I’m sure those old stools are a holdover from the early lookoutbdosborn wrote:Tom&Shelly wrote:As for the half inch or so of glass insulation between the legs of the wooden chair and the thinly covered metal floor, when the lightning bolt travels several thousand feet through ionized air, what's to prevent it from ionizing that last few inches of air around the glass?
Bingo!
I saw one of these when I was a kid visiting a lookout station, it wasn't till many years later that I understood why it wouldn't work. Air is a very good insulator and the lighting has already traveled miles through air to get to you; the glass insulators don't do a thing. The idea behind lighting protection is to have everything inside of the building rise and fall at the same potential as the lighting is conducted to ground around you.

He was a machinist for International Harvester. We ended up bringing home a 1969 Cub Cadet lawn tractor with a wagon and snow blade. He was the original owner in 1969. He clearly took exceptional care of the tractor and it was too cool of a story for us to pass up. In addition to the tractor we brought home a 1944 Delta Bandsaw, a 1955 Delta drill press, a 70’s era Atlas metal lathe, a bench grinder and cheap router table.

Hmm, good idea. I've already had one go bad...
