One tip, though. You may want to reverse all your track pins, to wit, remove them one by one and install them from the outside of the track, not the inside. On the inside, as some of the pins will slowly work their way out. one will eventually catch on something and rip the track link. Installing them from the outside seems to eleviate that problem. Also, it's easier to see one that is beginning to work out, and just shove him back in again.
Oh, man....it took me a half hour of cursing and swearing to get one pin out of one of my tracks- had to shorten it by a few links. I've got metal tracks, and the pins are rock solid. But I will think about it- better safe than sorry!
