shear "give" layer

General Discussion
1

I don’t know what else to call it.

I’m going to make a compsand. I’m hoping to use 1/8" paulownia skins. I will be using balsa on the rails. I’ve heard of problems of cracking at the rail join. I was thinking of putting one layer of cork between the rails and rest of the board. My thinking was that the cork would have some “give” if the rail and center flex at slightly different rates, thus avoiding the cracking.

Any thoughts?

Seems like I remember reading here that cork absorbs resin etc like a sumbitch, so there’s that, sorta
