I got one of Norm's old books from the library.
Basically, he was making a table top with a solid wood slab. One the underside of the table top, he screwed four long boards perpendicular to the grain. Is this a legit technique, or would it cause the table top to crack when cross grain movement occurs?
If that's a legit technique, I could see using it to help keep the tabletop flat. Opinions? Thanks.
