<DIV><FONT face=Verdana size=2>Hey Kart builders ?
I dont actually know how this list thing works or who reads this but if it
is anybody who is interested in kart building then you might find my
kingpin arrangement as per the attached pics, of some
interest.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>As you can see the stub axle is fixed to the
threaded-rod kingpin by way of the nut and grub screw - note the flat spot on
the rod. </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>So the kingpin itself pivots through the nuts top
and bottom. The thread arrangement takes both vertical and lateral weight and
the streering is as light and smooth as.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Ok so as the pin pivots its 45 or so
degrees the axels have to lift or lower half a mm or so but hey, the kids
have'nt bitched yet and with 8 degrees castor and kingpin inclination it would
be hard to pick.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Also - the rubber bush, whilst a bit clunky, does
a great job of allowing pivot and flex without any slop.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Note the trailer, formerly a golf buggy,
currently fitted with a seat for our 1 yo. </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Also the pair of feet pegs currently laying down
that can pivot up and lock in sideways for shorter legs. </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>What's missing in the pic is the engine who is
currently writing this. Amazing how effective a broom can be at
transferring power.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>This little outfit is a couple of years old
now and has had a great workout by heaps of kids.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>And a note to the moderator - I exchanged a
couple of e-mails re: principles of steering geometry with a very knowledgable
guy called ( I think ) Steve I found on the web, before I set out to build the
kart. I promised to send him some pics when I was finished but the computer
crashed, lost the e-mails etc. I've trawled through the web recently trying to
find him and I was thinking perhaps it might be you. If so - cool - you
might remember me from the threaded rod idea. If not pls let me know and I'll
keep looking.</FONT></DIV>
