OK. I have watched the youtube videos on fmq and think with a treadle might not be so challenged as have been on other attempts. Only problem, the sound is not good on computer and I can not catch the name of the foot I need. I would be using it on my White Rotary 1911. Search word suggestions for looking on ebay? Or a pic of what I am looking for. The one in video looks to me like a darning foot?
