Re: AndyMark 8 Inch pneumatic hub fail

Chuck, thanks for the kind offer!

All, here is situation.

The pressure in the outside wheels was at 15 PSI with the center wheels being at 25 PSI.

We went to add pressure today when we noticed that the frame had a bit of wood from our defenses. Indicating that our tires were compressing enough to allow the wood to contact our frame. Our frame is designed so that the defense can not directly touch the wheel hubs even without a tire on the hub. We have at least a 0.5 inches of aluminum between the hub and any outside contact.

We used the hardware from AndyMark on the Hubs without any locktite.

We drove the heck out of these, thinking we would rather brake it in house that at a competition.

It broke, just not where we thought we were vulnerable.
