Plywood's more dimensionally stable because the plys are aligned at different angles, thats the good news. The bad news is even with the "fancy" plywood blades that stuff chips pretty well depending on glue bond. My luck is whenever I don't care what a plywood cut looks like, it looks like it was cut with a laser, and when I really need nice edges its inevitably not my lucky day. Of course there are tricks to that too, like cutting really one really wide board and letting it chip out all it wants and then ripping to width at the end of the project.
I'll have to think further about the whole wood issue. On Mon, Jul 14, 2014 at 6:14 PM, J.
