This happened to me last summer.

Packing up to go racing. Haven't looked at the cars since last time. Been busy with other stuff. Axle is way too sloppy. No time to change bushings.

Looked in my capscrew assortment, found one that measured .0965". I think it was a 2.5mm or 2.6mm. I augered that through the bushings. Nothing to loose at this point. Well, it worked. Took all the slop out. Lasted several races. Not my finest craftsmanship. A hack.

if you have anything like that, post it up.

Not enough room in this thread to post all of my interesting finds.

Ask Guy he will vouch for my "creative ideas."

Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free. - Ronald Regan #40 (1911 - 2004)

Yea. David has found so many ways to cut a tenth of a second off his lap times, he now laps track in another dimension

Mark,

In real engines, that 'technique' is called knurling, as you may know. Not considered best practice, but maybe decent 'shadetree' work, and if done well, it does work... for a while.

Never forget that first place goes to the racer with the MOST laps, not the racer with the FASTEST lap

I hear you, Cheater. I have a valve guide knurling set. Probably what made me think of this hack!

 

You get a better job with bronze wall guides, or replace the guides.
