Advancing 110 film manually

February 12, 2006 12:01 PM

I just built a tiny pinhole camera that mounts onto a 110 film cartridge. The directions I've found call for using a coin to turn the tiny gear to advance the film. I can't get that to work really at all. Any advice?

I slightly modified these directions (sorry, Flash). They say: "On the top of the cartridge, you should see a raised disk with a gear inside. ... Using a coin, turn the gear counter-clockwise..." Since even a ridged coin like a quarter hardly has any grip on the gear whatsoever, it takes all of my dexterity to get it to advance the film at all. And the gear has a lot of give (at least half a turn) before it actually starts pulling on the film, so trying to just push it forward with a paperclip doesn't seem to do much.

What sort of "do it myself" solution can you think of?

Best answer: Okay, I figured it out myself. I used the tips of two pens at first, one to advance the gear, and the other to hold it in place (like a ratchet would) as I moved the first pen. After one or two exposures like that, it became much, much easier to turn, so now a coin is perfectly acceptible.

Response by poster: b1tr0t: This was a blizzard-inspired arts-and-crafts project. The film was $2.50 a roll, and development will be something like $3 a roll, and the photos will turn out horrible (if I'm exposing them right at all). But it's all about the fun.

In my experience you often won't even have to pay for the processing for films exposed in this way - the photo lab assumes that all of the photos were trashed, and waives the fee.

Wow. If any of your pictures turn out good, send them to The Sun . They often print photos made with pinhole camares. I've always been curious what the deal was with these cameras. Now that I know how low-tech they are, I will pay more attention the next time I come across a photo that was created this way. Good luck.

You can also use a flathead screwdriver.
