    What are you guys using for jigs when building smaller boats say 14'-18' fishing boats that have ribs and not the big frame work to hold it in place during manufacturing!

    hoytedow I'm not a cat.

    Methods vary according to materials used and hull type. Please be more specific.

    The method determines the type of jig, or if you even need one.

    If you are using "ribs" than why do you need jigs?
    Stringer should keep your ribs in place.

    You're absolutely correct, as do laminated ones.

    I erroneously assumed he meant to hold the planks.

    It just goes to show you, doesn't it?

    I think he needs to narrow the question. Also, we all assumed he is asking about wooden boats.

    Im going to assume since this is in the metal boats section hes asking about metal boats

    Aluminum moves alot when being welded so typically anything that can be done to hold things "true" will help. Boats on the larger end of your scale frequently use a metal frame which the bottom is bolted to in various places prior to welding.

    I cant help you with suggestions for a riveted hull as I am not very familiar with their fabrication.

    More details on your end may help get better answers here
