    Micro extreme mono build

    While still sanding my Mystic 114 build, two other boats are in the works. One of them is a wee mono, that will be styled like the Lilly Extreme mono hull race boats.

    Got the hull plug made and mold cast. Transom shot, just to show profile. Note the lift-generating chine-strakes...

    Assembled the hull mold parts today, and sealed up the outside good. Now just to polish it and cast a test hull, to fab the deck & hatch plugs.

          Thank you for the praise. It takes it's toll though. Hands are knackered. Got a little bit of sanding on the Mystic. Work's gonna suck tomorrow.

          Polished up.

              Like skateboarding, practice practice practice.

              Here's a test hull to make the deck plug. I used 2-layers of 6oz. glass & epoxy. I'm happy with the stiffness.

                Mudded the deck today. The wood formers act a runners for the mud passes, so that two curves can be don at once, to make the convex surface. Glass was draped first, to save on mud usage. The shear wooden strips make a 90-deg area, where mud was formed into a radius along that area.

                  All faired. Graphite enriched resin coat, ripped off with 80grit.

                    Over-hung transom. Epifanes epoxy prime slathered on, and all faired out.

                      Tried a 2-layer 6oz. carbon battery tray, to see if there was significant difference beside cost. Yup. You can here the stiffness difference when you lightly drop them on a table. Also a 2gm difference in weight. Glass being 7gm. and the carbon being 5gm.

                        attachments did not work on this one, curious how you are doing your seams and or material overlap? i have done some carbon wok in the past but nothing for display or show purposes. i am just now getting back to it and going to have to learn to do layup myself.

                          Check out my mystic build, for the last way I did the hull/deck seams.

                          I have to wait till I have another hull and deck out the molds, and see which way to take. One of the reasons the transom will be seperate. So as I can possibly laminate the seam from the back, then do the transom.

                          We'll see...

                              More cowl.

                              Shaped, glassed, resined and primered. After fairing, it will be grafted onto the deck plug.
