Go to Post FIRST is an amazing combination of principles that, when applied to the world, has had a monstrous effect on the way High School students learn, think, and relate to others. - Amanda M [more]

Re: Box tubing inconsistenies for WCDs

Quite honestly, until you're chasing after the last few available percentage points of efficiency in your drive system, tolerances down to the 3rd decimal place digits are ridiculous to make a fuss about. Precision to the hundredths of an inch or order of 0.005" at best would a more realistic goal for most teams when aiming to line up their snap ring grooves and drive components. It's better to have things exact, but at the same time it is not entirely critical to the drive system working.

While tolerances do stack up, adding on a 0.003" MAXIMUM variation (based on what I have seen and heard from others) is not going to have a profound influence when you aim to line up components over the length of your robot to within 0.020". If that 0.003" is the last straw, then you have another 0.017" somewhere in your system that you likely have more control over and would be more easily addressed. Go for the lowest hanging fruit first, then work toward a more elegant and optimized solution later as you chase excellence.
