I'm currently working on a standard 16mm Arri SR Mag that has a loose feed wheel. Since the wheel itself isn't tied down by screws, and t's slowly starting to come completely off due to one of the non-screws (I'm sorry I don't know the term) not being attached to the feed side at all. In the mean time I used the mags we have for spare parts to replace the feed side entirely. It's not 100% broken, everything else is fine with it but it's just the wheel that's got to be figured out I'm just not sure how. Any tips or references I can go to figure out this problem? Will respond with photos soon Thank you everyone!
