The original boards were ~10' cut to ~8' leaving 2' sections. Being both coincidence and planning, this gave me sections the width of the bench for the bottom shelf, the parallel bars, and the wheel supports.
Currently I have no access to a band saw, so I used my circular saw to re-saw the pieces. Was a little rough, but actually better and safer than I thought it would be.
I've left the pieces un-dressed; to allow the wood to continue to dry, and because the planner blades need a sharpen.
