    Wow, Kevin is using 3d printed parts instead of wood!
    This is a new age! ;):D

    I know, I'll probably start typing about my vast battle experience instead of attending events, boat reliability will tank, and then I'll show up to battles with a box of 3d printed parts instead of a boat. Really a troubling development.

    In actuality, the prospect of making two shipsets of everything pushed me over the edge, and I'm sticking to little things I can use on my other boats

    Mid-day update
    Printed some battery holders

    This will be for Agincourt and others in future

    Also working on gun mounts. I’ve seen this style on several top captains’ boats

    Clean routing
    594D91E6-CE93-429D-95DC-56757D59787A.jpeg
    Plan is to epoxy the elbow holder, then use E6000 to attach to underside of deck
    62A3E778-5AAE-42BC-8E4D-B21E9E1F10DF.jpeg
    Turrets staged with deck coated in epoxy

    Plan is to continue on gun mounts

    Worked on pump mounts today. E6000-Ed on gun holders
    B6DB17C3-8E58-4ED6-93E9-8F82FF46BBD2.jpeg
    My standard pump holder, space was kind of tight, marking holes on hull here
    4C060630-CF14-4A88-8F9D-356E12D09D6E.jpeg
    Dry fit, clearance from deck
    136DED2A-F8D3-413A-96E7-473D768B5B0F.jpeg
    Line was for deck cross member that I should have put further forward
    86B93C45-316C-42CA-A8E4-ED41CF25D622.jpeg
    Pump can be slid aft between sorties to clear screen, held by hose
    FA9EC994-FB7F-4DC4-BC7A-9C10F8345AA0.jpeg
    Will glue in over next few days

    Glued gun mounts in, cradle came out in a good spot
    84A5DE3A-7B0D-4320-828E-1179A4A20F76.jpeg
    Forward guns, pretty straight mags
    DAF5502D-AA69-4AA0-AC1D-391AFB20F99D.jpeg
    Bow gun
    28F74FF5-994F-4802-91FF-ED6A35632DB6.jpeg
    Duals, cradle just clears deck rim (intentionally)
    0437D0E4-6E09-4C33-9FC0-6B7D6C6ABB86.jpeg
    Turret fits on with no issue
    D009B9CD-D095-4A75-893D-672C8D3FB619.jpeg
    Full set of guns in number 9, need to bend mags for number 1 but all mounts are in place
    C5D3194E-22BF-4306-9BCD-7C276FFB3CE9.jpeg
    Glued pump mount in with e6000 since I didn’t have need for a full batch of west systems
    87C49205-1796-4F4C-A637-033D012F1E27.jpeg
    In other hull
    71FEA1EE-4B5A-4E66-9E23-069EAABA5484.jpeg
    Glued bottle mount in, need to start wrapping up the smaller jobs than are mostly complete
    5BA5715C-5883-4D26-85AD-7BA77041EF8E.jpeg
    Next up is mags for hull 1, then probably internal armor before I start installing internals. Also gathering a big order from BC. I’m thinking of just using two 15Ah cylinder cells to power the whole thing, typically I use note batteries but I think those will be sufficient. Weight is looking good too, one of the boats was 12.5lbs with motors, guns, bottle, batt. Should be able to decide what final weight will be more so than other builds

    Thanks Jeff

    An hour or so of work today bending mags for hull 1
    5A6A0AEE-16E0-4716-A6C1-4513E05CAEB0.jpeg
    Hull 1 is near
    C84E1BCA-5943-4795-8177-29196CFCFBA3.jpeg
    And forward, mirror images
    C422AD45-DA75-484B-A13C-692BF2ED8745.jpeg
    Will need some slight tweaking to get angles right. Should be able to get them to hit where I want
    BACB76CC-C772-45DB-B148-230DF11F8583.jpeg
    Sterns are same because of pump outlet
    30B1ED1F-7654-4C77-B6D0-DF8FF489B9AE.jpeg
    Turrets
    A1CE62B0-C080-4C2F-A15B-4EFFCA9480C0.jpeg
    I call the overall gun layout the ‘porcupine’

    Internal armor next, also finishing stuff for guns (barrel holders, magnets, set T height, air T. Once internal armor is in I will start installing stuff and shift to CO2/ electronics.

    Armor today, pet resistant dog screen, works real nice
    5F2409D3-EC66-4C74-9756-31277362F714.jpeg
    Cut to size, then gooped to deck rim (top edge is folded over flush with underside of deck rim, goop every 3-4 inches, used some hot glue to minimize clamp usage)
    F94184A1-5A1B-4012-844E-19E87835E771.jpeg
    68CC63F1-F718-4ACB-9EB5-9F09DC55482B.jpeg
    Won’t impede water going into the hull, very effective at stopping bb's (don't listen to keyboard jockeys that might say otherwise, though it should be just as effective on the shelf as it is in battle)
    75AE9275-FC12-48D8-9F04-04E167E3200C.jpeg
    Repeat on other hull, will do the other sides over next few days hopefully. Once I had one piece cut, I traced it 3 more times for use on other side/hull
    3AA7E622-EEC2-4E40-8DED-265FF9D23E2A.jpeg
    Also gooped on gun magnets. I like goop here over e6000 because of how much e6000 runs, can gum up the threads without careful drying orientation. I CA the magnets on first, then goop edges and over the face, works pretty well. Place magnets slightly below center to prevent rip guns

    Goop retains elasticity longer than ec6000. And doesn't shrink as much over time.
    I've used both to install prop tubes and motor mounts on my cruisers
    Also it's easier to say

