Welcome to the boards and to the world of sewing and machines! We have many types of people and many skill levels here. My construction working neighbor borrowed one of my machines to make masks for his family during Covid, and while he has since chosen not to go that route, was thinking about going into upholstery when he found he enjoyed "playing" with the sewing machine.
What fun to have/be able to restore a treadle. While I hope you do indeed end up sewing a stitch or two, you don't have to, for some the machines are more than enough...
