    Ok cool, I did pretty much that, but with a likely inferior tape.

    See how she turned out. the timing for the rudder rule change was right when I ripped out the shafts, so I'm gonna get the most out of both now.
    Hopefully this'll cure the Puking-Dog Turning radius problem!

    Will be printing remaining turrets and barbs tomorrow, benefits of work from home. Once those are in I’ll make up and mount guns

    Printer was banging away most of the day. Same mounting setup as Kongo, magnets in turret and barb

    always like getting barbs and turrets staged

    Had to pull spacing in based on turret shape

    forward barbs, relatively quick change from Kongo files

    I like the way the turrets came out, large turrets are convenient
    35706090-9244-4650-A847-DC62BFE01EDC.jpeg

    Next step is gluing barbs in

    Haven’t been able to spend much time working on the boat, but I have been getting the SS printed. Used the files on this site, modified to reduce plastic and for ease of printing. Hopefully will get to spend some time actually working soon

    Gun making time
    704A5D62-0560-4567-9EFB-3FBABE3671FC.jpeg
    replenished inventory recently, making guns at about $8 cost each

    Everything soldered up

    next step will be magazine bending and mounting

    Played around with gun magazine routing, then decided to drop some components in to see how the balance and weight

    stern mags look like they will snake together down the Port side to avoid the stack of two solenoids on Starboard side
    FFE46667-1F3D-49CC-9EA2-9972ECBA3961.jpeg
    Filled her up, most of the SS printed
    02A8A8DB-3A38-4CBE-9D6C-4EDF6DF5973A.jpeg
    balance point at 32.5" from the bow (WL level), just about right
    B3E745E0-627D-4C4B-A3D2-B9CDCE9C975A.jpeg
    25 lbs 1 oz - about 4-5 lbs below target weight, but that weight will disappear quickly
    D5F14D2A-F447-46B4-B9F6-E0BC5F9F8096.jpeg
    Funny how these boats fill up quickly. The 3rd pack might have to go depending on how the weight works out
    7462D9B2-E7CE-4B47-99D6-DD21C23BDBBF.jpeg
    Next will be more magazine bending, printing up mag mounts, checking gun hose routing and solenoid mounts

    looking good, with everything so close to the sides are you going to have room to mount the inner armor mesh to protect all those goodies.

    Yup, no concerns about that, this boat will probably have more space than most of mine between components and internal armor - the pet-resistant dog screen has held up great on all my boats

    I have a question about those LiFePo4 M cells - how do you charge them? I mean, are they semi-permanently connected, with additional wiring between cells (I think I can see extra wires coming from the terminals) to allow balance charging, or do you unscrew all the cells and charge them separately each time?

    They are wired as a 2s pack with the appropriate balance lead. They connect to the charger the same way any multi-cell lithium pack does. The terminals are coated in tool dip to prevent shorts, and they would only be disassembled if one cell died or a balance lead broke and needed re-soldering. I only balance charge occasionally because I keep the depth of discharge below any value of concern. Some other captains wire them up all individually which works too - many ways to skin the cat. The 2s 15Ah packs work well across all of my capital ships, with the larger ships having multiple packs wired in series, parallel, or a combination of both as needed

    What you use for the mold to pot your ESC? Can you reuse the mold?

    Previously I had a simple frame glued to a scrap piece of plywood that I put wax paper in to use as the potting form, now I just print up a box because it’s easier
