Neither am I. Deb and I have been readying the barn for a new baby pygmy
goat being shipped up today but other than nails and fencing there isn't
much metal content to the barn.

Tethered eh? Maybe you should've used an animal named power plant, say a
Falcon?

Breathing smoke sounds like a show maker to me. Perhaps a good first project
would be a forged dragon's head large enough to cover the exhaust port, then
a more volatile oil, a sparkplug and . . . Voila! Show time! <grin>

Tune time for sure. Tup Top Taps To Terrible To Tolerate!

Buick to dragon's head! Three nostrils to a side will make for a most
dramatic fire breathing power hammer!

it ain't real.
Wrought iron is.
