I'm working on my sofa tables, getting down to the bottom of my mahogany
pile and don't want to buy more at the moment.

I need two center supports, each 14 1/2 wide by 20" tall x 2 1/2"+-
thick.
I had planned to attach solid mahogany strips, 3/4" thick to a poplar
frame
but don't think I have enough mahogany stock for that. However, I
have some
12/4 offcuts that I could resaw and glue those to 1/2 or 3/4 ply,
attaching
the ply to the frame. The resaw pieces woild be a maximum of 1/4"
thick,
quarter sawn.but I could make them thinner, no thinner than 1/8".

My question is, what is the maximum thickness I could use for the resawn
pieces?



1/8 would be fine, but what you'll need to do is find in the lumber
charts a comparable wood that expands and contracts similarly and attach
it to the other side of the ply. That will balance the piece and
prevent warping.


I'm thinking that will not matter. A LOT of upper end cabinet quality
plywood has a good side and Luan for the back.

why not. Ply is always in odd number of layers to prevent warping. your
luan example creates a balance.

I think it does matter having balance. Always odd number of plys..

Alternating layers, not all grain running in the same direction.


yes, but you need an odd number of layers. It's never even. If it were,
it would pull in one direction.
