I'm getting ready to build two 52" dia octagon back yard (non covered) picnic tables, one for me and one for my daughter. I bought approx $600 of white oak for the project (should have some left over for other smaller projects). I am replacing one I built for myself over 20 years ago out of redwood as its falling apart (used Penofin oil on it for years). I have titebond 3 (advertises as waterproof) or maybe I should buy some epoxy. I live in central Calif, mild winters (lows of 24 sometimes) and hot summers, low humidity. My question is what type of glue would you use, Titebond 3 or epoxy? I have designed to take into account a little expansion and contraction. And also, would you oil it or leave it be and just let it weather? If oil, what have you used that you would recommend? Thanks. Randy
