    I have been reading Apug for a long time, so I've joined up.
    This year I completed building my first 6X7 film camera and also started processing C41 in my basement darkroom.

    I have been using K-mount 35mm since 1980, I have some Pentax digital cameras too, and a collection of Ricoh and Pentax -M slr bodies & lenses.
    I have a nice 1955 Graflex 4X5 Speed Graphic but I only use it with it's RH/8 6X9 rollfilm back because that is max for my darkroom tank,enlarger and scanner.
    I have a few Takumar 6X7 lenses but no body, and that is why I became interested in building metal camera bodies in my small workshop which has
    a lathe and an elementary x-y mill/drill. I also machine various lens adaptors and lens boards etc out of aluminum.

    This summer my rule was to "only use C41 film & nil digital" which I followed about 80% so far, and lately, with the new camera and my home developing methods improving,
    that has become "only use 120 C41 film" so I can focus on getting used to the camera and learning more about that format and C41.

    Those lenses don't have shutters, so a body for them would be a challenge

    Hello and welcome to APUG. I do some home machining, mostly part of my clock repair hobby.

    Welcome. A home machinist can be quite an asset to the site given our needs for various metal replacement parts, etc.

    Thanks for the replies!
    The first camera is based on the Takumar 6X7 90 mm leaf shutter.

    I am presently thinking and doing sketches etc for the second camera which will take the non shuttered Tak lenses.
    The retro focal ones ( 75mm and 55mm) have larger diameter rear elements.
    Last week I was lucky to find and purchase a Copal 495 which is a bare shutter with solenoid and an open diameter of 45 mm, for internal mounting.

    I am setting up a lens bench to hold the shutter and lenses, to measure the shutter speed etc. I am thinking to add electronic circuit board to time the shutter and maybe an extra solenoid to close it faster

    I will put up some photos and a description of the first camera in the Camera Building section.
    I will appreciate comments and suggestions for the next version.
