Is a laminated top necessery?
I made a 2" thick top of birch, which I intend to use as a router top. I might reduce the thickness a bit, but ït'll at least be 1,5". I planned to use it like that, with no formica, plastic or anything else on top.
Is that a bad idea? I'm concerned that it might warp over time. I thought about routing a couple of dovetail slots across the boards underneath, and glue some hard wood in there, or even a couple of metal bars, to keep it flat.
Any advice is appreciated.
