Martin has taken detailed measurements of the engine and bob, as well as the dimensions of the engine house. He has also photographed the contents of the 3 chambers and the cataract pit.
I'm glad the engine and building has finally been fully measured (I'm surprised CADW hadn't done this already!) and look forward to studying your report.
Mind you, having measured smaller engines and mine sites, I don't envy you the task, it must have taken you a couple of days!
Perhaps you can answer a couple of questions:
1. Is the vertical single-cylinder Mather engine still there?
2. Is the indoor stroke of the beam engine the same as the outdoor stroke?
3. Most important this, as I've always wondered .... is the clock a Joyce?
On some of the other points mentioned, such as moving the engine ... where would it go where it would be safe?
Better to leave it be, less chance of it getting "lost" and various museums have managed to do that!
Wales is littered with examples of neglected machinery, not just the Dorothea engine, the Robey incline engine, and the Penrhyn water balances, what about Glyn Pits, or the Point of Ayr winder - currently lying in pieces in the open, unprotected at Bersham ... I could go on!
