I am building a book shelf, for a customer, out of maple plywood in a my garage which is unheated. My question is how much will it expand when I take it inside to install? It is a modern design which involved inserting the supports in the center of the shelves. Which means I routed out a 3/4 inch hole for 3/4 inch lumber. Should I plane down that lumber and by how much?
Thanks, RTX

Don't worry about it. Check your support wood to be sure it is really 3/4". The movement due to temperature is too small to matter.

Right, and along with that the material of choice here is plywood so wood changes will be miniscule.

You need to explain this some more.
From the first sentence I was invisioning it being a "float" or "hidden support" shelf. For those you have a posts that sticks out of the wall and the there are horizontal holes in the self that slide over the post.
But for that, you clearly can't have a 3/4" dis hole in a 3/4" thick self.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
redtoolbox,
plywood doesn't swell as much as solid wood will. wood swells due to moisture not temps and plywood because the direction each layer is laid at is opposite it will shrink and swell the least...
Not to split hairs, but is your plywood exactly 3/4" thick?
