Hi Fabrice...looking good!   I came across one of your posts on the US site regarding your use of plastic/nylon bushes to produce a free wheel.
Can you provide some more info on this method?  I currently have two wheels driven but am considering only one driven wheel.

Hi Alice,

Yes, the 2 driving wheels is not the best configuration ! I used this solution to my first CK but I had a lot of trouble when cornering....
At first, I simply deleted a key on a wheel
This simple solution gave me a good result, the steering was nice but less symmetrical
With two-wheel drive turns are difficult but the behavior is neutral, with a single drive wheel, turns are nice but the car becomes less neutral
Moreover, in turns "against" the free wheel there is more motor, hence my idea of isque "limited slip"
Be careful, this disc is not nylon but polyacetal or PEHD 500
I tighten the ring until I can not turn the wheel by hand
Thus, the wheel is still a little drive and a little braked and the car found a little neutrality, this concept is not "miraculous" but it works better than a wheel too free which gives asymmetrical effects in control....
I hope my Googlish is understandable enough to explain my idea ....

Thanks Fabrice, I like the idea. I’ve made several changes to my kart ( to lower the C of G ) so am going to see what effect these changes have on the performance before altering the drive. Probably a winter job!  It will mean moving the bearing to the inside of the chassis to make room for friction discs etc.Thanks, Dave.

Looking good.   Nice looking workshop too!

Is the figurine 3D printed?

Thank you for the comments
For the mascot, yes it is a 3D printing, and I have to do a metal painting....

Hello all,

My method for tracing body panels, I use polycarbonate from 0.8 to 1.00mm also called "Multiglass"
More expensive than paper or cardboard, but much more precise.
Some pictures maybe more comprehensive than my bad English ....

That’s an helpful idea Fabrice.   How do you transfer the pattern from the plastic sheet to the paper?

Hi Stefan,

I do not transfer plastic to paper, but plastic to Alu sheet directly
In fact the plastic panel is almost the exact size of the sheet metal panel
For the exterior layout, I go around the panel with the pencil, and for the rivet lines, I extend my lines on the Alu, a bit like a pattern in the seam .....
I could even if I need, drill the holes for the rivets, if some places had to be specific ...
To make it simpler, the plastic panel is a true copy of the Alu panel (same size, same thickness)

Photos 5 and 6 show the Alu panel, not paper

Soon

Ah! I thought it was paper and didn't understand the need for that step.  Thanks S

That looks excellent and a much better finish than mine. I have gone for the good from afar but far from good look.  ;D
If you can drive round corners, you're not going fast enough.
