I now think its for a mask along the lines of what you have said Tim.

I also take your point regarding preventing warpage.

I'm not building a complete new back PGK, just the moving part, the...

Now that's an interesting thought.

Interesting thoughts. I'm not sure it's any of them tho.

Eric, I would think it adds complications to making the back but I'm no camera maker.

Tim, I' can't see it holding anything. It's...

Hi guys

I want to make a couple of spring backs for my Gandolfi. Looking at three backs I have on other cameras, I see they all have grooves on the non moving part, (the actual back of the...

Thanks Vaughan. Amazing what you can get from Aliexpress!

Hi Graham, that sounds like a good solution, I'll look into it.

Maybe try and find a small engineering company near you and let them have a look?

Hi all

As the title says any ideas on how to develop half plate (6.5" x 4.75") film in a Jobo CPE2 plus? I've looked on 3D printing sites for a solution but can't find anything. While I can print...

Can you DM me with photos of exactly the parts you need, I might be able to help. I don't have all parts, only some.

That looks much nicer than my version!

Thanks for your input again Fred. The guys working on seem to have got the test pieces working fine.

You could have a go at making them if you can't find any suitable ones. I've made them from strip brass using a hacksaw, drill press, and files before. Brass is easy to work with.

So an update and a question. I spoke to someone who had been on one of my workshops who had mentioned 3D printing in conversation. I asked if he knew anyone in the 3D community who could model from...

That's a nice looking camera. Another source for bellows is a guy in Hong Kong who regularly has listings on eBay. I bought a set of bellows from him three years ago. They were for a Toyo Metal Field...

What you have a casket set or 'vade mecum'. These sets of lenses gave a large combination of focal lengths. They were generally quite slow. The longer the focal length the slower the lens. You might...

Very enjoyable documentary, thanks for sharing!

Here are two images of a stable door taken a few years apart. One is 8x10 (Burke and James) and the other 5x4 (MPP). They're both gum prints.

Church, Richford, Somerset, UK. Deardorff 8x10 with 5x7 reducing back. Can't remember the lens. Gum over platinum print.
This church was converted to a house. I nipped over a wall to take the shot...

Stunning work! 5x7 and half plate are my favourite sizes, I just love the dimensions. I don't care much for 5x4 and 8x10, too stubby for me so I sometimes guillotine my 10x8s!

Yes that’s my thinking. I sent a message to one person mid last week but not heard back yet.

The plastic bits on mine shattered and I know it’s happened to others as there was a warning (can’t remember where I read it) saying it’s prudent to remove the roller mechanism and pack it separately...

Fabulous, thanks Fred.

While looking for something in the depths of my backup hard drive I came across an old PDF from 2010 on how to attach a brass lens to a lens board. I've added it as a blog post which you can find...

Here's some photos Fred

Thanks

Oh the logical question is why don’t I just buy the 81-12. It’s overseas and I would save a stack on shipping and it’s also the wrong voltage for me in the U.K.

Hi everyone

Does anyone know if there is a difference between the plastic roller mechanism on the ends of the rollers with the 81-12 and 81-22? Mine broke during shipping (81-22) and I’ve got my...

I would do as you say. You could filter as well. I've done that and the salt solutions worked fine afterwards but I guess they are more dilute. With filtering precious metal salt solutions I use...

Fantastic, thanks Rich!

Hi All

I've finally found myself a Polaroid processor, tray, holder and a little film for a bargain price.

Does anyone have or know where I can find a Polaroid 81-22 processor manual? How is...

Thanks for your help gentlemen

Hi gang

I picked up a tripod head at a local auction for the princely sum of £10. On one of the arms, it has two 'things' (where my hand is in the photo) and I have no idea what on earth they...

Thank you Tracy. I now see that there are indeed two different Polaroid holders, one requires the tray and the other one doesn’t.

Hi all

I'm looking to shoot 8x10 Polaroids for a project but am confused with the hardware required. On the Polaroid website it mentions three options:

Option 1:
Polaroid 8X10 processor...

Ah Gandolfi, I wouldn't expect any less fom you! :)

John

A couple of good looking fellas there. The young one on the right just has the edge tho....

I would recommend googling images of wetplate holders, your bound to find something. To solve the problem of the T distance make two identical holders at the same time and putting the GG in one....

Thanks for your responses guys, you've given me good advice and ideas for things to think about and overcome if I take this route. I do have a couple of 10x12 cameras and a 12x15 to but they have no...

Thanks Randy and Roger. Yes Randy it not a reducing back I'm after rather an increasing back.

Hi Roger, I'm not looking for a Deardorff increasing back per se, I don't even know if one was made by...

Hi guys

Thanks for your responses. Just to be clear, I don't want you digging about looking for something that isn't what I'm after! The 10x12 back fits on the 8x10 camera by the four pins. It's...
