Topic tags/keywords: question plywood wide cabinet

So, I am working on building a 6’ wide bookshelf/cabinet for our living room and am having trouble coming up with a solution for the back. My concern is having a seam down the middle of my cabinet if I split the sheet of 1/4”, and I am not a huge fan of having the grain run horizontal if I don’t have to. What kind of thoughts do you all have?

You can make a frame and panel back.

I have successfully edge glued 1/4 inch plywood to make backs wider the 4’. Reinforce the back with tape and leave it there.

So, you are saying put a stile down the middle and two panels on either side?

Can you order a 8×4 (grain runs 48” direction)
Otherwise I have done the same as AlaskaGuy

Yeah. I would make the frame, like a face frame
using pocket screws in the back maybe, cut a
rabbet in the back of the frame and nail the panels in.

Taping just the back?

What I do, is, make sure the 2 halves fit good making a tight seam.
I butt them together, run a couple of pieces of tape down the seam to hold them tight.
Then I fold the panels open and apply glue to the seam, then close them back flat and tape the back side.
At this point if you want to put some clamps on them, gently, you can but I never have felt the need.

After the glue has dried remove the tape from the face, leave the tape on the back.
If you taped the front good you shouldn’t get any glue squeeze out on the front, just out the back.

This is usually a custom layup. Some distributors stock them, but, it is usually at the request of some large operation that is buying units and units of them. (Red Oak and Maple in my market)
If no one like that is buying tons of them where you live, good luck finding 8×4’s of any species.

If you can press your own veneers, it is relatively easy to seam your veneer flitches and laminate 8X4 yourself.
(GLVeneer.com also stocks a pretty good variety of 8×4 veneers ready for your press – 30 species/cuts. Just don’t forget a balancing backer sheet)

I suppose it all depends on how desperately you want no seams as to how much effort you put into this endeavor.

Sounds like a whole lot of work and expense for a book case. Edge gluing is a practical solution.

I would either butt the two piece together with a real tight seam and a thin board glued on the back for insurance or put a nice figured board down the seam on the inside- maybe scalloped on both sides or something like that and it will look like you planned it that way.

Cheers, Jim

I’ve bought 8×4’s many times without having a custom layup.
I guess I have just been lucky that larger operations were using the same species that I needed at the time. ;)

AlaskaGuy, I don’t disagree necesssarily.
If I already had inventory, I might do as you suggest. It is not too difficult to join two panels as you suggest.

Mostly, the decision for me would be based on what I am set up to do best and what level of project I am working on. At the super-high end, it would be and is unacceptable to have a detectable seam in a back like that. Not everyone can pull it off, either (seaming 1/4” plywood).

If this is an exotic veneer panel, I am picking my flitches anyways, so it becomes no big hairy deal to lay it up.
If it is a more common furniture item, I might not be so picky.
As I said before, it all depends on how desperately you want no seams as to how much effort you put into this endeavor.

If you don’t mind a seam then you could make it show by making a double 1/4” rabbit on a 3/8×1,1/2” piece of contrasting wood and glue the two pieces to it and use it as a decorative seam.
otherwise glue do what Alaskaguy recommends. Or, just get some 3/8 stock and shiplap the back.
