Since this thread has been resurrected I'll add my roubo. The top is made from four 4x6x8' glued together. The legs are 6x6s and the stretchers are 4x4s. Everything is douglass fir except the leg vise which is maple. I'll be moving a couple times in the next few years so its designed to come apart. The top is attached with big mortise and tenons and currently is just sitting there with no glue. The long stretchers are attached with benchcrafted bench bolts and the short stretchers are draw bored. I did most the work by hand but used a planer towards the end as my arms were about to fall off. The douglass fir was all green and I don't think a single board remained flat or square after drying. If I were to do it all over again I'd try to find one or two big pieces for the top or use a jointer and planer and use some 4x4's I found that were really tight grained.
