Anybody using one of these for 4X5 film processing?

The processor is made of Acrylic, which is a brittle material, and if cold it can break when dropped, unfortunately at the moment this is the most affordable way to manufacture the unit.

I'll concur that manufacturing out of extruded plastic would drive the cost up significantly for small production runs. I checked on making one like that several years ago based on the Phototherm molds, and to get the cost down to the prices Morgan can sell his unit would have required a production run of about 5000 units. Which would have meant 4800 units would probably wind up in the scrap heap when I die. Making a run of only 500 units would have put the price at several hundred dollars each. No one would pay that much.

I think that's the beauty of Morgan's device, it does a good job of balancing costs against convenience in a device that can be manufactured in quantities that the LF market can support.

Sure you could do better with an unlimited budget, but if we all had unlimited budgets we'd probably all have our own personal N2 burst line.

Hey Chris,

I just processed 60 sheets today and had no problems, no jumping or touching. That was 320 tri-x in R09 (Rodinal equiv.) 1+25 20 Degrees 8.5 mins, inverting 1/min.

What film are you using and what chemicals? Would be interesting to know.

I'm assuming that your using it in the Paterson tank and have the black inner tube in?

I've made a new video to update my technique and did a test showing it. I'll post it later.

Cheers,

Morgan.
 
HC-110 B, TXP320 (what are the odds?) and Delta 100. It was a mixed bag, to test reversal speeds. Developed for about 12 minutes; agitation might've been excessive.

And yes, the tube was in.

I look forward to the video, and I have a feeling that my inversions were just a bit too "he-man". I'll be sure to report back though.

best!
 
Hey All,

So i did this little video to demonstrate how i use the processor, a bit of an update on the last vid. It also shows what happens if you really give it a good shake.

Hope it helps,

Let me know,

Morgan.

What a coincidence!!!
I bought that Paterson Multi-Reel 3 and i never used yet even once, i was hoping to develop 2 120 films at once but i always end up developing only one roll, but now with that MOD-processoer, i feel i will have a big use for this Paterson 3 Tank, i have Combi-Plan and BTZS, bought them just as a spare and before they can be discontinued, but i didn't use any of them, that Combi plan seems bad if i will develop only 1-2 sheets for 1L of chemicals, but if i will develop 6 at once then this will be handy, i use 1L to develop 2 120 rolls, and about BTZS i still don't understand the videos uploaded, it is like it is shortened and deleted more details, i am not that American or English person who can understand a video of 5-10minutes, let's say the most thing i care about for BTZS is how much chemicals i need to use for 4x5 and also how can change chemicals if in daylight or dim light without fogging the film, i may not be as quick as it should be then to have the risk to corrupt things, so i didn't use that BTZS as well, now this MOD-Processor looks like so tempting and way easier than the other two because i got used to use tanks all the time, changing to another processor types may not help me how to do it properly.
 
Morgan,

Good video instructions on the "proper" way to use the processor. The first time I used it, I pretty much made a mess of things - thought it would be the same as 35mm or 120. However, lately, using a "gentle" inversion, I've successfully processed my last batches of film.

I still believe that your processor is a great invention and gives us Newbees to the world of large format the means to develop our film without the need of sending it out to a lab.

Never mind just the newbies. This device is probably one of the neatest things I've ever seen for 4x5 film processing. If I didn't already have an HP CombiPlan tank and actually processed enough 4x5 film to justify the cost, I'd be all over that thing like white on rice.
 
8x10

I haven't read this entire thread which is now quite long. But I wonder about an 8x10 version that could fit in a Jobo 2000 series drum or something commonly available.

It would us a lot of chemistry, but with 3005 drums fetching >$500 an alternative might be compelling.
 
Thank you Morgan,

mine arrived in fine shape and works very well, HIGHLY RECOMMENDED.
 
I don't know where i lost my Paterson 3 reel tank, but once i will find it i will order that MOD tool
 
Any chance of a 5x7 version?
 
I also use one of these, and I find it to be much easier to load than the HP Combiplan holder. I have discovered that very gentle agitation is an absolute necessity for using this holder in the Patterson tank. I agitated a little bit to vigorously and had a sheet of film get ruined as it had several areas where the emulsion was scraped off. I have done very gentle agitation since then, and I have not had any problems since then.

Thank You Morgan for making these processors. I have put mine to good use by processing 12 sheets of 4x5 sheet film every week for a photography class that I am taking this quarter.

Hey Daniel,

Glad your getting the hang of the processor, yeah you have to use gentle agitations.

All the best,

Morgan.

Hey Jerold,

Doesn't really work in a rotary processor, but perhaps in the future.

All the best,

Morgan.
 
sorry to bump this old thread. i would be testing my mod54 soon. i would like to ask if there are some people who had other techniques that would like to share using this processor. :smile: i've seen morgan video already. looking for other alternatives. actually i would be using this processor to an old paterson system 4 tank (not the super which is required). i just added some mods so i could use it properly with my old 3 reel paterson tank. what i added is a tube i cut from film canister to the top of the processor so it would not move or wiggle inside when invertion method is used. i made two tubes actually. the other one would be possible to use the twizzle stick rather than doing invertion.. i will try the twizzle stick first since my tank leaks a lot of water when i tested it in invertion method. i will try both and see which would work best for me. i will try to post result as soon as possible.
