And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

I dunno what's going on here, but it looks dangerous and fun
its one of those cases where you have to do all the drivers at the same time so all the drivers have the same contact pressure with the track. makes one wonder what the coefficient of friction is with steel track and iron tires with 100,000lbs pressing down.
Probably replacing the steel "tire" on the driving wheel.
ReplyDeleteHeat 'em up and slip it on.

DeleteYup. That photo looks pretty recent, I'm curious to know where it was taken. A bit more detail on the process at about the 16:00 mark in this video---
