Alex will get an A+ now! 'Cause I'm going to have him add the section on methane!! THANKS!!
Seriously -- the thread was really intended for a guy to read that article and "somewhat" get a handle on all this various info - like bore sizes and what that means etc.
I didn't want to start a "boring" (pun) thread on high tech math and all the various nuances of a bullet proof track style brake system... So I get a bit annoyed when people start with the "well if you jack B into A and deduct the length of a piece of rope...." and the thread goes all over the place...
It was more a "hey" -- if you're interested -- here's a pretty decent article that breaks (pun intended) it all down.... and you can go from there. No biggie.
