Jobo 3062 Expert drum for 11X14 special production

For a while now we have been trying to get Jobo to make some 3062 Expert drums for 11X14 for us. Until now this has been a bit of a problem due to a specific missing part. We have recently found a small stock of this part and can now have the drums made.

As there will be a limited amount available, and this will be some what of a "special order" production run of this unique drum, i wanted to gauge the interest, and also offer first dibs on these drums to the LFPF community.
Right now we are looking at making 15 units, and will start making a tentative "pre order list" for those who are interested.

The lid cam have either the light trap funnel OR beaker (your choice)

The projected price for this drum will be 485$

Done!

I will be interested if you can come up with a drum like 3005 for 1114 film. I mean five sheets per load.

4 would probably be more of an option, based on circumference of the folded sheets and 3000 series tank size.

Stone: the drum is a print/film drum, with two sheets being loaded at a time.

koh303: Will the little inserts to keep the film off the drum be available?

I know, I own the 2500 series one, but the other poster was talking about the 3005/3010 style, so I was saying if they designed one like those it would be 4 sheets not 5 (probably).

I am working on the possibility of making Custom inserts for the 3062 to carry one 11X14 sheet of film, it's in early planning stages but i will update when it moves forward.
Due to the small batch, and intense manual labor in making it, the cost for the insert would most likely be close to the cost of the drum, something like 350-375$ making the whole kit quite expensive.

For now, we want to concentrate on getting the drums made, then we can move on to the next step... :)

For reference: old eBay auction, drum with insert.

Why would the insert be so expensive? If it's labor intensive to produce, could it be sold as a kit?
(Yes, I realize that the drums need to be discussed first, but the reason that I am motivated to buy one is for 11x14 film.)

They do come up rarely used, and this one sold for a great price. Even if we sold the insert with the drum as a kit, it would not change the price that much, other then perhaps save a bit on shipping.
As you said Brian, for now we are trying to get the drum project off the ground, then we can start to look at the insert.

The special production 3062 drums have just landed, for all those of you who showed interest - please contact us ASAP, as there is a VERY limited quantity of these available.

The final price for these has matched fairly closely to the original price projection and is available for 495$ + shipping.
Will post some photos tomorrow.

Your Web page for this item

http://www.catlabs.info/product/jobo...11-x11-35x45cm

is in error. It incorrectly states that the maximum film/print size a 3062 can handle is 11x11 inches. Should be 11x14 inches. The centimeter data seem correct, however.

Thanks Sal, corrected now.

The idea mentioned above to create an expert drum that could take ULF film sizes is a great idea. Say 4 sheets of 11x14 at a time, or 3 sheets of 14x17. It gets old quick having to develop a single sheet of 14x17 in a 2500 style long skinny drum.

the diameter of the drum is fixed. The diameter of tube for 11" or 14" film is fixed. 3 tubes for 11x14 would be a tight fit that would even work. If the tank allowed for water bath between the tubes, it would fry your jobo circuitry from all the weight.

We can dream can't we? I guess you are sadly right. Just the weight of the developer alone - about 800ml per 14x17 sheet - would likely fry the circuits let alone the weight of the drum. 11x14 might work though if it was limited to 3 sheets - it would probably need only a little more chemistry than the five sheet 8x10 drums.


Perhaps Jobo can give us a reason to upgrade with the CPP5 with a beaffier motor and deeper bath for large drums?

The 3063 will do two 11x14's so that's something to think about.

The 14x17's are rough, but it's all B&W so allowing for a tempering bath inside the drum isn't as necessary. So tubes COULD work and not add weight, but JOBO won't take that risk for such a small run, unfortunately.

I have brought this up several times.
There are other concerns - such as the strength of the lift arm and brackets in light of a potentially heavier drum. All of these components were designed before the first inner tube style expert drums were invented, and so all of this is unknown though the general word was - it will never work.

With that said i see no reason not to offer it for off machine/magnet drive use. Selling them on something new and unproven is hard at best. It is a tiny market, and R&D costs would be very high.

How about the redesign a stronger lift, that's the worst part is the design IMO, it's cheap and upgrading that would significantly improve things and would take the least amount of actual designing, just needs to not be made entirely of plastic and should have been upgraded when the expert drums were made.

This is my opinion of course, but I doubt many would disagree with me that the lift is a shoddy design at best when working with any expert drum, and even some of the linger 2500 series drums.

If it worked properly you wouldn't have to lift the other end with your hand.
