    tifosi12! Start from scratch, research, learn, experiment, and then build on! You will get it if you WORK at it! As your success's grow, so will you a long with your enthusiasm! Sorry for the rant guys! Just my take on this wonderful hobby we have! Thank you Bob Martin, David M. SUB Ed, just to mention many that have helped me (and are still helping me) along the way!!!!
    Actually I love the unchartered path and finding out stuff and learning. To be totally honest, that's why I stopped with tanks: Once you've built one as a kit, the rest are similar, so I developed my own. I love that part. What frustrates me to no end is that there are vendors out there (not including Bob of course) who sell stuff or as Dave called it a stinking pile of xXXX knowing full well it won't work. That's disappointing. And Arkmodel is not the only ones who have done that. I had other bad experiences in Asia as well as in Europe.

    And just for the record: I have a successful surface runner and one so-so capable of diving. Now I want to build one that static dives without an asterisk or excuses. I'm pretty sure I'll get there eventually. As Ringo said: With a little bit of help from my friends.

    Once I have a fully working static diver I'll move on to develop my own. As my boss once told me: Ideas are easy, implementation is hard. I'm full of ideas. :)

      Excellent. Your credentials are extensive and will serve you well. Send me pictures of the 1/72 Type-7 rudder mechanism -- maybe we can work out the rudder throw problem and get that boat into running shape for you.

      Since I retired from the SD business Bob is working his best to finalize his own version and will only put those up for sale once he's confident he has a reasonably priced, well working product -- as his standard of business demands. I'm sure one of his first SD's will be a two-shaft version sized for that beautiful bigger Type-7 kit.

      But that's water under the bridge -- after clobbering three expensive hull kits you've likely soured on that project. However, that SD will find application in the soon to be released 1/96 STURGEON GRP kit Bob will be selling mid-year. May I recommend that to you?

      You want a running boat by regatta time. Which will it be, sir?

      Actually after my first attempt with the XXIII I built a rig even you'd been proud of (see picture). Problem was that the hull of the boat is so think, it starts to flex and warp once the Dremel cutter puts pressure on it. Then the cut is no longer a perfect line. My other issue was that the little plastic sticks you made for the fittings kit didn't stick to the boat. I used a gazillion ton of Krazy glue and Epoxy and made them stick somewhat but that was still no clean way to mount the top part. That said your other parts from the fittings kit were excellent, I got the dive planes and the prop to work just fine but could never cleanly close that hull. So yes, that's an abandoned mine at this point.

      So I'm using your Caswell WTC for Ota's 1/12 Seehund. Fingers crossed. I'm in the honeymoon phase of a new sub project. Haven't reached the 7th year itch yet.

      As for your kind offer regarding the 1/72 Type VII. Yes, I'd love to get some input from you for that. My feeling is that its a bit of a lost case at this point. I think I drilled too big of a hole for one of the rudder anchors and that's why it is unstable. And honestly once I get the 1/48 Type VII to run, my interest in the smaller boat will likely be eclipsed. It was my first boat and I learned a ton. I don't even know whether I'd be willing to take it as is to Carmel. People would probably just laugh at me and it.

        Nice work with the cutter! From what I am hearing, you my friend are well on your way! Great attitude!!

          David's fittings kit are usually molded in polyurethane resin. Did you remember to "wash off " any residual mold release agent a wax that can interfere with the adhesives? With my Kilo fittings I initially soaked them in some lacquer thinner followed by vigorous brushing with a toothbrush followed by hot soapy water to remove the mold release.
          Make it simple, make strong, make it work!

              I edited them a couple of times as I tend to make typos along the way. Apparently if you edit too many times you're a spammer. Nice.

              Maybe the one who shall not be named can release my posts as non SPAM please? Not that they are greater than Shakespeare, but...
              Giving me Moderator authority in a forum is akin to handing a loaded, chambered, and cocked semi-auto .45 to a two-year-old.

              Better I not have such awesome, terrible power at my trembling finger-tips. Let Bob wield the sharp knife in these here parts.

                I hear you. I'm actually a mod on a different forum and even if you know what you're doing, it's often a pain in the you know what to keep things and users under control.

                  Of course not. :) Thanks for hint. Water under the bridge now, but good to know for future endeavours.

                    Thanks a lot. I'm on my way alright. Let's see how far it will lead me this time. In general I have a positive feeling and feel confident enough for the stuff I know. It's the unknown unknows which will get me every time. For instance I just discovered that different PLA colors and manufacturers react differently when being CYano glued together. Didn't see that one coming, thought PLA is PLA. Well it ain't.

                      YES! Not only the gluing aspect, but the actual printing as well! The colored Solutech filament that I used before my new Dremel would not extrude as well as the white! Experimented a lot with temps.to get it to extrude properly. I am using Dremel filaments with my new machine this time around!

                        I found that Solutech white PLA is the easiest to glue together. For just regular 3d printing my fav brand is Hatchbox and of those the easiest to deal with PLA is their "wood".

                        Solutech green PLA is the worst ever. Brittle like crazy, breaks just feeding it into the printer.
