A shed day :-)

Three AM, well almost, that’s the cup of hot chocolate and banana demolished so I’ll plonk away on here until sleep (hopefully) once more creeps up on me. Well, it really was a pure 5h1t of a day on Sunday. For all it’s ferocity the wind only generated 19kWh, which when you stood outside and listened to it is hard to believe, but that’ll be a southerly wind at Sonas for you. The storm is driven off the land, it’s friction taking the sting out of it and despite hardly being able to stand up in places there isn’t much energy in it. A common misconception when siting a wind turbine and why they NEVER work on roof tops or in urban locations.

You need that ‘smooth laminar airflow’, the H in the diagram refers to the height of your turbine, so the best air flow is 20 times the height of the highest obstruction away from it. For me that means anything from the east is abysmal and the south poor. Had yesterday’s direction been in the west or northerly quarters I’d have generated two or three times that. The prevailing south westerly not being far behind, still there was plenty of water driving the hydro which double production to almost 40kWh with a paltry 2 or 3 kWh thrown in via the solar panels.

A lot of effort

In short, it was a perfect day for ‘in  the shed’ repairing my ‘Britpart shitpart’ radiator.

The bottom mounting of which was pure rotten, rendering it likely to fall apart at the first bump in the road. This bottom mounting is actually quite clever, being designed in such a way as to allow for the differing rate of expansion of the aluminium core which makes it very difficult to repair. The obvious way would be to try and remove it and weld it but any strengthening is likely to cause grief once it has heated and cooled a few times. Also being attached at the plastic ends with six captive bolts means a great deal of care is required in removing them.

Unable to apply any heat I just carefully tapped them with a small hammer to remove the rust and eventually managed to remove 3 of the 6 with a hexagonal socket. I then searched my scrap pile eventually settling on a piece of aluminium plate some 6mm thick that had come off one of Hallaig’s sliding fire door surrounds Smile As the aluminium plate has the same expansion rate as the core I was hoping it would provide the strength required without compromising the core’s integrity.

I cut a bar out of the plate then heated and bent it to the shape of the radiator base before drilling and filing out the three mounting holes.

I then put long bolts in with thread sealer prior to chopping off the heads and cleaning them up. In retrospect I should have used short screws with countersunk heads as the new nuts fouled the radiator/intercooler surround captive nuts, this I sorted by grinding them off and welding the bottom corners of the frame. After that it was a case of cleaning up and painting, though I still have to sort out the top right hand corner, but that’ll be a job for today. Good job I wasn’t paying myself by the hour, it took me just about all day Smile

Awesome halibut

Well, not quite the whole day, my dear wife came to visit me and we made a lovely lunch or should I say I bunged some sweet potato strips in the oven and she grilled some halibut in mayonnaise, harissa cheese and spring onion.

Right enough, I did cover the sweet potato in olive oil, salt and chili flakes first but it was the grilled halibut that was the star of the meal Smile
