    Hi Colin
    your questions have been covered many times on this forum, search a little and you will come up with a ton of info, i have also written about epoxy often.

    Firstly tell us a little more about yourself, where are you and what are you building, what experience have you with what - a little background info

    no no no

    our pine is lousy, might as well use paper mache or chip board - all bad

    building a 8m boat is a **** load of work

    free plans mean nothing - worse still there is very little backup in russian. i have checked and i worry about what i see, it makes me think of a clever designer that takes of like a rocket and when the money doesn't flow like a river there is no more backup or updates on the website, just a couple of grainy pics

    there is no point in using inferior materials

    First of all, it's much easier to read your post if it is not all caps.

    Building stocks, braces and other project related, but not part of the boat structure elements, do not need to be coated with anything, unless your project will take several years to complete, at which point paint will be fine.

    Elements going into a plywood boat should be encapsulated, not just coated with epoxy. That is every surface, every screw hole, every notch or cut out is coated with neat epoxy. If you assemble, then coat, some areas will not be completely covered, defeating the reason behind using this technique.

    Do not mix acetone with your epoxy, unless you have a chemical engineering degree, of which you can rely on, to support your alterations of the epoxy molecule.

    Colin where are you - town city dorp village ???

    i would like to know more about how you ulitimately see the build

    it is a very bold and "adventurous" step to build the russian boat
    dont get me wrong - i am not trying to knock you or the boat
    i went over the plans a couple of times and there are some tricky bits
    i dont think it is a simple build - its on the difficult side, precision will be important

    anyway go for it and enjoy

    germiston by the sea

    Morning manie

    live in a town called marlands thats in germiston.
    Was a bit concerned when i first saw plans but
    after studing am a lot happier about the build.
    Have very good wood working skills and am a
    qualified sparky and am pretty good all rounder.
    Haved received and downloaded tons of photos
    wich also eased my mind so let the fun begin.

    cheers colin
