    Unicorn on the Ocean - 1120AF Coming to Canada

    Plodding along slowly wishing it was happening faster. Working on getting the chassis "ready" while procrastinating on the habitat decisions. But I think I'm getting close to deciding how I'm going to do that, on the basis that you work with what you know and what you can afford. Layout wise I...

    Ex army trucks - Are they worth it?

    Back on topic... When I was looking at trucks I went up to L Jackson to assess a Man 18.290 https://www.govsales.co.uk/index.php/search-results-by-description/50418-man-18-220-4x4-cargo-truck-with-twist-locks-and-tail-lift It had been on the lot a long time, and they wanted £42k for it. I...

    I don't know the full history, but it is either not enough air to hold the spring "off" on the park brake, a slow leak applying brakes on the service brake side, or something binding up inside the drum. I would use the test ports schreader valves on the top of the diff to start to try and solve...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Very slow and somewhat unsteady progress is being made. It's reaching a point where it's a little overwhelming, but after a few big decisions get made things will be better again. My dad had a suggestion for relocating the hydraulic tank so my box could be closer to the cab, It will sit between...

    Unicorn on the Ocean - 1120AF Coming to Canada

    A perfect analogy! I'm absolutely in agreement with you. And figuring this stuff out was why I did the test. The builders guide gives no options to forego a subframe on top of the chassis. Every suggestion they give, there's a subframe. So that would limit the flex to a degree, although many...

    Unicorn on the Ocean - 1120AF Coming to Canada

    I'd be interested to know the details of how you would do it again? How would you load/unload the wheel? Ours will be approximately 42" tall and 300lbs. Yes unfortunately there isn't room between cab and box, it's too narrow and there's a lot going on there. Hydraulic tank for winch, pass...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Yes it's certainly a valid suggestion, I think you mentioned that a little while back. I plan to stick to a rear mounted wheel for the following reasons. I am already maxing out the length of the body in terms of overhangs, and the logistics of getting a wheel in and out of a garage is much...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Thanks Neil, useful info. Yeah the 4 point pivoting style subframes, whilst I get their benefits, seem unfriendly for highway manners and not great for the frame unless you put them on a subframe above the rails. Limiting the sway seems sensible. I see your truck still has a subframe on top of...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Big day! I took her for a spin around the block, so much fun. The air system is working as it should, even the ABS does it's thing. All the indicator lights are still functional and I am super happy it didn't snap in half. While I was out and about, I thought I would test the chassis flex. I...

    Gotcha, I'll keep an eye on mine to avoid that expense! I'm thinking more of an internal valve leak as well, like a leak that slowly puts pressure into the service hoses without you knowing. If that makes sense. If the shoes are rubbing slightly I guess they'll clearance themselves eventually....

    You can (at least on mine) check pressure with a schrader valve for both service brake and the park brake air supplies right on top of the diff. Picture below, under a little black cap. The park brake release lines are the ones that go to both sides, and you'd be looking for the same pressure...

    Awesome update, thanks for sharing the adventures. It might be worth checking the air pressure on both the spring release and brake apply side of the rear. I know Jon had issues with his fronts slowly applying pressure because of a leaky valve slowly applying front brakes. Don't forget to...

    Unicorn on the Ocean - 1120AF Coming to Canada

    The translating was the hardest part of the guide, I did learn that the frames require a subframe on top of the frame so they're not well suited to just a 4 point pivot style without a subframe on top. That's what's helped convince me the sprung style is better suited for my build. Plus highway...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Just give me a call and I'll be there! I agree, it's so ridiculous it has to stay. It's so nicely made, with a pressure gauge in the cab telling me how hard I'm pulling. 80kn rated. It is capstan too so the speed and force is constant as it isn't winding wire on wire. It's a rotzler tr080, the...

    Unicorn on the Ocean - 1120AF Coming to Canada

    No opinions and thoughts absolutely welcome here! This truck had a 30kw AC generator on the back driven by the pto, I believe the pto output was 1:1 and the governor ran the engine at 1800rpm to achieve 60hz (European). I like your idea of using it like a charging alternator, I guess it could...

    Unicorn on the Ocean - 1120AF Coming to Canada

    It drives a hydraulic pump for a ridiculously overkill winch that came with the truck. It's 150ft of 5/8" cable and I really don't need it. But it's sooooo cool and I'm stupid enough to get very stuck... Pictures of the winch on some previous pages.

    Unicorn on the Ocean - 1120AF Coming to Canada

    Air system all roughly back together, I need to shorten a few more hoses and lengthen a couple more but it appears to be functioning just like before. Good thing I labelled everything, plus this has forced me to understand all the valves and how the system works which will come in handy in the...

    Unicorn on the Ocean - 1120AF Coming to Canada

    Great info, thank you. I'm moving my air control inboard up up, but perhaps that's even worse as the muffler exit would be upstream. I'll give it careful thought.

    Unicorn on the Ocean - 1120AF Coming to Canada

    What is everyone else running for departure angle? I'm going to take this places I absolutely shouldn't so I'm thinking 30 degrees would be pretty good. But I could gain a little more at the cost of living space with the usual 45 degrees on the back of the cab and smaller rear boxes. But it...
