Hi all,
I’ll be building my uppers pretty soon. I have a few where the doors will close into each other – no center stile- and thus about a 30” span on the shelves.

I don’t think 3/4” ply with an edging is going to span that. So would it be crazy to make my shelves out of solid stock? And how would I best join the shelves to the plywood carcass sides?
If I do shelf pins, won’t they cup? Just loose in a dado?

Or maybe small cleats above and below the shelf screwed into walls that capture it and allow it to expand/contract?

Thanks!

On the 30” shelves, use ply ‘cause solid will warp for sure. If possible, drill the center of the cab back same as the sides so you can put a shelf pin in the back for support. Won’t be as good as having the support front and back, but better than nothin’.
I’ve never had a shelf pin cabinet fail if the holes are drilled correctly.

The Sagulator says 0.01” total sag (0.004” per foot) for plywood over the span of the shelf. No worries.

One meter. 8 years. No warp.Sitting on 3/4 cleats. 3/4 solid mahogany.I don’t know that I’d try it with Disneywood(glued scrap).
Yes. T&G in back and on top. Don’t all “custom” builders do that ? ;-)

-- What day is it ? No matter. Ummmm What month is it ? No moron. I paid for a 2 x 6. That means Two inches by six inches. I want the rest of my wood.

Have your say...
