I am going to build a bar top for some friends out of reclaimed pine and red fir. The material is very rough, so I will plane down to about 1.5" thick. Should I rip it to about three inches thick and butcher block it, or lay it flat. One portion will overhang about ten inches on both sides of the bar, with pieces about three feet long. I don't want it to warp and crack over time. Anyone have any advice?
