    Oh, ****! Sorry, Andy.

    I should have recognized that barb as something only a subject of the Queen; a person residing in that evil, colonizing, Empire of the Kings would come up with. Such a vile suggestion is something a mild mannered, soft spoken, frog speaking, Denizen of the North American wilderness would never even think of issuing.

    My bad.

          I do hope that there is some play time on the horizon? All work and no play etc etc.

              Love the t assembly jig! You, sir, are amazing. Does the foam block need to be replaced frequently?
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                No. I've been using the less dense RenShape (20lbs. per cubic foot) for jigs and fixtures for years and never have needed to replace one, no matter how many cycles I put it through. Trick is, when employing heat (soldering in its many forms), is to put the holding elements well clear of the RenShape foundation. As illustrated with these two T-nipple assembly jigs.

                        Hello David,
                        I noticed in one of of your pictures that you wired up the twin motors in parallell but the polarities look like they're wired +/+ -/-, wouldn't the motors spin in the same direction when they should be counter-rotating?

                          If you're talking about the LPB motors, direction does not matter as a diaphragm pump matters not a bit what direction it turns -- discharge will always be discharge; suction will always be suction.

                            My mistake, I thought those were drive motors.
                            Carry on.

                              No problem, sir. I always appreciate a look-over of my work. Believe it or not, I occasionally screw things up and a helping hand is always appreciated.

                                Nothing to report the last few weeks, just the same old production work on SD's, and MSD's -- crap you've seen all too much of. But, Here's a delightful departure: proofing a RTR sub model for a friend.

                                He bought this 1/72 SKIPJACK r/c model from a guy who's been running it successfully for a few years. I took it to insure the new owner would have a trouble-free product when it finally gets into his hands.

                                Here's the model undergoing sea-trials at my Son's pool.



                                I enhanced the ballast sub-system on this models SubDriver through inclusion of a back-up gas type ballast blow bottle and blow valve. Most of the time the ballast tank is surfaced by use of the air-pump based SAS ballast sub-system. However, to insure the ballast tank can be emptied should the SAS fail, I included the gas back-up seen here.







                                Of course the added weight of the bottle and associated plumbing required retrimming the boat to insure it floats at the designed waterline in surface trim, and with only the top of the sail sticking out of the water in submerged trim.





                                Re-trimming is the process of playing with amounts and location of buoyant foam within the free-flooding spaces in the hull. Initially trial hunks of foam are rubber-banded to the outer hull for convenience until the boat assumes correct surfaced and submerged trim.

                                Ellie at work.
