If you could have a part made, what would it be?

Haven't you ever come about a situation and said, "Now why doesn't

someone make ...."? Maybe it's a little part, or a whole new thing.

 

For example, I wondered how it might be to put some composite 12"

wheels on a tall backpack frame so that I could pull it on easy

terrain. I built it, and it's very handy!

 

Someone asked in another forum if there were long-exposure devices

to attach to a lens or cable extension. Yes, there is the usual

spendy Prontor (which has a particular liablity) but an electric

timer of the same size could be made rather reasonably.

 

Then of course, there's the weightless sky-hook tripod. :)

 

Any Wish List items you might like to have made?

It's not LF, but I would like the shutter link for the Argus C4/44 cameras. There are many of these cameras useless for the want of this part.

I always thought a wheel made of differing filter materials mounted near the mount of a

camera would be handy. Just compose thru a skylight-rotate a particular filter into place and

voila'.

All the time Pico

 

Getting late but I will get back tomorrow

 

Great question

Gary, I have seen such gizmos, but largely in mopix work. Have you ever seen those several inch-long, vertical stepped filters that slide down in front of a lens as you make a longish exposure? It used to be demonstrated in color shots of waterfalls. Talk about a niche, eh?

 

Lee, I especially look forward to your post.

 

Yes. It's late.

Later.

ys mount for pentax K mount

I have 4 ys lenses 2 are ordinary( a zoom and a 135) and 2 are better ( 18mm and 85mm)lenses but not affordable for pentax.

it would be faurly easy to do.

graft a pentax K T mount onto a ys mount, possibly pentax m42.

8x10 Readyloads. Filmholders are heavy.

That's why I have a lathe and mill, so I don't have to say, "If I could only...".

I'd make a retaining flange for your SA 210/8.

Lathes and Mills can only go so far, you need a personal fabricator like a stereolitography machine. Instant (almost) gratification.

The one I always think about is why my $50 cable release with the tapered threads always falls out of (and sometimes strips) the 50 cent release block on my $1200 lens! Other manufacturers, like Nikon, use a non-tapered cable release screw on their bodies, but there should have been a better standard for LF format lenses LONG ago!

Hey, Tom: I returned the lens with the suggestion to use a hose clamp and rubber buffer. :)

 

Michael: I feel your pain! I've collected dozens of releases over the years and when I find one that fits well, I leave it in the lens shutter. :) And look for another.

 

Linhof got it right, but not robust in their quick (mumble, mumble) release thingie.

I happened to stock up on the proper tooling to make American style straight threaded cable

releases.<p>I wanted to see if it was true that they're no longer available before I went ahead

with this project.<p>Tapered cable releases don't fit American straight threaded sockets very

well, such as on almost all Copal shutters, by the way, or vice versa.<p>Look at the variation

in these Euro cable release tips;<div></div>

Once an American (straight threaded) cable release is screwed into a shutter with a straight

cable release socket, it stays screwed in.<p>That could be the last thing that saves your lens

before it hits the ground when you forget to use the slide locks. If you use a Euro (tapered)

cable release in a straight socket, it could unscrew from the shutter in a quarter of a turn.<div></div>

Compur shutters have tapered cable release sockets.<p>Copal shutters need straight cable

releases, not tapered ones.<div></div>

There used to be these tapered to straight threaded cable release adapters.<p>You could

screw them onto your tapered cable release, and use it in your straight threaded cable

release socket.<p>I still have a few.<div></div>

Noah, I gather you are a machinist. My deepest respects. And in all these years I never saw those cable end adapters. Most excellent information. Thanks very much.

Most of the drawings of Copal shutters show straight threads. Looking at my Copal shutters, I find that some of them have straight threads, others tapered-threaded sockets. I can't find any pattern: neither age, nor lens manufacturer. My experience is that standard releases with tapered threads engage fine in the Copal shutters with straight threads; yes, I know that it is inelegant.

 

 

Someone is making an adapter to convert from sockets with the old American-style straight threads to the tapered threads: http://www.representatives.com/3d/special_stereo_realist_cable_release_adapter.htm. There have been posts asking for cable releases with longer throws for older shutters such as some Ilexes; having straight threads would go with this application.

don't recall exactly ( i remember too much old stuff)

there was a suggestion in an old book that you take

a " valve core wrench-type tire valve cap and carefully cut and file and file the projection off and use a 6-32 tap to thread the remaining hole.

this makes a "leica to straight" cable release adapter.

I recall trying this as I had some kind of old camera with

threads around the base of a smooth ( unthreaded button) shutter release.

it fit and wirked.

Hi Pico, very interesting and detailed information above.

 

I'd like someone to manufacture and supply in kit form all the hardware minus the wood.

 

Cheers.
