Hi -
I have a flat 18"x20"x3/4" piece of birch ply edged with 3/4" maple that I'm going to use for a simple (portable) router table top. I live near Boston (humid summer, dry winter) and do my ww'ing in the basement. Even though I run a dehumidifier, wood I bring in the basement to sit for a few days will often twist (hardwoods not so much). Considering that this is quality plywood I'm wondering if there's any reason to apply a couple coats of poly for sealing purposes?
I also have a straight/sq piece of maple (2x3, two pieces of 1x3 glued together) I'll use for a simple fence - any reason for a couple coats of poly on that? I don't especially like poly (and prefer the feel of natural wood anyway) so unless it will make a big difference I'd rather not apply it to either of these.
Thanks...
Mike
