Dear Nigel & Simon,
Not sure if there's another email whose text hasn't made it through here?
Your comments re-the Wheal Henry engine house make it sound very like the Herodsfoot one. I had thought that the engine might have been a rotary type, driving both a winder and a pump via a crank and connecting rod to an L-bob via the doorway in the wall adjoining the shaft.
Did the one at Wheal Henry have its engine fully inside the house?

> Hi Simon,
> The Watt engine house often had a doorway through the side walls (both sides) just behind the beam wall. This sounds similar. Would suggest a visit to the Wheal Henry engine house near St. Day in the Poldice Valley. A very unusual house which is said to have operated a shaft in the valley bottom. House is c.1790 to 1800 date.
