Emily, the patent is not boring at all -- very cool, and the picture even better. I went to look it up before scrolling all the way through this thread and couldn't get the patent database to display any figures (missing a plug-in on my end, I think). I was picturing equipment not that big, even though I had figured out it was for mining. Do you do welding?
My three things:
1) I've lived in Michigan, Ohio, Tennessee, and (now) California
2) I can ride a unicycle, though haven't in more than 30 years (so maybe I can't anymore!)
3) I am married with two sons (9 and 6) and we have 15 chickens, two turkey chicks, 12 eggs hatching, and 1 occasional peacock.
