Rebuilt the steering, it works great and has a pretty long range of motion. I'd like to find some grease zerks that fit into the holes on the weldable hubs I used to build my spindles.

Front end is done, unless it breaks.
I'll need to read up on Akerman before I can try it.

A bit of progress. I have a neat idea that I am going to try out for that steering issue you mentioned Landuse, I will elaborate once I have it in place. I am liking the way it looks so far.
If I can find a place that sells TIG wire on Saturday, I may have this thing running this weekend.
:auto:

with the super long wheel-base he has, the extra steering angle will come in handy. if the kart was considerably shorter, the sharp steering angle could be a hazard, but i don't think it'll be an issue.

ackermann is simple. you want your steering arms to point towards the center of your rear axle. that makes the inside tire of a turn follow a smaller circle than the outside tire, so that niether tire "drags" when turning, making steering much more efficient.

Yea, I know how it works with the arms facing rearward, but not facing forward, and connected like they are. In the spring I plan to cut that front axle and make dual independent leading arms, and at that point I will do Ackerman. Thanks for the pic, that will save me some time when I get around to redoing it again.

Is this stupid comet clutch supposed to be some sort of free floating unit? I have beat the everlovin snot out of this ****able thing and I can't get it to tighten down snug. If I leave it as-is, the sprocket on the driven is allowed to move about 1/2".

Suspension is essentially done, although these shocks I took off an old motorcycle are really weak, and when I plop my fat arse down in the seat it pretty much bottoms out. I think I'll take the shocks off my kids kart and swap them. They might give him a nice smooth ride since he weighs about 160 pounds less than me.

Only need to hook up pedals, and I can go break it! Moved the suspension mount back a bit so it didn't have as much leverage on the dinky little shocks.

the way you've got it set up now is too long and fragile. hack off the narrow section, and put your pivots farther apart on the wider section. then spread your shocks out and move your shock mounts back towards the rear axle as far as you can. that'll firm up the shocks, give you a stronger kart, and a better turning radius! :)

Nice photoshop, but that won't work. You have a shock sitting right in the middle of my jackshaft for the CVT. If it doesn't work well enough I'll just cut it apart and redo it. The main point of building these karts is to give me something to practice welding on other than 6 inch strips of metal.

so move the shock over a bit so you don't hit the jackshaft. :)

you want the shocks out a bit for more even weight and stress distribution.

Got a road test today, everything works pretty well so far except for one itty bitty minor issue. My Dad had 2 torque converters, and gave me one. Except that he actually gave me 2 halves of 2 different ones, and they don't match. So I have a symmetrical driven and an Asymmetrical driver. I should have noticed it much sooner. >.< I guess I have to live with the old crappy centrifugal clutch till I can buy a new setup. Maybe Friday I'll have everything redone and get a bit longer test drive.

Got things all put together with the cent clutch. It does pretty well except for a small amount of negative castor that I need to get rid of. I think once I get that ironed out it will be a pretty fun little rig. Might try for a video this week if the weather doesn't turn.

Got the suspension redone, it looks terrible, but it works pretty good. Got rid of the negative castor and put it at around 5 degrees positive castor. I'll try to get a video done tomorrow.
