New member! New OFF ROAD PROJECT!

[Raywelder]

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.

Open differential rear end, when off the ground, they spin opposite.
Limited slip is posi.

Frame looks good, looks similiar to my layout, except I abandoned the rear swing arm for Independent suspension like the front.

I think I would have mounted the shocks inside the A-rms, instead of on the top one, Of course, it works the same either way, but I like the looks of it done the other way.

 

[03BLACKGT]

Yeah I had planned it out so that the shock mounted on the lower a-arm until i brought the steering rack in. I was way to tight so i had to move it up top.

I had a few set backs today. The sprocket I was using didnt fit on the rear diff so I had to go out and buy a new 60th 41 chain. After I got that on, the length of the jackshaft set the motor to far over that it rubbed on the rear tire. So I had to buy a smaller shaft with a keyway all the way through and relocate everything. Should have the new motor mount welded on by tommorow.

So is non limited slip and open dif the same thing?

Yea, Except its usually not called, "non limited slip" Its either open, limited slip, or Locked.

Open being one wheel drive basically.

limited slip being, both wheels lock together under torque,

and completely locked is just when the wheels are locked together all the time like in a welded differential.

I can't wait to see if together and running!.
You said you were going to put a cage on this right?

 

[03BLACKGT]

Lol a cage of course. I almost flipped the junker i bought for parts only having it for 1 day. It didnt have a cage

 

[Raywelder]

You building the cage from pipe or squaring tubing?

 

[03BLACKGT]

The plan was to have a square frame and a round tubed cage, but im not sure yet. I dont have a bender availbe for such a big diameter round tube. So it might just be a cut and weld square cage. Idk yet. Still contemplating

 

[Raywelder]

I dont have a bender, and still built my go cart and a minibike with tubing, to bend mine, I just take a grinder blade, cut 5 or 6 little slits or pie slices out of the pipe, and bend it up, then weld it back up. Time consuming, but it works. And you usually get fairly tight bends if you need to.

Heres the suspension I built for mine on the front,

Sadly, I think I'm going to cut it out and take the suspension from an IFS truck, lengthen the A-arms, and Run small trailer wheels up front.
I'm doing the same thing on the back, except using the Front end off on a 4wd truck with cv joints.

If you go with round tubing you could do what I did... maybe. I borrowed an EMT/Conduit bender from a friend of mine who owns a electrical company. Or you could rent one from your local tool rental store. I found that most of the chain stores don't have them, check the mom and pop places or either a local electrical supply company.

 

[03BLACKGT]

Ill check the local stores first. Thanks noley. If not, then I like your idea Raywelder. I got a handy torch that could make that pretty easy I guess.

Anyway, I got the steering rack mounted by modifying the stock mounts. Also cut the the rod ends off and welded up some smaller ends with a tapped round bar. The ends seem really weak compared to the rest of it, but I think its more of overkill on the rack. Ive seen the same ends used on karts similar to mine so... here it is.

Now take the shocks off, leave the rack and tie rods attached to the spindles, point both tires straight ahead, and now lift the a arms up and see if there is a toe out change on the front wheels?

theo

 

[Raywelder]

The top of the tires should lean outward shouldnt they? I think mine do when I lay the frame out on the ground, but I can't remember.
I like your steering rack setup, Thats what I'm going to do when I get ahold of one.
How much did it run you?
I may be getting one for free, thats bent, off of my friends race car though.

Watch your weld where you welded that thead rod or carrage bolt to the rack rod. Doesnt look the safest.

Yea, looks like it could use another bead run around it.

 

[03BLACKGT]

ohh its not welded yet ... nothing is. lol. I welded the threaded rod to a small piece of 1/8" plate then tacked the plate to the rack. Its gonna be beveled and welded for a full pentration pass. then gonna build up the weld around the thread rod. Possilby even add small brackets for more support.

As far as the toe is conserned, Im expecting some, but no havent checked how much yet as how nothing is welded and dont want to put to much pressure on anything. Thanks

Harbor freight has a cheap 100 dollar bender. It would work well enough for this Im sure.

I've read a lot about that bender online and it is not the best for tubing. It is meant for pipe; pipe and tube are not the same.

Some people report success with tubing and others say it is a waste of time & money.

Yea, tube is structural, and pipe has like internal strength or something?

The HF bender will bend tubing real well if you pack them with sand. But that's a lot of hassle. I wouldn't hesitate to use black iron pipe for this though, Its plenty strong for a cage on this, the bender would work better for it too.

I've read similar reports on the bender, almost got one for half the price on craigslist, but decided to save up for a good one, as I plan on using it a lot more.

 

[03BLACKGT]

I actually own the HF pipe bender... works great on pipe. But black piped would make for a much heavier kart that it already is. Ive tried it on tubing, but not to satisfied. The sand trick is new to me. I do have a few bags of sand. Might give it a shot.

 

[Raywelder]

oh, You have a bender already! What the heck man, Get to work! haha.
Yea, you just take the tube and pack it TIGHT with sand, Then you do your bending.
Theres a youtube video on it, but They ground out the die to fit the tube better too. you may have to grind out the die a bit. I'd say screw it and do a black pipe one lol.

 

[Buick455]

I actually think the sand trick was started by the moonshiners to coil there copper for the condensers... Works pretty well, I have tried it.

Also if the HF bender is like the Northern bender you can get different dies for it. I'll look for the link I found and get back to you.
