Hi, this is my first post. As a hobbyist woodworker, I've lurked on this site for a while as I honed my skills and built my tool collection. In fact, the site's so helpful that I usually just type my woodworking question site:sawmillcreek.org into Google so I can get straight to the answer!
I'm about to get started on a set of bookshelves for my house. I was going to use 3/4" oak plywood in the most efficient manner possible (the cost of hardwood plywood adds up quickly!), and then edge-band solid oak to hide the plies where necessary.
I stumbled on what appears to be a great deal. A gentleman in a neighboring city has offered me 21 sheets of black walnut plywood for a fraction of the cost I'd expect to pay. It bears no markings (no manufacturers stamps on the plies), so I can't figure out the source. The seller told me it's high quality black walnut veneer on one side and birch veneer on the other, and it came from a lumber wholesaler/distributor. I'm inclined to believe the seller because he is the owner of a reputable business, and this plywood is apparently left over from a very large project. It's beautiful and certainly looks and feels nicer than the nicest plywood I've ever encountered -- but I'm no pro. The lumberyard nearby sells black walnut plywood for $139/sheet, so this sounds like a good deal.
Anyone ever stumbled across something like this and later regretted it?
