Life at the end of the road

The frog filter :-)

To be honest the thoroughly miserable day that was Monday the 4th of April was perfect for what I was doing today, well so long as you exclude walking Bonzo but he didn’t seem to mind  the rain. Which was the first thing I did after my third cup of coffee and updating the blog, after that it was into the shed to construct a filter for my Mate’s Harris turbine intake.

The turbine which draws water from a loch down a 63mm MDPE penstock some 700m long with 90m head only uses a 4mm jet and very little water to produce enough power to run his house. However of late we’ve been experiencing a frog epidemic. Well three or four blockages in as many weeks and as we’ve only had three or four previous frog or newt blockages in 12 or so years I reckon a new filter was needed. The original one being made from a steel quarry screen for riddling fine stones cos it was all I had at the time. I had intended it to only be a temporary measure so it was about 10 years overdue changing anyway. Sadly the one I spent all morning making is in a similar vein as I couldn’t find any stainless steel so had to settle for some 1mm perforated galvanised steel with 2mm holes. However this time I WILL order some of the right stuff Smile The piece I found just needed trimming on one side to make it 500mm x 1000mm, my original plan being to wrap it around and weld it to some old brake discs that would ensure the filter didn’t move.

However I quickly abandoned that idea when I felt the weight of it and realized I’d be carrying half a mile over a hill Sad smile Instead I used a brake disc as a template to cut two ends out of an old piece of ‘stock board’ a materiel made from recycled plastic that’s used in fish farming and agriculture. Its about 13mm thick very durable and easy to work with woodworking tools.


Once I’d had my lunch I donned my dry suit, loaded my filter and tools onto the back of the quad and headed to Torran.

My first stop being the turbine itself which I intended to switch off, but alas it had claimed yet another frog since yesterday Sad smile I turned the valve off anyway and took the perilous path up to Pipers Rock.

Well I never used to think it was such a big deal in the past but with age one gets more cautious Smile The normally spectacular views of Skye, Fladda, Loch Arnish and even Dun Caan and the Brochel lochs being lost in the murk. Even the houses and crofts of South Arnish being shrouded in gloom. Leaving the quad by the boundary fence I loaded my gear and set off eastwards along the fence toward Loch nan Dubhan. The weather may have been miserable for photography but in my diving suit at least I was dry and not sweating or overheating as normally would be the case.

I thought I had it tough

Not far to the east of the gate there lies and old sheep fank complete with a sheep dip dug into the ground and lined with stone Surprised smile

The dipping trough itself is just east of these two pens

the sheep would be herded down between these two walls down a slope into the dip.


You can still see the stone retaining walls and base but the nearest water available to fill it would have to carried in buckets several hundred yards Surprised smile Thinking about that I grabbed my filter and walked off to the loch thinking how easy life is these days compared to back then.

My task seemed a lot less onerous and pretty soon I was in Loch nan Dubhan fitting the new filter.

P1000769 P1000770

The old one having rotted away completely Surprised smile

P1000772 P1000773 P1000774

Then it was back west to the quad past some remains of the old boundary wall that existed long before the fence I was following.

Once at the quad I set off gingerly down the hill and turned on the hydro turbine before heading home to feed the dugs whom I’d left behind for fear of loosing control on the track up to Pipers Rock Smile
