I'm about ready to build a fairly elaborate cabinetry system for our walk-in closet and already own Marc Sommerfeld's T&G cabineting making system. I purchased it a couple of years ago and have used it on solid wood jobs but not on plywood. I think it works very well. I have a very good hardwood dealer close by who has cabinet grade birch veneer plywood. Considering the inevitable thickness differences in 3/4" plywood, has anyone run into problems using the system with a decent grade of plywood. Also, can anyone tell me why Marc offsets the T&G by 1/8" from the edge? I suspect it is to hide any tearout. I also have a Domino and would appreciate opinions on building plywood cabinet boxes using the T&G system vs the Domino. Thanks.
