    Question on how to fix the lens board plate

    While I'm trying to replace some parts on my Calumet 400, I noticed a problem with the top lens board plate. One of the drilled holes where the board is suppose to screw into looks like it has been damaged.

    Seems maybe someone tried using a larger screw that was not original. Anyway after ordering a new plate and screws from Calumet the one screw keeps falling out because it is too small. Ideally I would like to some how fix this so I could use the original screws intended.

    One idea I thought of was soldering the old hole, and then redrilling it.

    Is there any other way I could possibly solve this problem?

    (I know I could try using a larger screw, and did try this with some things I had around, but it didn't work too well)

    Regards,
    Martin

    There is a product made by Loktite that is a two part metal epoxy (metalic resin and hardner) that will allow you to create new threads using the correct screw. It is found at most hardware stores (I found it at Ace Hardware)
    Art is a step from what is obvious and well-known toward what is arcane and concealed.

    Thanks for the advice... I'll look around for it at the stores and see how it works.

    There's also a glue called liquid metal, forgot the manufacturers name but it is also a two component glue. Pretty much all two component epoxy glues will work. I just finished an alloy board for an 11.5" Aldis with a retaining ring made of epoxy glue. Wraped some teflon tape from the Hardware store around the lens, put the lens in the board, applied the glue in a liberate layer around the thread, let it harden. Unscrewed the lens, remove the tape and voila, you have a thread glued on to the alloy lens board.
