I've got Tom Clark's cabinet making book and I'm trying to build some cabinets for the shop. Maybe I'm making it harder than it needs to be, but I don't understand his dimensioning for the drawers. I've got the total height of the cabinets, less the upper and lower face frame width dimensions. That leaves me with a dimension of "X" which I need to divide up into my drawer depths. So, with his description, (if I want, say, 4 drawers) I just decide what depth I want each drawer to be, and divide "X" into those dimensions? Does that mean if I want the bottom drawer to be twelve inches, I just measure up 12" from the bottom face frame and screw in the "doubler and drawer glide" for the next (upper) drawer? And if the second drawer is, say 8", just measure up another 8" and screw in the doubler next drawer? In other words, am I just spacing the drawer mounts now, and "fitting" the false fronts to fit the opening later? I know I'm making more of this than I need to, but better now than later! Thanks. Greg
