Tool to remove lens from lensboard?
Mike Jordan
whoever put the lens in the metal lensboard that it is in tightened the
holding frange tighter than I can undo with my hand. There are 3 slots on
the frange, so I assume that there is a tool available that can be used to
unscrew these. About how much do they cost and where can I find
one? Although I plan on just hand tighting them when I switch between
lens boards, if it isn't too expensive, I'd like to get one. Thanks for
any suggestions.

The lens wrench you are looking for is available from Calumet and most places that have large format stuff. There are two kinds one is adjustable and the other is a flat piece of metal with notches cut in the edges for the various sizes of retaining rings. I thought there were only two slots in the retaining ring? Anyway, I was taught to only tighten them by hand. I still have to use the wrench to get them off sometimes. As I recall the flat kind was $10 or $15.

is a spanner wrench. Adjustable spanner wrenches will do many optical
tasks like disassembling lenses. The cheaper alternative for just the
task of fastening shutters to lensboards is a piece of thick sheet metal
with slots cut, leaving projections at the correct separation for each
shutter size. These are made by Rodenstock and Toyo and cost something
like $10 or $15. The major retailers stock them. For this specific
task, I find the cheaper tool to work as well or better than an
expensive adjustable wrench, so don't think you are being cheap when you
buy this tool.

My experience is that if you want to avoid the shutter rotating on the
board, you have to at go beyond hand tightening and at least lightly use
the wrench.

professionaql camera store should have them.
It would be a better idea to find one lensboard that fits both cameras. The
most common waqy of doing this is to use Linhof Technika 45 lensboards and
Linhof adapters on the cameras. All pro cameras offer a Linhof adapter
board.

required. That involves using two mounting flanges rather than one
retainer. The flanges are affixed to the lensboards with screws and the
lens/shutter threads on and off by hand with no tools needed. See:
http://www.skgrimes.com/adapter/index.htm for a page about the difference
between flanges and retainers.
Retainers almost always have two slots or holes 180 degrees off from each
other.
I make and sell a very nice adjustable tool (fits all sizes) for use with
the usual style of shutter retainer. See:

There are several good options for lens spanners.
I own two:
1. One of Steve Grimes's excellent spanners, truly a delight and a
joy forever, but too large and bulky to go in the bag with the camera
and lenses.
2. One of the Rodenstock flat metal wrenches, with tabs spaced to
fit #0, #1, and #3 shutters.
Both do the job. Neither one is expensive. If you want something
to live in your toolbox, I'd highly recommend the Grimes spanner.
If you want something small and light to carry for emergencies,
the Rodenstock does nicely.

If you can't find a real lens wrench go to a bike shop, get an
adjustable spanner wrench. They look kinda like a small pair of tongs
made out of thin metal rods but instead of picking things up it has
small tips that will engage the notches on most lens retaining rings,
they are flexible so they fit a variety of different sizes. You will
have to hold it onto the rings or it can pop off and strip the
notches. I got one at REI Co-op for about 6 bucks. They are also
called pin spanners by some folks. Not a perfect solution but a
workable one, fits easily into a pocket in my back pack and it fits
this odd sized retaining ring on my Xenar 150mm lens.

I don't know if I could find a lens board that would fit both. One is a
Bush Pressman 4x5 and the other is a Brand 17 4x5 view camera. The lens
board from the Bush is smaller than the one for the Brand 17. I suppose a
lens board could be made that would allow me to set the Bush lens board in
it, but I'm not sure how I'd create one. What I plan on doing eventually
is get another lens to put on the view camera since I'll probably use that
more in my house to take portraits of our dogs... and the occasional stray
kid or two.
Thanks for the suggestion though. I've not thought of trying to find one
that could be used in both.

Thanks Paul. I'm going to check out Grimes spanners. I knew most of the
large format people had to have a source for these things. <grin>

I'll check the page out. This is a retaining ring as there are no screws

Thanks John. If I can't find one using any of the other suggestions I'll
take a look at one of the bigger bike shops in our area. We have a ton of
them around here.

Mike,
Just got one day before yesterday from a jeweler's supply house in
Philadelphia. $9.95
All metal, adjustable (small center worm gear), flat and easy to carry; and it
worked perfectly and easily.
Bonus: bright red/orange color so you can't mislay it.
