AND ANOTHER VIDEO IS UP!!!!

Chassis build part 2 is up on youtube. This is what you will be seeing at stretton from me this Sunday. I even included some different music for different tastes ;)

once again, share and ask away with any questions or improvements you have to both my cyclekart and editing skills.

the rail part of the chassis is done!

School has slowed me down lots but I'm currently editing the last chassis video and I think the next thing to do is suspension. I'm intrigued to see what you all have to say about my suspension because I'm trying something I haven't seen on a cyclekart yet...  front sliders. Springs have been ordered and I'm waiting for them to arrive.

cheers, Marek

Do you mean sliding pillar like a Morgan? Though I've now got 30mm diameter springs fitted, rather than the 40mm ones shown. I'd avoid building in camber as the camber increases as the kart leans, I'm going to have to modify mine to take the camber out.

by sliding I mean the leaf spring is fixed at the back but at the front there is no eye, it slides through a shackle. its not very common but was used on some pre-war cars including one of the 4 origonal delage 15-S-8s. its something different but I thought I would give it a go

Known as a "sliding trunnion". Common on many sporting type cars at the rear. Normally the trunnion that it slides through is able to rotate in it's housing to a limited extent. Often bronze.

Wouldn’t that need a pair of parallel radius arms?

They're also known as "slipper springs" and the flat end to the leaf is supported in a trunnion.  The Bugatti Type 35 family have them as the rear mount of the front leaf.  I think the Napier Railton may even have them at the front.  They are still used today on some vehicles with leaf springs.

One end of the leaf still has an eye which locates the front axle front to back so there's no special need for a radius arm - at least on any of the period cars I've looked at.

P.S. I thought my suspension choice might bring up some discussion. I will explain more when the springs arrive.

hi all,

My springs have arrived.
I can start on the front suspension soon now, the springs are looking good and I'm intrigued to see what you guys think :) :)

They look quite flat, is your axle going under or over?

Great videos by the way Marek, keep up the good work!

Thanks Chris,

The axle is going on top and the flatness and this is to lower the ride height from the original plan of 16cm down tabour 7cm if I remember correctly

Love it. Can't wait for more videos. Your saw shows the value of carefully drawing things before diving-in freehand. I am definitely getting one, they make a great job
