    Default amphibian with powerglide and transfer case

    open to suggestions on engineering and building an amphibious vehicle.posted some photos earlier, and now have photos of some hull progress. the hull idea is to allow air the enters the bow and rise up to hull bottom and be directed aft and out wheel well recesses that slope down and aft for lift at sides (full fender skirts may have small openings to allow water/air to escape) there will be strong small fairings in front of hanging A arms to redirect floatsum/ debris (hope to retract suspension) the power steering rack will be sealed and rubber booted ( small cofferdam sealed tubes) rear live axles have packing glands and rubber boots. the transfer case allows shifting power to jet and or differential.

    Since you're doing all of the work, I can throw out all kinds of crazy chit: How about air bags for the suspension? Rig the control arms with return (extension) springs or a torsion bar to pull them up into the wells after you vent the air bags to atmosphere.

    Looks like an interesting project. Planning on having a lot of time on your hands this winter?

    Also: Did you estimate the amount of water displacement (volume) you'll need with the hull to support the anticipated final weight of the vehicle?

    if you're gonna finish this, at least move those A-arm pivots up above the bottom. you can convert aluminum hydraulic cylinders to air and provide decent suspension and allow forced articulation.

    edit:

    and by ditching the powerglide & NP203 (205?) t-case and switching to an integrated t-case auto trans (AW4/NP231?) you can shed a shitload of weight. those cast iron t-cases weigh A L O T.

    An integrated Tcase means its bolted directly to the back of the transmision. 700r4 out of a K5 blazer has an integraged Tcase.

    Not sure an integrated unit would work in this case. It looks as though he's using what would normally be the output to the rear axle as the input, the output to the front axle to drive the rear axle, and the "input" to drive the jet drive.

    This guy's getting creative for sure. I totally appreciate that and I'd have been all over this project in my early 20's. It's the kinda shit I used to day dream about. Really great to see someone take action on something like this. People just don't regularly do that kinda stuff. Keep it up and keep us posted!

    good point! i hadn't taken that into consideration by the pics, driving the t-case backwards.
