Calumet 8X10 with Dagor 10 3/4 in. f6.8

Take my word for it, a tripod will present itself from a most unlikely place, soon after you buy the camera outfit.

I will post a picture later today. I am a little familiar with simple repairs on a few lenses. I recently took apart a Hasselblad 80mm to see if the main spring was broken and manage to put it back together with the help of a Youtube video. I also have been fixing copiers and printers for over 40 years and have many times removed assemblies without the aid of a service manual. The biggest obstacle to fixing anything is knowing how it's supposed to work. Once you know what is supposed to happen most repairs are straight forward. With that being said I will probably screw this one up just to teach me a lesson.
 
I apologize, I stated the lens has Left hand threads, it does not, it has Right hand threads. Turn to the left to loosen, right to tighten.
The lens is likely from the 1960's and possibly the shutter also. A rubber jar opening aid or a strap wrench may be helpful.
 
Here are the pics. It appears to have two holes for a spanner but it didn't want to move, but I didn't use all my force. I applied lighter fluid with a Q-tip around the edges and it freed it up a little for a few seconds, so I just think it's gummed up and taking the ring off and cleaning it should work.

If the speed cam is gummed up like that... so is everything else.

Please don’t...
 
Set the speed dial to T, aperture to 6.8, shutter released. This is the starting point when disassembling any shutter. Note the position of the speed indicator. Throw the lighter fluid away and get some 90% Isopropyl Alcohol.
Apply some nail polish remover between the chrome ring and shutter collar, let sit 5 to 10 minutes, use a blunt tip spanner in the indents in the chrome ring and turn counter clockwise. Count the number of turns needed to remove the ring.
Lift the face plate off the shutter then if necessary lift the speed ring off after taking a picture of it on the shutter.
 
Ok I am to the point that I can lift the speed ring off but before I do are there any cams or springs going to fall out or off their correct position when I lift the ring off?
Here is what I bought for $321 including tax because of the shutter ring binding.

Fall out or go “sproooing”... not really.

Fall out of position... all of those slots have an “arm” that fits into it. Doublecheck that they are in place as you replace the speed cam ring. Otherwise you could bend or jam.
 
That looks like a good buy to me!
 
I removed the ring and cleaned it up but if I tighten the locking collar down it binds the ring so I backed off about a 1/2 to 3/4 turn and it's much better. All the speeds seem to be fine. Now that I have the camera, where do I start? I have a contact printing frame, timer and a safe light, but I need to get 8x10 trays and film. Any suggestions for first time 8x10 user on film. What about x-ray?
 
Why not take the money you saved on the kit and have the shutter professionally cleaned lubed and adjusted. It will be done right and you will eliminated the possibility of you screwing it up. Save your receipt and you will probably get all you spent on the CLA if you sell it. Bill "Support Your Local Camera Repairman" Barber
 
Oh, the film holders come close to being wort what you paid for the kit. Bill Barber

Buy some film, chemicals, and trays if you want to do tray processing. Clean the film holders with Windex and lint free towels. Load the film holders in total darkness, set up the test scene/still life, focus and compose on the gg, insert the film holder, set the exposure, cock the shutter, pull the darkslide, trip the shutter, insert the darkslide, repeat for the other side of the holder if loaded with film.
Process the film in total darkness. You will find a cable release an asset otherwise tripping the shutter by hand may induce vibration resulting in unsharp exposures.

I did 8x18 for a while. I converted a Jobo print tank to a film tank and used it to process 2 sheets of film at a time. The film will lock between two large ribs on the inside of the tank while the smaller ones keep the back of the film from touching the sides of the tank. It makes daylight processing easy with a manual roller base. I'll part with the tank as I no longer use it.

Ding, ding, ding... we have a winner of an idea!
 
I don't want to spend the money on the cleaning yet. I want to see if I will even want to pursue 8x10 further. If I thought the speeds were way off I would send it out to be cleaned.

hello campy51
down the road from you in providence and waaawrick there are 2 repair houses
that are extremely well versed in your shutter and cleaning it
if you want to scratch that itch be careful of putting lighter fluid in there
some shutters need to be run DRY and lighter fluid screws them up...
you might search ( here on this site ) surveyors tripods
you can get them for cheeps and modify them to work with your camera ..
and film is extremely expensive for lf cameras, unless you use
xray film! or paper negatives
good luck !

Would this work and what would I have to get to modify it?

Well your significant other won't like the holes and scratches left by the spiked feet but the big problem is the 5/8-11 mount thread and the hand truck to move the tripod about. Cameras have either 1/4 - 20 or 3/8 - 16 threads. The camera mount can't be increased so you will have to reduce the 5/8-11 or replace it, likely easier said than done.
 
Thanks
