How to Make a Fully Functional 110 Film Developing Reel

19

Just last week I placed a bid on a lovely camera: a Pentax Auto 110. This small but very well built camera is the cutest and tiniest SLR I have ever seen. When I won the auction I started preparing for its arrival: buy some batteries, order some film, find a developing reel... And that's where I ran into trouble! As hard as I tried, I couldn't find a reel to develop 110 film, anywhere! So I had to pull up my sleeves and get dirty.

When I bought the Pentax Auto 110 I didn’t realize it would be so hard to find a developing reel for this small format film. But since I had been developing all my own film for the last two months, B&W, color, 35mm, and 120, I had no intention to return to my old ways and drop it off at the lab. Surely there was a solution out there.

Truth is, there are a couple of options, but none turned out in my favor. First, there is the Yankee Clipper II tank. This tank comes with an adjustable reel that will take 110 film. Problem: it is out of stock. By a stroke of luck I found a second hand tank in the US, but the incredulous shipping fee didn’t make it a feasible option. Second, I was told the older version of the Paterson system, the Paterson Universal 3, also comes with a reel for 110. Problem: they have been out of production for decades, and waiting for a used one to pass by on an auction site would take forever, so again, not an option. Third possibility: it appears there are some stainless steel reels out there. Problem: this reel wouldn’t work with any of my developing tanks. So I got left with the least desirable option: if you can’t buy it, you make it!

Looking for online instructions on how I would best approach this led me to this tutorial. Though the basic idea was good, start from a normal Paterson reel and cut it down to fit 110, the outcome presented looked a bit like a brutal hack job.

Taken from instructables

On top of the ragged look it had also lost all functionality:

  • The ball bearings were taken out, so no more automatic film feeding
  • The reel was glued shut, fixed, no more possibility to open it up and carefully remove your freshly developed film.

Both are features that I didn’t want to lose in my version of a 110 reel. The ball bearings are what makes spooling your film in a dark bag so much easier, and being able to open the reel helps prevent unnecessary scratching of your wet film. Somehow I managed to produce a 110 reel that remained fully functional and the best thing is it took me less than 10 minutes. Here is how in 3 simple steps:

Step 1: resize the center tube with the biggest diameter

You have to size down the tube to 12mm (or as close to that as possible). To make things easier I put some red tape around the tube at the correct distance and used a fine metal saw to do the cutting. When it’s done, you can sand down any sharp edges. Don’t throw away the piece of tube you just cut off, you’ll need it!

Step 2: remove a very small but very specific piece from the center tube with smallest diameter

The piece you need to remove is the small triangular shape that serves as a stop when closing the reel. Look closely to the before and after pics below.

Step 3: resize the piece of tube you just cut of

The idea is to keep the reel so that it can be opened and closed, therefore no glue can be used. Instead we’ll use the small tube we just cut off. If you look it the inside you’ll see the structures used for locking and unlocking the reel. Those can still be used, just on a different position on the tube. The smallest diameter tube has 3 positions for these structures to lock in to: close to the base, somewhere halfway up, and at the very top. That’s where we want them to be. So flip the tube so that the locking structures are up and slide it down the smaller tube (this will only be possible if step 2 was done right, if it doesn’t slide over the thinner tube locate the obstruction and cut it away with a knife). In my case, the tube was 2mm too high for the locking mechanism to take. So I sliced away thin slivers of plastic until it did take. A good sanding might also do the trick. If you have trouble understanding what I just explained, take a good look at the pictures below and it will become clear.

That’s it, you’re all done! Just put the pieces together and your good to start developing 110 film!

To prove to you all that it works well, I did a little functionality test. Check out the video!

    Have you started developing yet? I recently modified this same spool for 110, but somehow my film doesn't get coverd in chemicals properly when I use it. (See www.lomography.com/homes/stratski/albums/1957339-110-develo…) Perhaps it's because I usa a Jobo Autolab, and I should try developing by hand... I''m interested in yoyr results.

    Hi @Stratski, I ran one film using this reel (orca bw 100) and that came out fine (haven't uploaded it here). Then I sadly discovered my new pentax auto 110 doesn't work without the flash, so I had to return it... The adjusted reel hasn't seen anymore action since. I used a system 4 paterson tank, stand development. When I opended the reel after the final wash, the film was sitting in the weel, perfectly spaced as any other format film. Since I no longer have a 110 camera you could have my adjusted reel, ;-)

    I keep forgetting this @username is case sensitive... @stratski, the previous message was for you ;-)

    I took a 35mm spool, modified it and it is working fine. I took a Jobo spool for the 1500 system (www.jobo.com/(…).854.0.html) and shortened the spool with the bigger inside diameter to a lenght of approax 8mm. I have uploaded some picture here: https://plus.google.com/photos/105212484178882702941/albums…

    @sandravo, @ck_berlin: Thanks! I guess I should just try again, maybe do a roll by hand just to be sure. I should hang on to your spool for now if I were you, you never know what you run into...

    @ck_berlin Thanks for your input! Surely the Jobo users will appreciate it! Looks pretty similar to what I did. How does the reel stay closed? Can you still snap it in place or did you glue it shut? I have never used Jobo tanks, so I'm clueless :-)

    @stratski I have been on the look out for another pentax auto 110, which I adored! Found one in the Netherlands but the owner won't ship to Belgium :-( Any other great little 110 SLRs out there I should know about?

    @sandravo: Bummer! Keep looking, I'd say. I got mine by coincidence at a local flea market I happened to pass.

    My girlfriend bought the Pentax 110 yesterday too - such a cute camera! We'll check if our local laboratory develops the films, and if not, we really need this tipster <3 thanks for sharing!

    @shoujouai It's cute but it is so real! It doesn't feel like a toy but like a real SLR! Loved how easy it is to focus! I need to find a replacement!!!!

    You're a genius!!! Just finished mine and it's awesome! Thank you for the great tip! :-)))

    @maria_vlachou Awesome that you tried it out! Even better that it works! Just a tip to make opening and closing a bit easier: the small piece of tube can be slippery when it's wet, so keep a rubber band or one of those rubber bracelets (like the live strong bracelets) nearby. The rubber gives you a very good grip.

    @atria007 Here you go my friend, the article that goes with the video: how to make your own 110 paterson reel.

    Thanks for the heads up! Now I can start developing all those 110s that I shot ages ago! :-)

    Very cool! Although, I think I'll never shoot 110 : )

    Great! I have a Paterson System 4 tank too and I will use your method to develop 110 films!

    Just a belated thank you for this. I had some spare older Paterson reels. They don't have the triangular stop but otherwise the whole procedure worked for these as well.
