Am building a bench with double 3/4 plywood top and removable three legs. It will sit here at the farm mostly, but will be "somewhat portable" so it can be moved in the truck bed or tractor bucket.

Using right/left center arm design, and here is where I am stopped; layed it out as 36"-40" wide on front, 46-48" long, with 18" cutout for left/right. This is larger than most movable tables which seem too small on the layout board.

Any suggestions from those that have built one?
