Poor Little Cone Style

RRR, please keep posting. Whether you correctly explain how something works or not, the resulting discussions are very informative. I am a mechanical engineer, but I've learned years ago that I know almost nothing of how many things actually work - but I don't care! I think a line in Joe Dirt was "Who knows how a Sure Grip [posi-trac] actually works, but it doesn't matter as long as it works!" sums it up best.

Best wishes to everyone who tries to help others!!!
