Axel Groving

[wisconsinraiderfan]

I read through the rest of the threads and haven't seen one on the topic of creating a grove in the axel to reduce friction with the wheel. What is everyone's thoughts on this?

Grooving the axle will not reduce the friction,but it may act as a reservoir for some graphite if you have to run many races.I am not sure if I really agree with having alot of loose graphite in my wheel bores either .Here are a few links to help explain a few things.

Ok so if that was true then the thin wheels would not be faster then a set of stock wheels sanded flat and lighted? and the link you have with the pice of wood, that is with out lube I have done test the same way but with graphite in it and the smaller pice is much easer to move. I think it is somthing to do with the graphite is taking up the #. I do not know this for a fact. I my self like to grove the inside of the wheel bore and leave the axle smooth. this works for me.
