Friday 20:30 now and little chance of me finishing this tonight but I’ll make a start, it’s been quite a productive day really considering the leisurely pace I’ve been working at. The main job being work on the Proven/Kingspan wind turbine tower foundations. The 6kW wind turbine that I’ve been working on these last few years is at last coming together, though not without its hiccups.
First job this morning though was to take Molly for a ‘wee wander’ over the hill. Truth be known it was so I could try out the new camera, though it was hardly great weather for that. The rain was never far away and the wind and low light not conducive to great camera shots.
An old wall and shieling behind the and another ruined enclosure being just a couple of the many signs of a more populous time here at the ‘North End’.
Loch Arnish and the ‘wee dug’, not much in the way of colour up here at this time of year.
You can however see just about everything,
two Tamworth gilts eating their breakfast for one, a long way off and a bit blurred but that’ll be me shaking in the wind
The two Proven turbines at Arnish,
Torran Schoolhouse, Calum’s house, and ‘Number 3’ https://www.airbnb.co.uk/rooms/8188794?s=3LQkEta2 . A bit on the fuzzy side for the far away ones,
like Torran, but it is a very long way away!!!
This will be Fladda, which is even further away, I am much impressed with this Panasonic DMC-FZ72
There I was ‘Diggin’ this hole’
Next came the serious business of digging a hole for the big turnip. I thought long and hard about where to put this Proven 6kW and it’s been a bit of a compromise, by far the best place would be where the 2.5/3.2 is now or somewhere up there. Trouble is you cannae get a lorry up there with the concrete. There’s an even better spot right in front of the house but much as I love wind turbines I like my uninterrupted view out the front windows better.
A good compromise was just to the side of the house
but that was as far as I got before coming into contact with solid rock What I was hoping for was to get down just less than a meter or so.
I was hoping to drill and pin a few girders around my homemade base, weld the lot together and set it in a few cubic meters of Readymix. Well that plainly wasn’t going to happen so I resorted to ‘Plan B’, which was just as well cos that’s where the planning application is actually for It is actually a better spot in may ways as I knew there was a clay hole there. It’s more out of the way, nearer power and it means I can ‘drill and pin’ the winching eye into Scotland. Other sites would have meant another couple of cubic meters of concrete for the anchor.
This site has some very nice and solid exposed rock perfectly sited nearby, it is however not quite so exposed as the other potential sites.
Sat inside Calum the Kubota I soon had a 3M square hole dug and some nice bedrock at around 1.4M. Not the nice fracture free stuff that I’d have liked but stable enough to drill some nice deep 24mm hole in for some M20 threaded bar. Much easier than Bernard’s ‘ole
Apart from tinkering with the neighbours genny and repairing a puncture on my trailer that was about it for Friday. The good hash of wind and rain through the night had topped up the battery banks, not to mention my ‘ole
Though the trusty 30 odd year old Honda 2” water pump soon had that emptied.
I then promptly started filling it again, this time with clean water under pressure to wash off the exposed rock.
I then drilled half a dozen holes 300mm deep and hosed them out again prior to injecting them with Hilti HIT RE 500 resin.
The holes were drilled at various odd angles and constantly washed out with clean water. The resin doesn’t mind water but the holes must be scrupulously clean.
That done I set about rescuing various bits of rebar and reinforcing mesh out of the long grass
Tomorrow will hopefully see me getting some girders welded together and dropped in the ‘ole. Me reckons it’s about 2.2 x 2.4 x 1.4 so around 7.3 cubic meters so far but I’m gonna raise it a little with some shuttering and aim for 10 cube. Proven/Kingspan/ Hutchinson reckon 10.3 but Eyre Plant’s batching truck can’t quite manage that, hence the drilled and pinned rock.
