Machinist in the house?

This is not quite OT. From the Repair Filter thread it is clear that many
of you have machine-shop experience. I have made a prototype camera using
wood (cherry) and would like to make the next protoype in a material that
is more stable, stronger and can be cut and shaped using woodworking
tools. If you can nudge me in the right direction, offline if it is
appropriate, I would be quite greatful.

Now when they say it machines just like wood do they mean soft pine or the
worst tropical wood? I think the stuff is fairly common and you should be
able to find it.

Medium format? or sheet film? Toyo makes plastic view and field cameras;
quite reasonable in price, relatively. Now a focal plane shutter with a real
flapping mirror would be interesting.

LF - 4x5 sheet film, and this camera has an unconventional design so I see
no cluses by looking to what has been made. This camera is not even
similar to anything already made. For example, there are no flat parts as
in a box-type camera. No lens board, no movements, either, and it is very
heavy so I really do need to use something other than wood.

Thanks, Nick. I did not find that in my search. In return I will share the
folllowing link, although it gives me more choices than I know what to do
with. http://www.plastic-materials.com/

Two of the sources are right here in Minnesota.

Yes, as you suggested, some wood is very hard. If it cuts like Cherry I
would be happy. If it cuts like Ebony, I'd be as well off using steel.

Thank you again.

how about the cambo passport camera case and 4x5" back? take off the 4
lens front and septa, and you have a plastic 4x5" shell with back, simply
mount your lens in front. D. Fletcher mounted a 65mm super angulon on it;
is this for your monster 75mm biogon? ;-0) see photos of Dirk's wide cambo

I appreciate the tip, Bob, but that's far from the design objective of
this particular camera. I saw this:
http://members.aol.com/dkfletcher/widecamera.jpg but that idea doesn't
work with my lens, which is much too large to be supported by a lens
board. You also recall the 4x5 WA I built several years ago at
http://WIND.WINONA.EDU/~stafford/sandwich-4x5 which is similar to your
idea, but won't work. (Say, would you mind taking that page and putting it
on your server instead of just linking to it? I am losing my server any
day now.)

Some time ago I posted a rejected design he
http://wind.winona.edu/~stafford/WA-75.JPG

That's a modified Printex 4x5 body. A bad idea. Rejected. The body is
totally unneccessary in this project for a number of good reasons.

Delrin or nylon...you can buy sheets from MSC-Direct.com

Thanks, George. I have a lot to learn of these materials, so I'll start
with what has been recommended and study up. Thank you, all!

You mentioned that your camera hardly has any flat surfaces. So I
think it will take numerical controlled (NC or CNC) machines to
manufacture your design. There are quite a few machine shops which do
not manufacture any devices but only components for other companies,
and they will be happy to receive such an order because it will bring
them some money. Manufacturing components on CNC equipment usually
starts on several hundred USD/EUR, with no upper limit. Among
engineers, there is a saying that 'gold plating a prototype does not
add much to its cost'.

However, I would suggest to consult the yellow pages of the next major
city.
