I grab every piece of underlayment I can find in dumpsters… and use it for all sorts stuff - but not exterior walls

It is great for quick-n-dirty shop projects, small boxes and organizers, small drawers and drawer dividers, scroll saw stuff if you are into that, and I even made the motor cover for my table saw out of it. Strong but lightweight, cuts easily and glues up great. Plus - the price is right.

Cheers,
Brad
