Adopting NSC rules for wheels - Inspection Advice?
Posted: Mon Aug 17, 2015 7:59 am
Hello Derbians,
So after some discussion with the organizers at our District, I was able to make a successful case for adopting the Northern Star Council's rules on wheels and axles. Specifically, this means that the axles need to be metal, with a nail-type head (we can't inspect for anything more than that), and for the wheels (paraphrased):
- All lettering, numbering, spokes and fluting is present and visible.
- Wheel diameter is 1.16" mininum.
- Tread width is 7.5mm minimum, and flat and parallel to bore.
- No material removal from inside of tread.
Can anybody suggest a good process to follow to train inspectors to check wheels? I want to be able to give them good guidelines to follow, so that we do it in a consistent and efficient format. If anybody's been involved with tech-in at a NSC event, I'd like to hear from you even more.
It seems like you could do something like the following:
- Check for lettering/markings/etc.
- Use small flashlight to check inside of wheel for material removal.
- Slide go/no-go guage over wheel diameter to check for minimum diameter
- Slide a different go/no-go guage over wheel width to check for minimum width
Does this sound like a reasonable way to go? I'm a little worried about fenders making it harder to check the diameter of wheels, so I'm eager to hear how that's been dealt with in the past. Also, thoughts on 'aero shields' would be welcome as well.