    Side 2 done tonight
    AC4D8F44-05CC-487F-87DC-7C01BFBB637A.jpeg
    Gun magnets came out good (enough)
    E5B1A2D9-2BAA-4882-8D32-C24FADC27632.jpeg
    Next step on guns is set the T height, reinstall, make up CO2 hoses and barrel holders. Next on boat will be installing running gear, solenoid mounts, planning electronic placements

    Working on odds and ends. Clippard parts showed up, happy with what I could find to minimize the number of fittings required for the duals, good volume/size. Check valve with female inlet and male outlet, 1” tank of better dimensions than brass version
    0274D6D4-F337-4B58-8343-831390ECEF0E.jpeg
    Also making little T fittings for gun hoses. Start with 1/4” square brass. Drill holes while piece is whole
    0432EA9C-FE47-4DC6-93F8-88E022307F3F.jpeg
    Tapped prop holes and flat spot on shaft, SS 6-32 set screws, red lock tight because I care about the props haha
    3D99EE06-112C-4F8D-BF80-3A82B540911A.jpeg
    Props drying
    1CEC7644-BFDF-49E9-B856-89E5D33FAAF2.jpeg
    Blades seem less directional than prop shop (rip) Korts so Cant really put them on backwards
    3DC799D6-3912-4C51-9155-05ECFB68852F.jpeg
    Parts for T’s all cut up ready to go
    E8D0A210-A98D-4328-B311-6D359B96D60A.jpeg
    Solder on one side is good enough, flows through
    FF565D8F-3754-44EF-9EB9-991AB90555B0.jpeg
    Drilled through first tube to connect the middle tube
    0CD3DB63-8E6D-41E0-BC29-B2C6E5B8A99F.jpeg
    Now middle tube
    58090B51-8F8F-4302-972C-A09F1DBB32EE.jpeg
    Ran out of butane so TBC.
    Once middle tube is in I’ll drill through tubes with 1/16” drill bit to clear out any solder that gets in there.

    Set T height, piston drilled earlier and spring. check for free movement
    B8EDDF06-9F7C-4125-B90F-2966C4E5F189.jpeg
    Screw the bottom cap up so piston blocks bb from mag
    21CC27ED-B572-4516-8E2C-27543C051F95.jpeg
    Put bb in, slowly unscrew bottom cap, moving piston down until bb slides on top of piston. Can see BB on top of piston. By using the compression fittings it makes testing the piston height much easier, magnet helps too, but can use gravity if no magnet. Can also test fire before sealing with glue, but I've done this enough that there are generally no issues come test fire time
    560A4820-345E-48BC-B0F7-5E8478CC949A.jpeg
    seal the cap in place with CA, full coverage

    1F89B6EC-1CAB-4AAD-903B-35AB93729892.jpeg
    Worked on gun barrel holders from aluminum. I used to not use them, but barrels get knocked around in battle, also need it to keep the bow guns at 15 degrees
    D78C8510-B05D-4AD7-966E-260511615F2A.jpeg
    Aft sidemount, 6-32 screw through deck, will be epoxied in place
    220CF160-3B31-45AD-8BF0-00F81536873A.jpeg

    Bow gun, need to get creative based on the narrow deck and A turret but I think it turned out OK
    B578BF72-3665-4FF0-AA49-0B3D2869D2E1.jpeg
    Right on 15 degrees. Should hit the WL about an inch or two aft of the stem which was the desired location
    0D745837-B3C4-4F2F-8230-0D1143C08930.jpeg
    Duals, also had to get creative. Ran into interference with the magazine holders under the deck, but made it work. Checking the trajectory so BBs cross at point of hitting water, this point is probably 4 inches aft of stem for the angled attacks
    3CE6C5B5-CB40-4864-BE46-E10420F009E8.jpeg
    15 as well, holder should keep it legal
    2E276564-0472-44D8-8082-29B4E3D9858E.jpeg
    Hull 1 duals. Still need to cut down the excess threads and epoxy them in once I have enough other things to use up a batch
    35728148-9FEA-45B8-8748-D491F1282CE1.jpeg
    Running out of things to do, waiting for a pretty big order from BC with solenoids and electronics for both. Maybe sheet over the weekend

    Thanks Nate, they are coming together well. Sheeting work was taking longer than planned yesterday at Marty's, so I switched to making gun pistons. Some parts from BC and others showed up so I'll have some things to do on the internals that will keep me busy for a bit. Today I epoxied the gun hold down screws and the turrets. Added a layer of cloth on some surfaces of turrets to increase BB resistance, my boats don't live on the shelf haha

    Almost 15 lbs, max around 20. No electronics or superstructure, but will probably need to add 2ish pounds
    EA9B0F46-05CB-4F62-A76C-4ACE07289A43.jpeg
    Balance not terrible. On a small level seen at the step. This would be bow heavy as the center of floatation is about 1” aft of step. Should be within ability of trim weights to correct

    Bottle is turned around compote originally planned. Still assessing, forward solenoids with tanks are in outboards

    I would like to keep the BC integrated board and ESC aft of batteries to minimize wiring runs. It should work out Ok

    Planning to give arrangement a shot on hull 1, then will re-evaluate for hull 9 before I make stuff ‘permanent’

    A model for all other Courbet's to be judged by. Wonderful work. I like your expansion tanks, very simple, optimized. I've been making 2" long by 1/2 diameter copper pipe expansion tanks and soldering 1/8 npt male/male connectors on the ends to go straight from check valve to tank to solenoid, but yours is very clean and no soldering required.

    Funny you mention that it was a little bow heavy. The real life Courbet's were also, the french engineerings apparently didn't fully account for the weight of the superfiring forward turret.
