Mamiya rb67 pro s winding issue

[ig: @ianbaltz]

I’ve had my pro s for just over a week now so i’ve only shot 3 rolls with it and only developed 2. The first one i developed, the spacing was a little inconsistent but nothing overlapped and i got all 10 frames. but the frames on the second one, which i shot exactly like i did the first, are all spaced super far apart so i ended up only getting 8 pictures. it’s also strange bc they aren’t inconsistently far apart, the gaps are uniform, and i’m assuming the film back isn’t supposed to leave 1 1/2 inch gaps between exposures. anyway, if anyone has any advice on whether they’ve encountered this issue or how i could solve it i’d really appreciate it!

Frame Spacing Changes from Roll to Roll

Since all this is new to you(?), inconsistent spacing just might be due to your loading technique--right and tight one roll#1, not so much on roll#2?

Mamiya RB film inserts aren't fragile. That and the fact one roll was OK but another mis-spaced suggest loading issues. Assuming you're shooting 120 in 120 insert?

i’m using 120, yes. the back i have also has an issue with the counter but i believe that’s unrelated. i think i’m just going to have to run a few more rolls through it while winding and loading it more carefully to see if the problem persists. thanks for your help!
