    Hey whatever works!

    Good luck over there in the land of a thousand-islands, pal.

Its looks so radical that I just can't resist it. I also found a place that sells 1mm square ceramic files. Here: http://www.ottofrei.com/Ceramic-Fibe...llar-1mm-x-1mm Looks like I'll be able to file out those little drain holes after all, which is lucky because nothing else worked. Incidently the same crowd used tio make a 1 x 1 mm steel needle file that sold for $67.00 a pop. Strangely they have discontinued it!
      Thanks, Scott, they're shaping up nicely. Yeah, more pitch -- more like what is observed in the photos of the real thing.





      I found out what I did wrong on the first attempt: when I positioned the first blade to the hub I used the wrong radius point wedge to angle the blade to the hub. What a dumb-ass!





      The replacement wheel has the correct pitch. People may ask why so much more pitch to the after propeller than the one ahead of it. It's because the swirl from the forward propeller presents a lower effective angle of attack flow to the after propeller. So, the after propeller has to have a substantially higher blade angle in order to act like a propeller which has the same pitch as the one ahead of it. The object of the game is to have both propellers of equal relative pitch.

      I'm with you, Scott. I'm going with that science-fiction looking original ten-foot spacing of the two wheels. Did it with Skip's 1/60 ALBACORE, might as well do it on your 1/96 ALBACORE:





      Thanks for the tip on those ceramic square-files. Neat!

              So how do you turn a dome like the hatches are? I got one ugly chatter marked piece then I tried.
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                It's all about a tight head-stock, tool-holder, and tail-stock; RPM's; feed speed; and tool height above/below center. There are charts for materials to guide you as to feed-speed, but I find experience to be the best teacher here.



                If things chatter, change the chucks RPM. If it keeps up, reduce your feed speed. If you still can't get away from resonance chatter take up knitting!

                    Wow! How on earth did you bend that wire so accurately? Those hatches look great. And in other news; the resin has finally arrived. I'll go and pick it up tomorrow. Hurrah!

                      I assume you mean the spiral-wound 'hatch spring'? If so: I simply wrapped some copper wire around a small diameter mandrel. Nothing to it.

                      Great news on the gel-coat. Get hot!

                        What's that gadget and what does it do?
                        Make it simple, make strong, make it work!

                          A pre-loaded torsional spring. Without it the hatch would be almost impossible to open.

                                This is the first production hull for the Albacore. The gel coat is made by a company here in Australia called Technirez and I have to say that it really works. Who would have thought that using correct tools, correctly would result in a better job!
