Glad you found something that will work for you. My new machine doesn't need a screw driver for the throat plate, it just pops in place. My old treadle has a cute screwdriver with a triangle handle that I think came with the machine and I like it a lot. I must admit that my hands don't want to grasp and turn tiny things so well now either. I find myself buying water bottles with the wider tops for that reason. I also love my mandolin for slicing vegetables rather than a peeling knife. It's a great feeling when you find something new that works for you!
