Axle help please

[ohiofitter]

I do polish my bores,Sand burs and crimp marks, This year I tried different time on each nail ranging from 30 seconds 2 minutes,,,I start with wet 800 work to 1000,1500,2000 , then go to micro mesh up to 12000. After graphiteing the wheels The best time I can get on a spin is 20-25 seconds. What am I doing wrong??

The "spin-test" really isn't a good barometer of actual on the track performance. There are many variables that determine how well a wheel will perform under race conditions.

Ohiofitter, in my opinion 2 minutes is way too long, even 30 seconds on one step/grit is too long. Even with the 12000, if you go to long at a high rpm, you will reduce the axle diameter. 15-20 seconds with each step should be plenty to accomplish what you need to. Finger spins don't necessarily translate to speed on the track.

With the finger spin, you are only testing one friction point, and that is with no weight applied to the bore/axle combination.

Once the weight of the car is put on the axles, other friction points and alignment will affect your speed also.

Good luck.

spin time is good to have but really as others say other factors come into play with the wheels and alignment process.

Personally as long as you can get a fast spin time over 20 seconds you will be fine. but just remember like others mention.

You can go to far with this and reduce the diameter of the axle, causing poor performance.

1500 grit, 2000 grit has been fine for us.

you still have to have a good graphite and great alignment !

Thanks for the help guys
