    any particular reason for the leaf spring choice up front? what springs are they? I would think a better approach angle would be a goal.
    any closeups of the rear axle/spring mount?

    If you think about what it would look like with bigger tires the approach angle isn't so bad. Sure would feel weird to wheel that close to the front of a rig. /forums/images/graemlins/thinking.gif

    I really like the wheel chock.

    /forums/images/graemlins/peace.gif

    Sorry. Upon further review it was determined that the wheel chock in question is not in fact a steering wheel but apparently a rock ring of some sort. A steering wheel used as a wheel chock is much funnier than an apparent rock ring.

    Much apologies to the general public for the lack of humor.

    2 reasons.... cheaper - ...and I had them laying around!
    Remember that the reason for building this buggy is to prove this nutty drivetrain concept. So I wanted to get it going in a quick/inexpensive way - and these stock Wrangler leaves looked to be just the ticket! /forums/images/graemlins/waytogo.gif

    This is as close as I've got. But there's nothing fancy on the spring mounts. The eye of the spring mounts directly (no shackle) to the axle. So the 1/4 el spring serves double duty as upper links and springs. The front of my FunBuggy is pretty much the same.

    Wow, one rear shock??? Where did you come up with a crazy idea like that /forums/images/graemlins/thinking.gif

    You aren't worried of axle wrap/flex steer? I would see the rear end moving a lot since your upper links are basically getting shorter as they droop due to the arc of the spring. I realize if you used a double wrap spring it would combat the axle wrap issue but it will also severly hinder the flex in such a light weight set up. Either way I like the out of the box approach and can't wait to see it on the trail. It will probablt be a lot easier to tow too.

    Looks good. Only thing that scares me is thinking of you sitting in it while winching and haveing the cable break. Nothing there to keep it from hitting you. /forums/images/graemlins/yikes.gif

    This is a good point...
    Gonna use nylon rope. And gonna make a shield. The rope is pretty "user friendly" if it breaks - it doesn't "snap" like the cable.

    The rear suspension on the Beetle is much like the front suspension on the FunBuggy.
    [​IMG]
    Only difference is that the Beetle uses only 1 lower link, and I'm using it to "push" the vehicle instead of "pull". Once again... it's safe to say that several components of this vehicle are highly experimental. /forums/images/graemlins/crazy.gif But I've learned that you can sit around arguing all day about whether it'll work or not.... but you really don't know till you try it! /forums/images/graemlins/screwy.gif

    Alan,

    I love it!/forums/images/graemlins/waytogo.gif

    Because my links (& springs) are not parallel, it tends to bind some in articulated travel. But in straight up'n'down travel - it soaks up the bumps like a pro! You might say it behaves a lot like an Early Bronco radius arm suspension.

    BTW, I don't mind the restriction in twist travel, cuz it actually adds "roll" stability w/out running a swaybar. And 'sides, the rear has plenty of "twist"....

    Hey thanks for asking....!

    I'll use the excuse that I've had some major personal issues this spring that de-railed my progress.... I haven't worked on this thing at all since January. :(

    That being said.... Last weekend I got back on it... and I hope that I've only got a month or 2 of good work to go on it.

    I'll make sure and post some progress pics...:waytogo:
