Anyone try a guide pin for Dominate Front Wheel?

Pinewood speed is about reducing friction so I was thinking, instead of the DFW rubbing up against the center divider of the track, why not install a small metal pin between the wheel and the divider.

This way, the pin would slide along the rail and would create much less friction than a plastic wheel that is creating forward and rotational friction.

Might be worth a test for those who own a track.

Interesting thought! My first thought was that the guide pin is so much samller that it might be possible for the pin to find any minor imperfections in the track like at the seams or something??? Also with it being metal on metal, would that not create more heat/friction???

You're welcome to try it but the wheel against the rail is much faster because it is rolling and not stationary.

true, but you have greater contact-to-rail with the wheel with both forward and rotational friction.

wish i had a track to know for sure

the wheel would find those imperfections as well.

i am envisioning a NEEDLE angled backward about 20 degrees.
 
It can easily be tried by anyone that has a track and a three wheeled car. Steer the car the opposite way, against the guide pin and see if it's faster. Anyone willing to try it? It'll take 10 minutes. /images/boards/smilies/thumb.gif
 
I would assume that it has already be tested, but the only way I can see it possible working would be on a Street Pro car...with the use of a delrin washer on the guide pin and steering the car ever so slightly the other direction so that the washer rolls along the rail??? But with that I still cant imagine that not being tried and found to be slower
 
Should we change our terminology and refer to the cars as "Rail Sliders" now? /images/boards/smilies/wink.gif

Your DFW is sliding because it is trying to turn, but going straight down the center rail... spinning and sliding...

I'd call this "wheel scrubbing", remember you heard it hear first. LOL You'll have to mentally orientate this image in your head and I believe you'll find that we are running a negative scrub radius on the DFW.
