I recently completed the first part of a project, a router table top, and now I’m planning/designing for the next part, the cabinet to put it on. I’m fairly new to woodworking so my projects so far are few and mostly shop stuff so I have very little practical experience although I’ve read and watched countless articles and videos. I’ve reviewed numerous examples, plans and how to videos for router tables and have gleaned the basic construction methods. My table is of non-standard dimensions since it was built for the Incra LS positioning system, short side to side and longer front to back, 29”x48”.
My question is about the carcass construction for the cabinet. I’ve seen configurations, or variations thereof, similar to picture 1:
My cabinet will have similar but I will need to define sections that are in line with each other as in picture 2:
This is not the actual configuration of my cabinet but it illustrates the basic concept of the question. Would it be better to break up the shelves/dividers with a single horizontal piece as in picture 3:
Or a single vertical piece as in picture 4:
And why? I’m planning to use some type of 3/4” plywood with 1/4” dados. Or, is it a bad idea to have a dado in the same location on each side of a piece because it would weaken it too much? Would a dado on just one side be sufficient since I’m planning to have rabbets/grooves in the back skin to help everything lock up?
Just now, while putting the post together and looking at the pictures again, I’m thinking that a single vertical piece would be better since it would provide support at the edge by the wood in compression versus a single horizontal piece hanging in the middle from the thin web left after the dados are cut. The middle horizontal pieces will not be load bearing though since nothing will be resting/hanging on them and all drawers will be attached via glides on the sides so maybe this isn’t a factor. Maybe ease of construction one way or the other is a bigger influence or maybe the forces at play are different and the cabinet as a whole would be stronger one way?
I have the basic layout of the cabinet complete; I’m just trying to figure out the joinery and what will work best. Eventually I can post some pictures of the top and my tentative cabinet design if that would be helpful.
