We used to have a small cloths spinner that I was able to clip film spirals to which worked well. The only draw back was it had to be done in pairs to keep it balanced.

I got mine from Morrison's I think it was £3.50.. Like others have said I put two spools in to balance it out.

I remember seeing a device in the Kodak catalogue of the sixties. It was probably American and was intended for drying much longer lengths than 35mm or even 220. Microfilm, perhaps? I think the spiral was about 6...8" diameter. It was built in two halves - the bottom half housed a fan (i'm not sure if there was a heater) and a means of rotating the spiral. The top half was in the shape of a shallow bowl, the vertical surface lined with an absorbent material and contained the loaded spiral. I assumed that that spinning the spiral removed most of the water and the (warm?) air did the rest.
If anyone has a copy of a Kodak professional catalogue from that era, it would be an opportunity to fill out my faint recollection. |

In the sixties I saw press photographers drying 5x4" and 120 by immersing in tanks of methylated spirit. The first tank was water with meths and the next was neat meths. Not sure why. I heard that the film was rewashed after printing and before bagging and filing.

Thanks for that description, Jonathan. That sounds like the device I was thinking of. Perhaps it was actually intended for 35mm movie film. I was going to convert a food processor, but the salad spinner sounds a bit more straightforward. Draining from a food processor could be a problem as the motor is often directly below the container. The annoying thing is that I had a suitable machine which had outlived its usefulness in the kitchen, but has since been sent for recycling.

I imagine the methylated spirits would be akin to WD-40, displacing the water. A naked flame would then simply burn off the meth (which is now a weird abbreviation in today's world!). Instant evaporation. I had also read of newspaper darkroom workers printing the negatives whilst wet. Um, the negatives, not the workers. |

Printing wet

I was familiar with low-contrast 5" x 4" Ektachrome 6120 (gamma about 1.0), which was specifically designed for making duplicates, but the device I am describing was making 24 x 36mm slides that were not excessively contrasty. Maybe there was a low-contrast motion-picture stock available at the time? |

Spinning, is it overkill?
To be perfectly honest I have never found the need for anything else to leave my films streak and drying mark free other than using a water-bath with wetting agent. I have used the Kodak version for many many years and it has never given me a problem. I don't even use distilled or filtered water to make up the solution.
I have lived all over the country with a variety of water types from reasonably hard (in Sussex and North Yorkshire) to quite soft (in Co Durham). After the final wash for which I use my JOBO processor, the last step is to fill the tank with the final rinse and let it stand for 5 mins with one inversion every minute and then pour back into the bottle. The film is hung from a hook on a door lintel leading from the kitchen to the living room and will dry perfectly in around an hour. The only thing that I am particular with is to change the final rinse every 5 films, but as the wetting agent is so cheap the cost is negligible. |

Thanks, John. The issue at the moment is that I don’t have anywhere I can safely hang the film undisturbed. I’m aiming for a quicker drying time.

By all means shake the spiral still with the film in but the wetting agent way does work. How about developing in the evening and hanging the film to dry when you are in bed? |
