Thank you for a very detailed expert answer! That's exactly what I was afraid of. Do you think if I stick with Singer machines and Singer cabinets/treadle irons there would be fewer problems with the alignment of the machine's belt groove & the flywheel below? I would be willing to modify the cabinet if necessary. The ultimate goal is to have a treadle machine that works well. Aesthetics aren't as much of an issue to me -- I just prefer using a treadle machine for most of my sewing (although I often do small piecing on my beautiful 1938 Featherweight!).
Thanks for sharing your experiences! It really helps!
