Columbia AH - New Mainsprings
Posted: Wed May 01, 2024 8:09 pm
I am working on my Columbia AH early style first style. This is the one with the offset crank handle, the top mounted speed control, and the horizontally mounted motor. I need to get 2 new springs. I’ve measured them as best I can, but I would like confirmation from someone that has worked on one of these machines before. I think I need pears/pears, 1 inch diameter, and 10 feet in length with a ⅝ inch arbor. I know it’s a pretty geeky/technical graphophone question but does that sound right?
Any recommendations on where to buy these?
Thanks.
