I was asked to make a 9 1/2 foot long farm table with painted legs and Red Oak top. Here are some beginning pictures of bench construction. The benches are a little over 8 feet long and I've tried to design them to support 800 pounds. I hope they never see that, but it is possible. Most joints are dominos (big ones) but the center brace is held by screws. Additional boards will be glued to the outside edges around the bend structure so that there are 5 3/4 inch by 4 inch boards supporting the load.
