I’ve figured out how to treadle and there is definitely a technique to it! But I noticed that there’s a rod that’s attached to both the treadle and the metal piece that helps move the belt and it’s un-screwing itself as I treadle. So every time I am sewing, I have to take a peak underneath after a while and check to see if the screw needs to be tightened up again, because otherwise it just falls off. I will take a picture of the rod tomorrow so you know what I’m talking about.
