Arlo, January 9, 2011. Polaroid Big Shot and type 669 film.
I’m seeing that I’m going to have to clean the spreaders on the Big Shot (the camera I’m using) after each pack. It likes to eat these film sandwiches. Luckily, I’ve made it most of the way through this pack so far (crossing fingers I make it through film 10). The key is to pull them perfectly straight–any slight angle brings the edges of the film paper against the sharper edges of the film spreaders.

I just purchased a Square Shooter 2, which took the extinct Type 80 square film. The roller assembly is mounted on a plastic bracket. Just won a Big Shot on an online auction. I plan on pulling the spreaders out of that, and putting rollers into the Big Shot. After trying a Colorpack 2 with spreaders, told myself I would never use them again. Tested the rollers in that camera- works perfectly! Please take a look at my blog, which covers all things Polaroid, at http://www.arthurpolaroid.wordpress.com Best regards, Arthur
Brilliant, Arthur. I have a ton of obsolete and broken cameras stored away, and I know I have a Square Shooter among them. I couldn’t throw it out because I grew up with one as a toy–my parents must have outgrown it or broken it. I was fascinated by the squeezable red plastic around the shutter button. Anyway, I’ll try cannibalizing that or something else.
I actually have a ton of the rollers that I bought from someone who had them as replacement parts. But really, they’re the most solid things in most of these cameras!
Edit: I just looked and it was a Swinger I had, not a Square Shooter. Bummer. Not the same roller assembly at all!
