Huh!! I have always wanted to make my White FR treadle hand-crankable, but I thought the reverse turning direction of the wheel made it unworkable. It never occurred to me that the standard hand cranks would also work if cranked the other way. Now to line them up and see what mods I would have to make to work it. One the other hand...considering the size of the head and how smoothly it treadles, maybe I should leave well enough alone!
