Do you have buttered scones for tea?

As I said wood gives off volatile organic compounds, they give it its smell, these compounds react with oxygen to break down and one of the products is CO, CO2 is also formed but as it is not toxic its not a problem. Pellets are made with fresh wood, this gives off more VOCs than aged wood, they also have a very large surface area and their dust makes more, so there's lots of substrates for reactions to take place. It's likely these VOCs and other volatile solids that the microbes eat and make a woodchip pile hot, after a while the heap cools down and in the same way over time the pellets would stop producing CO. It came as a frightening revelation to me as a firm I snagged boilers for fitted a pellet store which contained 20tonnes in a 2 storey room above the boiler, Above that was the control room and buffer tanks. The manhole above the pellets was not sealed and potentially I was exposed to CO when I was working in the control room. I was only there a few hours but worse was that the control room opened out onto a landing with 3 flats. This was a prestigious development opened by the London Mayor but like many green initiatives it went tits up after 5 years (long story) and the pellet boiler was ripped out and gas combis installed in the twelve flats.

We seem to be having differences today Saul. CO2 can be given off from a number of pathways but it's not toxic unless it has displaced all the oxygen. CO is lethal at 0.3% within 30 minutes as it binds up all the haemoglobiin in the red blood cells.

Me trying to interpret your hieroglyphics the first of which appeared to be somewhat effeminate

I can go right off people WTF do they mean please support girly's blouse?

As Gary says there are not likely to be high levels of CO2 and there will be oxygen present so asphyxiation is unlikely even in a recirculating kiln with no fresh air entering. In sealed ship's holds there have been cases of the air being used up by microbes living off the wood and even with extremely dry wood in pellets lethal levels of carbon monoxide have built up where the volatile organic compounds have only partially oxidised. The other case where people have been asphyxiated is in sealed grain stores and possibly silage towers where all the oxygen has been used up by the respiration of the grain or microbes eating the silage. CO detectors are cheap enough if you are worried.

Because the tree can better react to wounds while active. In this situation it becomes a bit like a hedge which needs a couple of trims a year. The owner of the adjacent property has the right to remove anything trespassing over the boundary so the tree owner has no say in this. I suspect the tree owner will only have an issue if the "trespass" becomes actionable, by damaging the house, at which stage the costs of abating the nuisance will be down to him. If the adjacent land owner isn't happy to keep trimming then I agree with MickD and stihlmad

That was my thought too but would still think summer pruning was better.

I've not seen a chip fired one but if you have 9 grand to spare Thornhill do a pellet fired one. In principal there's not anything special about a chip stoker, Veto used to do one that slotted into a combustion chamber at the larger scale. A pellet burner burns chips fine as long as they are dry, the problem is that the auger is too steep in the ones I have seen to feed the chips without jamming (this steepness is to allow a long drop into the fire pot that acts as a fire stop).

That'll be Huddlerafield, Sussex from your profile

I worked with a nifty lift 2.5tonne 17m mewp last week, it had hydraulic caravan movers and a small diesel motor as well as the battery electro-hydraulics, it moved at no more than 1mph and wouldn't handle gradients (though it did better from cold so I suspected a warn pump). Fine for local positioning but useless to track into a site. I would expect a 25hp engine would be just about adequate on a small chipper.

So they'll be the right way up when the world ends? Elm is classed as non durable I think but you could drill a hole up the trunk and set it on a length of scaffold pole which wouldn't be seen.

You owe him double time then ?

Just water in a kid's water pistol knocked them off my pepper plants. A pressure washer stood back just far enough to knock them off would use very little water.

A ford 4000 with half tracks (chieftan forge I think) would get places the county wouldn't

I held on to a pug XD2 which I had had rebuilt just before the 504 pick up was written off 20 years ago just for this purpose. I finally decided I wanted the space and put it on ebay yesterday. I wore a hole in the sump which must have got rusty, dragging it across the floor for photos and it dumped its oil on the floor.

You should be aware that most flow control valves dump the excess flow across the same pressure as the active service so they tend to heat up the oil much as passing the full flow to a service. It's no big deal until the flows get higher. We had this problem with the County crane becoming too difficult to control when the PTO ran a chipper if the pump was big enough to load with during normal use.

Yes we were talking about the same thing, crown thinnings in forestry is when you free off the crowns by removing more than thin and suppressed stems, so also taking co dominant trees , what you need to create gaps is selective felling.

The point being that the sycamore will respond to the increased space from a heavy crown thinning more than a new planting will, which means more intervention needed during establishment. If it were a glade 30 years ago and the sycamores are still growing...

Have you a link? I use diamond files for honing blades, not tried a round one on a saw, but would not have expected them to have enough stock removal for most chain sharpening.

Not much worse than a tirfor and you can change the gain with the log diameter. This is very handy for take downs in early thinnings when they are too big to pick up the butt and run In principle you can do the same with metal poles joined into an L shape

Maybe start summing up what the loss of saw has cost and starting a claim for damages

May as well put a battery isolator in then, good precaution in any case

You can if you squeeze the water out when a tap is open

How much did the BCO charge for the inspection?
