I would have thought that getting the engine to pump water would be nigh on impossible given all the nonsense about health and safety and the fact that you'd have to install pitwork back into the shaft. Would they make some more pump bodies, or would they cobble something together? Where would you get bits of wood that big from and how much would it cost. How would you get them down the shaft, given the headgear is in the way.
My mate Mike and I could do it using a couple of cars tied together, some old bits of rope and a 100m exclusion zone, however the method statements and risk assessments would drop a lung at the thought of this.
I'm not sure what a "condemned" shaft is, but i gather Robinsons is. This probably influences people doing stuff in it at all. Then we have the question of what it is going to pump and where from. Water is about -30m at the moment. If crofty start pumping (sorry, when) it will probably be a "tad" less than this. 600m ish? So, will there be a cistern in the shaft and what sort of risk does this pose (I gather Pool College weren't allowed a biology pond due to the mine).
Even the odd engines which pumped from adit to surface for a variety of uses (Little engine at united) used a fair bit of coal! That wasn't even an 80"
If they are to have the engine moving, I think the best, realisticly achievable (but still a very big task) would be to have a series of dams and a syphon system at adit level, operating the engine via it's pitwork.
The question would be, how much water could the adit system feed and how big would the cisterns have to be in order to overcome friction?
It's a load of coal to get the thing steaming! Is that what the road's for? Do they have a coalyard in the RDA thingy, or has it been replaced by a stainless steel sundial, or a sculpture which celebrates woman's role in creative candy, or something?
NB:- Also, I imagine, regardless of how lovely and romantic this all is, Crofty rightly would probably rather not have some people pissing about with big heavy things in one of their shafts.....also, I forgot, Robinsons has a very sad skip road and ladderway in it which would probably need to be removed before anyone even thinks about anything.
It's probably better that Mr Midas puts a showhome on top of the shaft and everyone gets on with their lives.
