I may have bitten off more than I can chew here!
I have a bar top with edge glued boards made to a 24" depth and about 8 feet long.
I started with my belt sander and 120 grit paper to remove most of the lip between each board.
I've moved to a random orbital sander now, and I have nice smooth grain left to right, but forward to back I have quite a bit of waviness.
I'd like to level it out some: so that the end finish isn't wavy, and to keep cups from rocking (although I bet the waviness is over a long enough span that it wouldn't be an issue).
What's my best bet here? A manual hand plane?
