[Kartbuilding] go kart setup Course

Hi Wilkin,

I'm glad you liked the additional pages of the book I emailed on.

ERW tubing is "Electric Resistance Welded" tubing. It has an internal
seam. See the first image on: http://www.mechwerks.com/Frame_Tubing.htm
That webpage has some additional information. I think racing kart
chassis use seamless tubing with a thinner wall. This does cost much
more however.

On my karts I use ERW tubing because it is cheaper and easily available.

As for an A or X type chassis, you would just have to test making one
type of each yourself! I know that with a solid rear axle and no
suspension, the chassis has to twist when going around corners. Perhaps
this is why the X type chassis handles better. I never explored making
different types of racing kart chassis. I just settled on a basic design.
If you find out more information or make any discoveries I'd be
interested in hearing them.

Best of luck,
-steve

Hi Steve,

Thank you for your reading material, I received them all! and I have had
a great time reading it words by words during the weekend. apart from
the mechanic side, The book basicially covers everything about chassis,
seats, bumpers, was great!

but now I have lots of questions raising up in my head. what I dont get
is that in the chassis section, its says some use seamless steel tubing,
and some use ERW tubing, so what do most of the kart nowdays use? is it
the expensive models use seamless steel and the cheaper models of the
same factory use ERW tubing? I have asked one dealer before, he told me
that nowdays, most of karts used 32mm tubing, while some used 28mm or
30mm, so thats why they were cheaper... and 32 mm would give more
stability so it performs better..  dont know whether its true or not. lol.

then I remember I readed one Japanese magazine 2 years ago, It said that
apart from A shape, there was another thing call X shape like in my
attached photo (wildkart fighter model). It says X shape chassis can
perform faster in fast corners while A shape chassis is for slower
corners. is it true? but I found most of the kart factories today are
with A shape and only few with X shape..  if X shape are really faster
on fast conrers, why most factories are still sticking with A-shape,
there surely must have a lot of tracks in the world with fast and long
corners, so X shape should have gained some popularity.....) and some
factories like Maranello Kart came with a complete different looking
shape too, dont know what is it called.. May be its just rectanglar
shape being said in the book..

I received one kart magazine from my Australia mate 2 months ago, and
the tony kart advertisement says their welding, material control
technique is better than the other factories.. thats why they are always
winning.... I dont know, but most people must have believed in it. thats
why their karts are sold everywhere and they are always winning in the
front. lol.

Steve, Thanks for your printed page, it has inspired me with a lot of
thinking!.

Thanks,

Wilkin

    Hi Wilkin,

    Yes, the book "The NatSKA guide to karts and karting" does seem to
    be out of print.

    I emailed you a link to some of the pages I had scanned in.

    Please find attached some more pages of this book.

    Let me know if you get this ok.
