I've been doing some research. I think I understand what you're saying.
First, I didn't wind the film leader far enough. Second, film is thinner. A "one-two punch."
I think I'm going to try another roll. I'll pad the take up spool with a couple-three layers of gaffer's tape and I'll make sure I wind the film on far enough to get that extra lap of leader around the spool. Hoping that will solve the problem or, at least, alleviate it to a degree.
I really like this camera. I like the way it feels and the way it works. I like the synchronized aperture/shutter. I like the fact that it is a 120 film camera with a form factor that I'm more used to. I like my Yashica and Roleicord but I grew up on 35mm cameras so that is what I'm most familiar with. I am adjusting to using the TLRs but I have to be in the right mood. I think this camera will be a good "go between" for me.
This is probably going to be one that I send in for CLA and keep as a shooter.
Thanks for the help! It's clear that I've got a lot of studying ahead of me!
