I built Jerry Howell's "Miser." His plans are good, and his "kit" of specialty parts is a convenient way to get the graphite for the piston and other things that might be a bit difficult to find.

When I first built it, if I held my mouth right and the moon was full, it would run on the heat from the palm of my hand. *THAT* was a highly satisfying experience. Since it's been sitting around a lot (years), it now needs a bit more heat to run than my hand can supply.
