    That and if you look at the 3/4" ply under the spar it has the spar drawn on it.....I lay it down on the flat side....the back....and put the clamps on the one side....once those are tight I stand it up and add the clamps to the other side.
    Vintage wood is the BEST! But....every now and then a plastic missile can be quite enjoyable!

    So......building right along....
    Brown came thru and dropped off my steel for the joiner...



    I cut all the 1/16" ply shear webs for the outside front of both spars...



    This is what is left from a 12" x 48" sheet of plywood!

    My pile of "clamps"....



    All "clamped" and ready for me tomorrow to do the other side!

    Again, THAT is a lot of spar! Nice job on estimating the plywood, by the way

    Ohhh, we've correlated the carbon wrap to the prevention of tip stall now.... Awesome!

    The epoxy spread on the plate rather than in a Taco Bell 64 oz cup might be a good thing to 'splain.

    Ah....the ol'why is it better to mix epoxy in a thin state rather then in a cup....well...you see.....I just like green plates!
    No....not really....I mean I do like green plates but that's not the reason. Epoxy while in its liquid form is best kept as thin as possible to kep it's "kick" time as long as possible. As soon as you mix epoxy it starts to chemically react which produces heat as a by product....the more heat the faster the cure....the thicker the liquid epoxy the faster it heats up and the faster it "kicks". So, by keeping it as thin as possible you allow for the longest working time of the epoxy.
