MIssing Thumbwheel

Hey guys, on my Rz 67 120 back im missing the thumbwheel that winds the film, i know that you can wind the film with the cocking lever, however because the wheel is missing there is no tension created on the spool,
does anyone know where i can get another wheel? or a DIY quick fix till i can get another?

Ughhhh. That's a tough one. I don't have an answer. I would recommend calling a good camera repair shop and asking them. You should probably also take a look at the Mamiya forums Mamiya USA has on their own Web site. And if you're into doing your own repair, you might look into buying a broken body for parts. In fact, that might be the best answer. Check Adorama, B&H, and KEH to see if they have any parts cameras for sale. That's what I'd do. But I don't know that body well enough to know of a quicker fix.

Good luck and please let us know what you end up doing. I'm curious.
