    Neil: No, the blades give a lot, and have stayed strong for several years now (I finished the camera in December 2009). The amount of flex needed to insert and remove a filmholder is really not a lot; the film holders might bend them an additional 1/2" more? (I use plastic Lisco Regal 8x10 holders).

    Holder inserted - see the total bend on the hacksaw blade; not much!

    Thanks, Rafael.

    The only springs I have to hand are some an engineering friend made for me from spring steel; I believe he softened them to work the material and then retempered them. I'm about to start a new 5x4 and it looks like hacksaw blades are a good thought, then.

    Rafael, that's a very ingenious solution to locking the back to the frame! Iw ill ave to give it some serious thought on my camera. Thanks for sharing those pictures. Looks great!

    Sorry for reviving am old thread but I am considering using feeler gauge for my 5x12 camera back. I would like to know if you had to heat the gauge before forming?

    Annealing, forming, and retempering feeler gauge material sounds risky unless one has plenty of experience. I'd rather grind down the teeth on an old quality hacksaw blade and use its mounting hole in one end to improvise a clamp that restricts movement of the ground glass frame parallel to the spring.

    Regular sheet stainless accepts folds, drills readily with a carbide drill, and small strip pieces are in stock in many hardware and hobby shops...
