    Hello,

    I have cumpiano's book and in the process of building the guitar workboard with the cork guitar profile to raise the edges to accommodate the domed top.

    That being said, I also want to build a gobar deck. The ones I see online have a radius dish as a base. Could I use the cork outline here as well?

    Neither of my GoBar decks have a radiused base .
    The bases are flat .
    If you have radiused dishes , simply use them in the deck for glue ups .
    You certainly may use the cork setup , but do so with a flat base .
    Using the cork setup with a radiused base will mess things up .
    You can use simple gravity clamps for this as well .
    Gravity clamps are weights .

    I like that terminology, "gravity clamp." I'll use that.

    What is a gravity clamp? Is the gobar deck really worth building?

    A gravity clamp can vary in substance from a cement block to a piece of steel to an automobile to almost anything heavy enough to do the job .

    I've never seen the point of gobar decks. I've always been able to use clamps or weights for everything I needed and I sure don't need another big thing cluttering up my tiny (16 X 20) shop.

    Ask and you shall receive .

    Both decks with a few other things . Please note the additional sections of plywood for setting different heights above the base .
    A homemade setup using 1 3/4" plywood .

    Radius dishes . My decks are constructed specifically to allow for the use of these disks .
    [​IMG]
    Bars used in the decks . Since they are of a fixed length , it is necessary to be able to change the deck height for different processes .
    Hope this helps .

    My pleasure .
    A little plywood , pipe , threaded rod and fasteners and you are ready to go .
    There are plans on the internet that you can base a design on .

    If you are building flat-tops (not actually flat at all) then I think radius dishes and a go-bar deck are essential. Personally, I dome my tops to 25 ft. and my backs to 15 ft., which is pretty close to what Gibson did pre-WWII. I think trying to clamp braces is not a good idea, because the clamps exert a lot pressure in one spot, while go-bars spread the clamping pressure evenly across each brace. That's my 2 cents worth.
