Paul,

That's a fantastic idea. You'd even have electronic timing.

Looks like everything would come apart with simple hand tools. Not sure about the bellows, though.

And yes, the large knobs are probably aluminum.

Why are you planning to do this? A nice one...

Equinox Photographic advertises a stock of retaining rings. Nice folks to deal with, too.

Polaroid made passport cameras (actually, subbed them out to Cambo) that had a vertical center divider and two 125 mm f/8 lenses. It gave you two photos at the same time on 4x5. They had a standard...

In Jerome, AZ, I found out the hard way that ziplock freezer bags aren't watertight. I was using them to store film in a cooler that was about a third full of ice & water. Luckily I only lost 20 or...

Jim,

I like your examples. Now I guess I'll have to knock out a lensboard and get shooting.

Did you try to add stops, or just shoot it wide open?

Thanks, David

A projector lens makes sense. Mine looks a little like the one in the search results, so that's probably it.

Guess we'll see how it works for taking photos. Didn't cost much, so I don't mind.

I picked up an old brass lens recently that has no markings at all beyond "Enterprise" engraved on the focusing mount. It barely covers 4x5, and is around 6" focal length. The focusing mount has...

You can camp at the KOA in MidPines for very cheap. It's about forty miles to the west. Nice folks, hot showers and no worries about bears tearing up your car and all your gear. There's a nice...

Got my B&J Orbit 8x10 (a rebadged Calumet C1) for $300 not long ago with BuyItNow. Stuff's around if you look hard enough.

J & C sells some tubes:

They look like they were originally used for transporting rolled blueprints, so I bet they could be found...

I believe I've read that the Dallmeyer Pentac lenses are the same design. I have a military surplus version that was very reasonable.

S.K. Grimes could probably make some bushings for it. You should call & ask them for an estimate. It might be cheaper to look around for another lens that has ugly glass but a good shutter.

And...

Polaroid offered some two-lens ID cameras in 4x5 awhile back. They subcontracted these out to Cambo, who built them around the back section of their Cambo Wide. I got mine at auction for $100 or...

And the ground-glass panel w/viewing hood is 14 oz by itself.

According to my Ikea kitchen scale, a Crown Graphic with top rangefinder & flash bracket, but no lens or board, is 4 lb, 14 oz.

The original lensboard & Wollensak 135 adds 7 oz.

I've picked up an old 5x7 Rapid Rectilinear and a Voigtlander 135 Skopar that were each $35 or so, in shutters, via eBay. No, the speeds aren't great, but they do work. And the glass on both is...

I've got that exact lens & shutter combo, and got it back from Carol recently. She does excellent work. I'm sure you'll be in good hands.

John,

Thanks for the update. The "1/4 watt" tells me it's a neon bulb. Even if GE doesn't make them, I bet a few will still turn up. I might try the dollar store, small local hardware store,...

Just read some recent posts on photo.net. Dude's definitely off his meds. Get a Crown Graphic or a medium format rangefinder instead.

Ken,

The Festival bulb with the threaded (medium) base is normal in the USA for household use; the others are commercial. I got mine from eBay for $25 plus shipping. Let me know if you need the...

John K. - Any chance you'd have a part # for those GE lamps? I've checked their site, but come up empty-handed.

Thanks, David

Go to Photo.net and search on this topic. You'll find out all you need to know about Mr. Littman.

There's no way I'd buy anything from him.

Can you make a reducing adapter board to something smaller?

Here's an essay that might be helpful:

Michael Reichmann has spent a lot of time researching and writing about...

Sad but true. My local photo store in Baltimore carries a fair selection of B&W film, probably because there's an art school nearby. I buy all I think I'll need before I leave town, though. ...

Since the repro lenses come in barrels (and later leave them for shutters), I'll bet these aren't worth a lot. There's probably more than a few around that folks haven't bothered to sell. Maybe...

Mine's an Orbit, and I can't find any differences.

Here's a similar project:

Good luck!

Here's another vote for a Majestic geared head. Mine came with a nice large plate so you an attach the C1 at multiple locations.

Folding the film leader into a tiny "W" (or "M") simplifies loading the Leica M. You shove the crimped part up into the takeup spool, and the tulip on the bottom plate does the rest. This isn't...

Try Artography Labs at 410.467.5575.

They do nice work; not sure about handling it via mail.

Call Lens & Repro and ask about used 8x10 film holders. I got some older wooden ones from them recently for $10 each. One or two of the holders I got just needed to be retaped; otherwise they were...

How about a cooler (ice chest) with plywood inserts to hold the rail? Coolers are cheap, and some of them have wheels.

Dave - The one I've got is about an inch across the front, 5/16 across the rear, and fits into a half-inch hole. The center tube has a long threaded section to adapt to different door thicknesses. ...

Dave - I've got one of those door viewers here. They're very wide angle, but they will work. Also, you can swap the elements around inside to get a small change in the angle of view. The front of...

Bob - Would a lens manufacturer have different aperture scales printed for multiple possible focal lengths, or would they use the average (published) focal length? Just wondering.

Jerry - You can...

Next time around, you can use the JB Kwik product. Half as strong, but that's still 1800 psi. It sets up solid in four hours. Wish I'd heard about it sooner.

You're gonna love it.
