I guess this would be the place to ask this question. I have a treadle & accidentally acquired a hand-crank. I have not played with it because I can't figure out how to crank with one hand and do everything else with my left hand. I've always been too embarrassed to ask, but that hasn't gotten me any answers. Any help would be appreciated as we live out in the country & our power goes out with a strong wind, much less storms. Thanks in advance.
