Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

[ic-racer]

the black "top" of my 1840 is ± 285cm wide. Wide enough for the posts. The top of my 2000 is ± 220 cm wide and has a connection for a ventilation hose. And has a App.Nr 98400377

I'll measure mine this afternoon and post it along with the serial number. I think I may have a later version. My black "top" on the CLS2000 has what looks like a factory installed plate where the hose would connect.

My CLS2000 has two fans inside the housing. Are there two fans inside your 2000? I read somewhere that the second fan on some 2000 heads attached outside the enlarger to the other end of the hose.

Just over the weekend I was focusing an 80mm lens on the Tripla for a 40" projection and there were no problems with the focusing rails going up to the top of the head.

Mine has 2 fans, one cooling the lamp, one cooling the mix box.

With the 1840 head my 1840 chassis maximum extension is 77 cm and minimum is ± 8 cm. With the 2000 head the minimum is ± 18 cm . All with a Vapla board.

How excellent to discover (thanks to a friend) this impressive thread. I have an ancient Durst 8 x 10 184 which I bought at an estate sale along with most of the accessories. It sat in our garage for 2 years, in pieces, while my husband and I debated the pros and cons of various places it could sit. In the end, 2 years ago, we built a new darkroom to accommodate it. Lucky me! Then it took time to get it moved in-all 400 pounds of it. Finally, getting it set up and ready to use took more time-trying to extrapolate my experience with my 35 mm enlarger to this situation.

The model you are discussing is newer and more complicated than mine. I do not have all the electrical gadgets nor a baseboard. But I am glad to have the links you provided earlier as I am now ready to start using this massive piece of equipment.
I am considering using it horizontally since the 360 lens I have on it, means that the easel is on the floor. Perhaps I need to consider a 300 lens in the future.

I would be glad to hear about any experiences you may have had using yours horizontally.
As well, there are 2 metal cylinders about 10 inches long and maybe 4 inches in diameter, that came with the Durst. At the moment, they are in the garage so I cannot post a photo, but I have no idea where they go, what they are for? Any ideas?
Thanks for any suggestions.

Glad to read that another Durst is being saved!

Yes, the 360 is not so good for vertical projection. The 300mm lens would be best. If your head does not go up all the way (because of a ceiling), then a 240 or 250 would also work.

Personally, if I were not doing enlargements larger than the baseboard (40" or so) then I'd look into those lenses for vertical projection.

There are a LOT of people on the Large Format forum that have experience with 8x10 enlargers, so if you have any questions or need help someone here would be able to help.
Can you post a picture of those metal cylinders?

Thanks for the info about the lenses. Kind of thought that might be an issue.
Will try to post a photo of the cylinders later today.
Glad to hear that there is lots of advice available. I had tried a source in Mississauga ON, thinking they might do a "darkroom call" to help me with it after it got moved. But they would not even give me a quote on a call so I knew I was on my own!
They did however, give advice over the phone and had some of the special glass to replace the cracked piece in the negative carrier and other useful items.
A friend and I figured out the settings because without the baseboard and motors that you have, it is an awkward process to do alone.
I have been contact printing up to this point so am looking forward to actually getting the Durst into action and learning to handle big paper.
Will look forward to future conversations.

Here are some pictures that may help. This is a CLS2000 S1441 80400353

Another option for you might be to get a HOTUB. It is deeper than the LARATUB.

Thanks for the pictures ! Mine does not have the D shaped holes in the top . My CLS 2000 was mounted on a 184 chassis maybe thats explains the difference. And my top hat also has a close fit on the rim. I have 2 HOTUB's but they are annoying to use. I like to change optics with different magnification. That is more practical on a tripla or unipla

Hello, the 8X10 is beautiful, can you help me design a head, make a head, find a head for my Durst 138 enlarger? I have a wire harness with halogen and dichroic filter. I have a glassless carrier too.

Cory, you could also go with a 240mm lens. Mine is a Schneider I got off of ebay. I have one on my 8x10 enlarger. Sorry, it's not a Durst...it's a bastardized copy camera from the graphics industry. I went with the 240, as my darkroom ceiling is only 9 feet.
