New member! New OFF ROAD PROJECT!

[03BLACKGT]

Whats up guys. Name is Alex and I just want to start by thanking everyone here who has contributed in some way to this site. Before i started my build, I took lots of info and ideas from all over the web. This forum is by far one of the best. Now to my kart.

This is my off road rig that Im about 2 weeks into.
Its a 10hp techumseh motor with a comet 40 series tc. (I had an 8hp motor with this clutch on an old kart and that baby did about 40-45.)

Frame is BIG, but its intent is on a 2 seater. 1.5" sqaure tubing 1/8th" thickwall will make up the lower frame and probly 1" round tube for the cage later on.

Twin a-arm suspension up front with 2 mechanical shocks and there will be 2 shocks in the hinged rear as well.

I pulled the steering rack and pin out of a 92 toyota corola. It will need a trim and to weld some smaller rod ends on. About 3/4 revolution of the steering wheel turns the tires from a full left to a full right.

Tires in rear are 22/11/8 i belive and front are 16/?/8.


WHAT DO YOU THINK!?? I can use all the input I can get.

 

[03BLACKGT]

sry ... pics were to big at first

Are you going to shorten the rack?

theo

 

[03BLACKGT]

ya the rack will get shortened and the rod ends will be replacex with much smaller ones

 

[modelengineer]

Looks great. Are you going to add more support to the front suspension 'box'? It looks like it wouldn't take much atm to fold itself upwards.

 

[03BLACKGT]

yeah its gonna tie into the cage and sterring wheel supports. gonna try to run a brace from the front and rear of the front suspension box. not sure exactly how yet. Lots of triangles

 

[BradenM]

Damm,thats mighty fine. Great work!

 

[Jerryburger]

Really cool. Of course videos will follow....? HINT!

 

[03BLACKGT]

of course videos! whenever i actually get it running. Its only been a a couple weeks, but it feels like Ive been working on this forever.

Anyways I started making shock mounts up front but not sure if my current idea is gonna work.

In the blue circle ive made 4 holes for almost 2 inches in height adjustment. The red will be 1/4" triangle plate for a little more support. Any thought?

 

[dpaxson]

i'm not an expert but you're kingpin brackets look a little weak compared to the rest of the frame. If it were me i would put a couple triangular gusetts or something on the top and bottom of the brakets. Your kart is looking awesome though!

 

[theo]

you don't need any gussets, there is no for and aff load there, just side. What wall thickness are you using with that square tubing?

theo

Dude,

Your buggy looks alsome.

Your frame is going to be PLENTY strong.

Why did you go with two different sizes of wheels?

Also, where did you source your hubs and axels?

[mccolld]

Oh, one last question.

I've been thinking about going to Pull-A-Part and getting a rack like yours. What did you pay for it? If it's close the the cost of a new buggy rack, I may go that route.

Doug

 

[03BLACKGT]

thanks for the input. the 1 1/2" square tubing is .120 wall 1/8" more or less. i got the steering rack for 48$ w/out tie rods but im not usin them anyway. the front tires are temporary marups. -alex

 

[theo]

Man that's thick tubing you are using.

theo

 

[03BLACKGT]

its my first kart and i want it to last lol. im gonna run it hard. it might see some big jumps in its time

 

[03BLACKGT]

Doug i got the rear axel with the diff from northern tool (100$) and its worth every penny. i can do donuuts and drifts but with stength of a solid axle

 

[modelengineer]

Is it a LSD? Or does it to 1 wheel burnouts and drifts?

btw the buggy looks awesome. Have you seen mine? http://www.diygokarts.com/vb/showthread.php?t=2503

 

[03BLACKGT]

Non limited slip ... (correct me if im wrong). Tires spin in opposite dirrection when you spin one with no load. I had been watchin your sidewinder build Andrew. Looks awesome! Thats my favorite one so far. Im just not a "plans" kinda guy lol or I would have stuck to that layout.

Anyways... progress for today! Got the whole front end suspension tacked up. No more jack under frame up front.

First pick is at the 2nd highest position and second picture is at the highest.

 

[for the kid in me]

looking good
