some climb cuts but if he goes in small increments and uses a feather board to hold the stock against the fence it should be something he can do.
I'm sure he doesn't realize that the harder part will be cutting the toe kick board to precisely the right length.
Wonder what he'll come up with next.
Fun this woodworking thing.. charlie b
