Hi barkerclaudia, you are absolutely right about using the cable tie, or zip tie, please use those only on small weaker springs, and my post showing it with the large mainspring was to position the spring and not actually hold it. the mainspring also has a steel “c-clamp” on it, as always use caution with these mainsprings, I had used a lighter weight wire once and the mainspring pulled that right apart, I too learned a lesson, As Bob says in the video, “use a hefty wire” and for good reason as we both now know. take care and hope you find a new wheel , possible if you had more info on the works, arbor diameter, wheel diameter, thickness and # of leaves or teeth someone may have one.
