It is touching the rotor now and then, but I was conscious not to use it as a fulcrum point. I'm certain that it was OK, but I might come up with a stop or guide of some sort on the vertical bar where the high end of the tool will ride, keeping the angle so that it can't even touch the rotor. Good point.
Yeah, yeah, yeah- to everyone, the rear is a bitz, I know- I've attempted it with tire irons before! Notice no video of that
with "attempt" being the operative word. It was one hell of a workout.
Sure, I'll be amazed if this tool will dismount (would save me a few $) or actually allow me to mount the rear. For one thing, before I even attempt it I'm going to have to anchor that stand better.
As I said, if I can continue to do half my tire changes more quickly (no driving/wait time), cheaply, and with less chance of damage, I'm going to call it a success.
