u are after mild steel EWS tube of what size? i dont really know

it depends on the size and type of kart u are building
do u have a picture of a kart u are going off or a plan

if i was building a ladder frame then id start with 40mm x 2mm
but i must stress iv never build any thiung that small so i wouldnt know

I'm 6 foot tall so it wont be tiny! It's going to be a full suspension kart but not from any plans - just what we have designed.

Could be similar to the basic frame of http://www.diygokarts.com/vb/showthread.php?t=14442&highlight=kind+road

Thanks

Anybody any clues? I was told an inch and a quarter would be good but what thickness!?

Probs 16 gauge tube. It depends how strong/heavy you want it.

The fact that your designing a full suspension kart without having any clue as to what material to use concerns me.

Tubing is stronger than channel, So your off to a good start there. Any decent size tubing will work, but it really depends on what size person is goona be riding it and how big of strain you will be putting on the frame via the engine. Large engine plus fluffy fella means thicker tubing required. When i build something i ALWAYS use rigid pipe made for electrical use in 1" size or MAYBE 3/4"..nothing smaller. but i am a fluffy fella so that being said i need to be well assured my fat butt won't go flying across the field when a weld breaks or I bend a tire spindle cause the frame broke! Fluffy and flying don't end well on most case's.

Learn some good welding skill's, cut the pipe's so that they give plenty of area to weld to, and last make as many good angle's as possible to strengthen the frame...remember, tri's are your friend here! They will allow you to brace and make a strong frame without adding ton's of un needed weight due to over bracing.

Thanks for this, I understand your concerns but it isn't just me doing it - actually my step father who used to manufacture motorbikes many moons ago is helping me.

I'm just trying to do the research and gain a full understanding so that when I go into this project it's safe and properly done!

Thats what this forum is for. If we were born knowing everything the world would be boring
