    just want to double check, the neodymium magnet between the solenoids isn't going to mess with anything in the gun control?

    or is it far enough away? (just double checked and it's between the mags)

    We couldn't try this in Treaty, all barrels must run parallel in a single turret.

    same in Fastgun. the ATL has two dual purpose five inch turrets on either side of the superstructure. so those guns will be in each of those two wing turrets

    Started on the electronics. This boat is going to have five boards, the Rx, the motor ESC, the pump ESC, a trigger board, and a BEC 5V power supply. First step was to solder wires onto the boards that needed them (motor ESC and trigger boards) and then waterproof with E6000.

    BC trigger board coated in E6000

    I take my heat management seriously so I super glued some aluminum strips to the FET's on both ESC's. The top board is the Robot Power Wasp 30A multi-directional ESC for the drive. The bottom is a modded Hobby King 20A unidirectional ESC that will drive the pump.

    Some freehand 3D printing! I gooped hotmelt glue into the recesses between the aluminum and board to beef up the assembly.

    Next comes wiring and connectors

    Been awhile since updating this thread but I have been getting stuff built.


    Lots of 2mm gold plated bullet connectors have been getting soldered. FYI, I like to twist my power runs together to cut down on radio interference.

    upload_2018-1-22_8-20-15.png


    These bits are going to be the power distribution assembly. I'm using a gold plated RCA jack and grounding plug as an externally accessible power cutoff.

    upload_2018-1-22_8-20-40.png


    The bits assembled. This gets bolted to the subdeck and the removable plug sticks up through the deck.

    upload_2018-1-22_8-21-53.png


    These are doubled up 2mm female connectors on each leg of the drive ESC motor wires...

    upload_2018-1-22_8-22-55.png


    ... and how it gets plugged up in the boat. One ESC will be driving both motors.

    upload_2018-1-22_8-25-0.png


    To tap into the Lowes Kobalt power tool battery, I came up with this connector. Some copper scavenged from an old water pipe and bits of FG sheet and glue.

    upload_2018-1-22_8-26-8.png


    Battery connector installed. I'm using tinned and stranded 16 gauge wire throughout but I wanted to beef up the wiring a bit from the battery to the distro assembly so that's why you see it doubled up in some areas.

    upload_2018-1-22_8-27-31.png


    Before I started installing wiring I wanted to cut the hull windows first. I clamped it down, setup dust collection, and went to town with my oscillating cutter...

    upload_2018-1-22_8-28-45.png


    ... that is until this happened. FG one, hardened steel blade zero. Need to get a diamond blade to finish this up.

    upload_2018-1-22_8-31-13.png


    Since I couldn't cut anymore for the day I finished filed what I did cut to the appropriate widths.

    upload_2018-1-22_8-32-33.png


    That's it for now. It's off to HF to get a diamond blade for the cutter.

    love the wiring setup for the motors. what's the plan for a failed drive motor? would you be able to swap any of them out easily? If not, I am thinking of using a modified version of what you have with spade terminals to attach them to the motor like Nick has on his Derfflinger

    Unbolt the shaft and the motors pop right out. I'll have spares in the box.

    Window cutting continues. I burned out my last blade so I picked up this 2.5" carbide cutter at HF. I was going to get the diamond cutter but I noted that the carbide grit on this cutter is brazed on instead of epoxied with the diamond cutter. Thought it would be more durable and so far is working great.

    This cutter cuts wider so your turning more material into dust. One nice thing with the oscillating cutters is that the dust tends to stay right next to the cut so the vacuum gets most of it.

    upload_2018-1-25_9-24-24.png


    Since the cutter is round it's tough to get all the way into a corner. A thin metal file makes quick work of cutting the corners out.

    My weekends have been filled up with other projects so I've been cutting a window or two before work during the week. Almost done with starboard side!

    Other projects and travel over the past few weeks have taken me away from the Atlanta but my schedule is clearing up and I actually had a couple of hours to work on it yesterday. Got the rudder built! :)

    I can't believe I haven't seen this earlier. Steve, that's a very interesting weapons arrangement you've got there. Seems reminiscent of Big Gun torpedo-cruiser setups. Was that part of your inspiration?

    The long horizontal holes that Charley's aft 15 degree offset sterns on his Seydlitz left in my Barham were the inspiration!
