Nice write-up and pics, doug. I might add a couple of things: If you don't have a 3/4 ton pickup, a 2x4, and old railroad parts about, then look into this gizmo: http://www.tyrepliers.com.au/
Works great, although there are only a couple of places in the US that sell them. If you are a tinkerer and have a welding machine, it would not be that tough to make. As a lubricant I use ru-glyde, which you can find at Napa. Works better than anything else I've tried on rubber. Too bad it doesn't come in anything smaller than 1 gal.
If you're in So. Cal, I've gotten the curvy irons at Chaparral in San Bernardino.
