      Thank you, sir.

      I'll get back on the ALBACORE job after I take care of some back-orders for Bob.

      Much good fun.

        I'm having a practice with the new gel coat. With any luck you'll have a new Beluga hull shortly (or you might have another pile of crap depending on how it goes).

          Excellent. Just give the lay-up a couple of days to transition from 'green' to 'hard' state before ripping the parts away from their tools. The big bug-a-bool with that first set of BALUGA hulls was the pin-holes in the finish and severe outward bowing of the two hull halves. Both problems should be addressed by improved lay-up methodology, and use of a proper gel-coat.

            In the last photograph, showing the various woven glass mats, is that last piece chopped strand? If it is, can you use that with epoxy resin? I thought that it was only for polyester.

              I've used it from day-one with epoxy -- the binder of the strands will 'melt' with either a polyester or epoxy chemistry.

                  Nice vid, Dave.

                  With regards to the chopped matt, there are two different kinds. The most common type has the strands bound with styrene, which melts down fine with polyester resins, but doesn't work with epoxy as it lacks the styrene content to emulsify with the matt. The second type is powder bound, and can be used with epoxy and polyester resins. The snag is that it tends to be more expensive and more difficult to find, plus it tends to come in more limited weights. I have limited experience working with epoxy, but have only used cloth reinforcement up until present with those resins.

                    Thanks, Andy. You're little water-tight camera enclosure made most of those u/w shots possible.

                    And thanks for the dope on the different matt strand binders. Guess I've just been lucky with the epoxy.

                      I'm glad it's found some utility. Were the shots with the camera fixed on the boat using the enclosure, or something else?

                        I used your camera enclosure for all towed or on-model shots. The perfect little item. You must go commercial with that thing!

                          That is such a beautiful boat. Seems to handle well too.

                            When I built those little pods, action cams were still a fairly expensive item, and choice was fairly limited. So making a case for the (relatively) inexpensive 808 made economic sense, and it also has some advantage with regard to good hydrodynamics being of streamlined form. Fast forward to present day and action cams are cheap as they come, and many are already waterproof or come bundled with watertight cases. Not streamlined, but not hard to make them so with some creative use of plasticard etc.

                              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                                Thanks, Tom. Maneuverability and speed was on a par with the 1/96 SKIPJACK.

                                Now to finish the work on Scott's little ALBACORE. It's such a joy to be working with pro's again.
