    System Three expxy experiences?

    A year ago or so, I made some fish boards which I and my colleagues use to measure fish. Despite using 6-7 coats of Spar urethane, I experienced dramatic swelling and warping when using the board to measure about 400 fish a day. The board remains wet for 10-13 hrs a day while in use. One of my volunteers had made a wooden boat out of plywood and swears by System Three epoxy finishes. I just whipped out another fish board and am going to finish it with that epoxy as a trial. I did read on another woodworking board that it will seal wooden vases to make them waterproof. If that is really true, it opens up some new possibilities that I'd not thought of.

    Does anyone have any experience with this line of products??

    I've never heard of it Jim, but I'd love to hear about your experience with it.
    Keep us posted...
    I especially like the idea of waterproofing vases and bowls....

      Jim:
      I have used System 3 epoxy as a glue and found that it performs as they claim in terms of mixing, application and curing. However I have no experience with it in a wet environment.

      For your application perhaps you would do better to use something other than wood, for example, polyethylene. You can get various sizes of polyethylene cutting boards at your favorite kitchen supply store, or even at Walmart. It cuts as easily as wood, although the shavings have a LOT of static cling!

      Good luck,

        Jim -- In researching this product, I found several links that give me hope for good waterproof results. One is www.woodturningonline.com/Turning/Turning_content/epoxy_for_woodturning.pdf
        Another is a discussion of epoxy finishes at Waterproofing the inside of a turned vase? [Archive] - AAW Forums

        I picked up some System Three at Woodcraft and hope to get a first coat on today. I'll post results in about 4 weeks after I put it to the test in the canyon and see how it holds up in the field.

          Frenchy -- I embed (route & flush mount) a 600 mm (approx. 24 inches) metric ruler in the boards. I haven't seen any poly rulers. Metal rulers would heat up in the direct sun and I fear could harm the fish.

            Jim, the concept is to totally encapsulate the board in epoxy and seal all sides and ends. May want to have more than one layer to ensure. Being a former sailboater I am familiar with the concept and it works well. Embedding a wooden ruler should also work well.

              Jim I would suggest a thin coat of epoxy resin over the ruler first as a sealer and then glue it into the the rebate with epoxy glue and then finish across the top with further epoxy coats.

              Good luck,

              Rhys
