Sadly, it is all healed now. No battle scars.

But it is kind of a neat spirally looking burn.

I was turning some gate hinge pins yesterday and a chip flew up and got snagged in my safety glasses. Got burned on the cheek while shutting it down and getting my glasses off. Looked in the mirror this morning and had blood all over my face. Oh well, glasses worked and eyes are as good as any other...

I remember those days. We responded to a pickup truck fire in a large shop. Hey 30-40' ceiling height, piece of cake to extinguish. Then dispatch told us it was a propane conversion with a large tank in the bed.

Raises the pucker factor a tad...

Dave, I had not considered, till I read your post, the requirements of a propane system in an automotive application. People in the 70's used propane conversions for 460 CI engines, being as propane is 90,000 BTU per gallon as opposed to gasoline at around 120,000 per gallon, those required some rea...

36" of water column is 1.3 PSI (3 x .434). Yes that is quite a bit of pressure for a flammable gas at it final orifice point. In fact about 3 times what is customary on propane gas.

In my experience turning them is a waste of time, money and new pads. If the rotor warped when full thickness the problem will only get worse with less mass.

Circumference of 14", not diameter of wheel.

I assume you are driving the 14" "wheel" with the 2600 rpm motor. If so. then your wheel is covering 36,400 inches per minute. Seems it would travel a mile in 1.74 minutes.

You would have to slow the wheel considerably to travel 36,960' in one hour.
