Building FF Upper Cabinets

[Jamie Buxton]

I use 3/4 ply for the top, bottom, and sides. The added thickness gives plenty of meat in the corners where the joinery is. I use 1/4" for the back. There's a nail rail at the top, either inside the box, or better yet outside, for cabinets that don't go to the ceiling. There's no reason for thicker material on the back. The spray finish goes on before the back gets stapled on the rear.
