Rear Tire Installation Failure

[Grumpy Goat]

GG, I now understand why you had so much trouble using your new Cycle Hill machine. As you know, I use the same rig and have always had good results with it.
...
For this install today, I'm at my new condo. At the old place I had the cycle hill bolted to the floor. Solid as a rock. Here, I did as per GG with a 2x10 under the car tire and the cycle hill bolted to that. Very unstable, and I'm not gonna use that method again.

While being bolted to the floor is the best mode, in my case due to lack of space I have to use the plank under the 1/2 ton truck front tire. I guarantee it does not shift.

Back when I was in better shape I could have fought this thing, but I suspect that my age is catching up with me (on top of the out of shape bit, and the hypertension does not help).

Glad you got it done though.
