    Designing a very simple gravity powered cart

    Dam, I already ordered and received the HF wheels. Oh well... Does anyone know where to buy high speed bearings? and I made a little progress this weekend. The steering is completely functional. I just have to mount the axles and wheels, and make the brakes... And I still need to find a seat...

    What can I possibly do with a 89 accord?

    200k on a honda? That thing's just broken in!

    Designing a very simple gravity powered cart

    I do have washers... and they are wobbly. Maybe I should try and cut out some plastic! Excelent idea! And as for progress, I haven't done anything yet... lots of homework

    Designing a very simple gravity powered cart

    Thanks for the tips How would I keep the wheel on the axle? And where could I find high speed bearings? EDIT: Here's some pictures! I've been really slowly working on it every day. There's still a decent amount of things to do... Front Iso: Note the blocks on the foot rests. These are...

    Designing a very simple gravity powered cart

    Replied via pm And, I've been working on the cart. It's coming along quicky. I still need to find a seat and a steering wheel, and I'm waiting on the wheels to be delivered. Other than that, only a small things remain which I'll take care of tomorrow... the pulley system, and the tall...

    Good deal?

    What would you reccomend for a motor size?

    Good deal?

    So if I did get this, and eventually replace the engine, what would I look for? It'd probably be either me (150 lbs) or me and a friend (at most, 330 lbs) Should I look for a 125cc bike engine, or bigger? Oh and I plan on running this in atv trails, they get really rough and have plenty of...

    Good deal?

    http://newlondon.craigslist.org/mcy/1458901396.html I've been doing some research about building some sort of buggy for atv trails, and I've found it'll definitely cost me at least $1000 to do everything right, especially because I'd have to buy almost every tool needed for the project. So is...

    Designing a very simple gravity powered cart

    Well I'll make sure to find a bigger hole saw! and here's a better diagram of how I'll wind it around. You can see it's only wound around more so the steering shaft has plenty of friction:

    Designing a very simple gravity powered cart

    Well my idea to adjust the steering is to change the size of the shaft by using a hole saw and making a ring that goes around the shaft. I'll probably want shaft with a diameter of 2-2.5" because that should pull the rope about 19-24" with 3 rotations which should be about right. (I used math...

    Designing a very simple gravity powered cart

    Following your advice, l redesigned! I redesigned it to use steering wheel steering. This allowed me to put my feet in front of the front axle, giving proper 50% weight distribution. I designed this to have nearly perfect distribution, maybe biasing the rear by <5%. Also, this shortened the...

    Designing a very simple gravity powered cart

    Update! I went to home depot, got all the things l need except for screws since I still need to take a look at the plans and see how much and of what lengths l'll need. I got 2x4's but they're out in the garage. I have 8 big nuts so I can lock them together, and there were no 5/8 nylon locking...

    Designing a very simple gravity powered cart

    Ok well I'll quickly redesign this (for porsche's ideas), I appreciate all the help! Here it is! I can post a nice 3 view drawing with full dimensions later, but now its 55" long, and the back of the seat is 40" from the front, making the center of gravity about 32" from the front, which is...

    Designing a very simple gravity powered cart

    Where did you find the wheels for $6 a piece?? I know they're on HF for 10, and the groove thread version (which I suggested as an idea) is 8 or 9... Ok i've redesigned this accord to the new ideas. Note the new brakes... actually thats the only change I made. I have two brakes in case I need...

    PROJECT: (S)crap Kart

    For the pictures, I would try using a self timer and a tripod. If you don't have a tripod, tie the camera to something stationary and use the self timer. Also, if you have a point and shoot camera (like me) or a vast knowledge in photography (not me), try a longer exposure which is in your...

    Designing a very simple gravity powered cart

    I like this idea! So would I attach the rod with u bolts? and for the wheels, I'll just go to home depot and buy some sort of cheap rubber wheels, see how they hold up, and then maybe buy nice go kart wheels for my later gravity racer!

    Designing a very simple gravity powered cart

    How will navigating the curvy roads with single pivot steering be? And it just feels silly to spend over 30 dollars on tires for a little project like this

    Designing a very simple gravity powered cart

    Well, after realizing how quickly this project has become complicated and expensive, I've decided that, at least for the first one, I'm gonna keep it really cheap and simple. This is what I'm going for, only, without those brakes... I'll try and find a way to make them out of wood. Where...

    Designing a very simple gravity powered cart

    Thanks for the input! How hard is it to learn to weld? I'm really considering buying a MIG welder off craigslist and welding a nicer chassis together. How difficult would it be to learn to weld, and then weld a fairly quality frame? Also, what other tools would be necessary, and what kind of...
