My frame design

[Aselim]

Hey guys
I finished up the frame design and I think by the next week I'll start building , plz check them and tell me what you think
waiting for you replies
Measurement of the design are in CM for length and Degree for angles

I'm sure your thought about it but, are you going live axel? If you are just check you rear width to install hubs and bearing blocks/weldments

Looks good!

 

[stephenm2682]

nice, looks like a paper airoplane

 

[jeepman09]

LOOKS GOOD! are you going to use round or square tubeing ?

 

[dragracing1213]

Are you going off road or are you going more for speed...
Looks like a good project so far though...

 

[stephenm2682]

any progress on this yet?

 

[Aselim]

hey guys
sry for the late reply , you know I'm at Egypt .. Just kidding
I'm going of course to square tubing and live axle
I bought the tubes today , I got the 1" and 2mm thickness .
the progress is a little bit slowly because i work only on weekends , but i think by the end of the month it should hit the road ..

on this plan, the lengths 92.50 & then 55.00,(back to front) will this be a continous length of steel or seperate sections and then joined but surely wouldn't be as strong? wouldn't it also be easier to use roundtubing then you could bend the angles? any views on this anyone?

The less you need to weld the better, but you really cant get fancy without cutting. Tryin to keep your angles as notched bends (pic 2) would be stronger but its really up too the person building it. good welds are good welds.

I would try and do it this way though with the notched bends:

 

[stephenm2682]

sorry for being thick but whats the top part of pic2?
i take it a notch means cutting into the straight section to then slot & weld the other piece in to it?

 

[Buick455]

Ok, you have a square tube. You want a 45 degree bend. look at the pictures below... lol

 

[stephenm2682]

lol yeah i know that much, i was talking about where the green frame joins the red frame on your pic? on the angled part, where it joins the middle crossmember

I think I'm missing the question here...

The red section would be all one tube miter cut & bent (about 14' long to start). The cross-member would be another tube cut to width and welded in squared. The green would be just like the red, but at the ends it need be sliced (151 or 29 degrees depending on how you look at it) and then welded to the frame...

Hello guys
I just wanted to say that you changed my whole point of view
we already bought the tubes and cut them in a very very stupid way "of course after i saw your replies "
I think I'm gonna get rid of the tube i bought and get new ones
cos we don't have any idea about the welding techniques we did a very stupid job
thanks for your work and I'll take it into concideration

Ok, ur going to need a tun of support on that frame. Make everything triangles so put a few tubes across the rectangle and square parts of the frame and make sure u reinforce those front wheel mounts or they will snap off. I used 1" tubing on mine which is about 3mm thick. Its strong enough if u, like i said, reinforce everything. Should be a good go kart once ur done. Good luck!

 

[stephenm2682]

so does everyone recommend about 3mm thickness? i was too thinking about using 2 or 2.5mm?

I would go with 3mm, its just a lil bit stronger.

Weldong is done

Hey guys ,
the welding is finally done and those are some of the pictures.
I'll post some more when I get them from my friends camera
so what do you think ??

 

[stephenm2682]

that a stick welder? why you not wearing shield?
