I was able to get a pretty good deal on some rough Walnut and plan on making 3 Bar height tables about 42" by 72". The Walnut is just over 1 inch right now but once I clean it up I am sure it will be thinner than 1 inch. Would this be to thin for a table top. I had thought about doubling up the boards but do not have enough wood to double up all the tables and also not sure if that would make the top to heavy. Would it make more sense to maybe just double up the edges say the last 6" and then add a few boards on the underside to stiffing and strengthen, Or maybe get 1/2" play wood about 30" x 60" for the main base and then attach the top to it, or would their be a better way to do this? I was thinking of either using metal hairpin legs or maybe pipe legs on the table.
