I fabricated a tractor exhaust last year, on site, with a 200A inverter welder using a 3kWh 3kVA power station so I don't see why that wouldn't run a 2kW corded chainsaw for ringing up, mind you would need a wheelbarrow to carry it (and £3k)

I was thinking that it would have to go through the legal department and the chief executive and that even an unopposed TPO would run into thousands

How much does it cost to TPO a tree?

Knots and inclusions will militate against selling it for sawlogs or bars plus you will need at least an 8 wheeler load of 17 tonnes for local delivery or 29 tonnes for an artic flat bed.

So there is no continuity between spark plug lead and ground on the coil? I suspect the 285cd was just a slightly larger engine than the 280cd and the coil may be common to other saws and stone cutters of the era, @adw will know and would have worked on them nearly 50 years ago when they were new but he may not read this message till after the bank holiday

If you were a commercial feller the cut would have been at ground level and the butt a bit longer.

Nice short butt, saw just a tiny bit short too.

testicular cancer, the first recognise industrial disease. I think the same PAH as was linked to lung cancer from cigarettes.

That's about the same number of years as I was taught in my geography lesson circa 1963, much the same was said about copper. Still I take the point that, plus or minus a few decades, won't alter the fact that with homo sapiens having existed for a few hundred thousand years and worn clothes for about a100 thousand years the exploitation of these fossil fuels, and the changes to the ecosytem that have resulted, have taken a blink of the eye in comparison.

No different from most cargo shipping and whilst they burn a particularly polluting fuel the carbon footprint per tonne of goods is better per journey than road transport. Spent batteries and micro plastics from tyres is not something I have followed. The grease I use in my tractors is lithium based, no idea how much, but I don't recycle that. Nearly all hydrogen is made by reforming natural gas. The round trip efficiency of making it from renewable electricity would be low, about 70% at point of production then only 25% of that is available as power at the wheels from a heat engine, there is nowhere near enough surplus renewable electricity for it to be viable. Even if there were a surplus it would be better making more easily transported and stored fuels. Whereas the EV gets 80% of the electricity put in delivered to the wheels and is even more efficient as it can regenerate when decelerating and doesn't have to idle. I still use my petrol and diesel engined cars because they have plenty of life left in them ( at 20 and 15 years old) and I don't do enough traveling to lash out tens of thousands on a new car.

arboricide according to W.S. Churchill

I can see there may be good reasons not to be involved with cutting but those lower branches are going to carry on growing outward and will make access by any vehicles difficult over time.

Could it be the alternator regulator voltage too high? Maybe put a diode or two inline with the solenoid

Yes an if you look at our current demarcation area You will see it all in the dry eastern part of the country. It has long been known that spruce does less well here than in wetter parts, so spruce will be more stressed here during a summer drought and probably should not have been planted. It may have been that the then much vaunted, highly subsidised Shotton paper mill that opened in the early 90s persuaded woodland owners to plant spruce but as with poplar for matches the mill closed before the trees were ready. I harvested thinnings of spruce within this area, normally planted in line mixture with oak, and occasionally would come across a live tree that looked little different from the rest of the spruce but was peppered with resin tunnels where the tree had tried to drown the insect with resin. As a relative newcomer to forestry in the late 70s I had it explained to me that insects were far better at finding a stressed tree than we were. My manager in 1974 told me it was then company policy not to plant spruce in the south east. Yesterday traveling south on the M23 just north of Pease Pottage I could see what looked like sparse spruce crowns.

"petrichor" formerly known as "argillaceous odour" I like "argillaceous" the way it rolls

yes that smell of summer rain needs a name

I would try it but for this, I wouldn't know when to record

Funnily enough, and apart from the way she set about it, it was the only good thing I think she did. The worst thing was the moving of the social housing stock into private landlords' hand and enriching her banking sector friends at the same time. The second worst was going with Keith Joseph rather than Goldsmith over GATT.

Plus for short term forecasting the rain radar map is pretty good

Might as well bury or cover them to stop algal growth. I got the submersible pump out to pump water from the capped well into two butts today as they were dry.

I wonder what insider trading was done

Even my chinky cheap one would do that, especially if it has been cleaned a bit. I would not attempt doing anything to it with a saw unless I was determined to split if, then I would do some deep plunge cuts from the top face and hammer some wooden wedges it. A very long spade bit drill is easier to sharpen than a chain if I wanted to get through it. The thing is a stump is a higher quality wood and interlocked grain because it has to resist all the motion the stem transfers to it without splitting.

Yes but it doesn't explain why ; either it's because the cambium isn't thick enough to support a breeding gallery or because it becomes too dry for the grubs. Back in the day when Thetford pine was coming on stream ( probably before the FC moved from scots pine to higher yielding corsican pine) there was a roundwood depot at Brandon. All the surrounding pine trees were stunted from chronic attacks from pine shoot moth (IIRC) that had bred in the timber stacks.
