Jim,

I was just thinking about this project of yours the other day. I'd go for the bathtub sea trial test too! A glass of whiskey, some quality smokes, bubbles, rubber duckies, candles maybe...the whole nine yards! I mean if your going to do it, why not do it?!? :D Rubber duckie....

Cheers,
Eric

P.S.
Did you feel the earthquake the other day? 8O

Okay. Slow going but I am moving forward. I’ve applied automotive body filler to the hull and I’ve started the sanding process. Maybe a little overkill but want this to be rock solid. Still have to add filler to the stern area underneath where the pink foam is visible. The rudders are good and solid and ready to be linked up to my two big servos. Steady as she goes!

Most years, Jim, up here it would need to be an ice boat around Christmas Day. This year is weird. :wtf: By this time most years I am driving the tractor around backward with the roll bar brushing low-hanging, snow-laden tree branches, perfectly aimed between the collar and hat, directly at the back of my neck. :O This year, I haven't even put the snow blower on the tractor. (Talk about pushing my luck...!) Nonetheless, look at those uncovered autumn leaves: just how far south of the Wisconsin/Flatlander state border are you?

Southern tip of Illinois. It was over 70 degrees on Christmas! Incredible.

What are you going to seal the Bondo with mate? That stuff is hydroscopic so won’t cope with extended periods of immersion.

More fiberglass cloth and two part resin. Learning as I go and all that. Hell, I probably should have left it alone after sheathing the hull with styrene and the first layer of fiberglass cloth. Oh well. :crazy:

I had to look up the definition for "Hydroscopy".

"Hydroscopy is the practice of viewing objects underwater".

Tank under water


Herman surely meant Hygroscopy: "Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment. This is achieved through either absorption or adsorption with the absorbing or adsorbing material becoming physically changed somewhat, by an increase in volume, stickiness, or other physical characteristic of the material, as water molecules become suspended between the material's molecules in the process.

According to CollisionRepairMag.com: "Talc in body filler is hygroscopic, meaning it readily absorbs water. Don't leave a vehicle in damp conditions with exposed body filler. Moisture could get absorbed and give you big problems later in the repair."

Thanks Herman. I did not know that. No wonder the repair i did on my Ford Maverick 76 as a student did not last one Canadian winter.

Yes that’s exactly it Mr Mcq11
I was very careless about the terminology sorry.
I learned the term from days of motorcycle racing.
Brake fluid not used of the grade I used was prone to attract moisture even through plastic containers,
Was advised to use fluid only from metal containers.

Anyway! Car filler is very prone to absorbing moisture !

Jim,

I spent from the 5th of December until the 24th in Wisconsin. It was supposed to be just an eight day visit, but my 86 year old Dad sprung a leak and was walking around one liter short of blood! Still doing woodworking, shoveling snow, and saying "I'm fine, just a little weak and tired, with a bit of damn dizziness"! 8O :/ Very stubborn German! So a trip to the ER, transfusion, multiple visits to the University Hospital in Madison for tests, etc., etc. He's doing fine now and it was good that I could stay to help them out.

At any rate, when I was up there I saw some guys out on Lake Wisconsin with a home made air boat. It had a hull that looks just like your gunboat! Definitely a "custom one off creation"! It appeared to be safer than venturing out on the thin ice to chase pike and panfish, though probably not by much. I'm not sure it passed the USCG inspections!

To our good Herr Dr.,

You must of missed out on the rain and wet 3 inches of snow that Baraboo got. I packed my tank up and took it along hoping to rumble through the long dead gardens, but there were only 2 days that were nice and I didn't get the chance to play outside with it. :( All of the rest of the days were so cold that I couldn't even feel the transmitter with my frozen fingers! To even have a cigar, I had to bundle up like a I was going out ice fishing for the entire day! I'd like to know what all of you native Wisconsinites BAC levels are!? I suspect a fairly high number! :haha: My Father is partial to nips of Asbach 8 year old German brandy. Yeah, I must be getting soft, but it's curious that once I quit drinking I quickly left the state! :think:

Anyhow Jim, your gunboat is coming along nicely! Carry on!

Cheers,
Eric.

Yes, I can hardly wait to catch a buzz from the fiberglass resin fumes! 8)

I'd recommend breathing very slowly and deeply! :shifty: Always remember to inhale...unless we're speaking cigars! :D

Cheers,
Eric.

I apologize for painstakingly slow progress but the hull now has two layers of marine epoxy/cloth layers covering body filler covering polyacrylic cloth covering styrene covering construction foam. Should be tough as hell! After some more sanding I’ll paint the hull black, install the running gear and begin the fun part of building the upper decks.
Anyone interested in 3D printing 13 42 pounder Civil War naval cannon barrels for me?

At this point I'd say not even an U-boat could sink that, man. Lol

I hope not, it’s going to be carrying a Beier board inside as precious cargo! Of course I’ll put it in a watertight compartment (not like Titanic’s) and will certainly need to attend a class or two at Rad University to get things adjusted correctly.

Jim,

Looks very nice! I'm surprised by the smoothness and contour that you achieved on the bow. But then knowing your work, I guess I shouldn't be! :crazy:

Cheers,
Eric.

Thanks, Eric! Good to hear from you my friend. I plan on making this a one of a kind rc Civil War gunboat. I know it’s not a tank but what the hell, it’s a sub forum on this site so I’m going for it.
