Yes, look at this one, the nearest ring is badly worn as shown by the wide gap, the one underneath near the top of the cylinder is the new one with the smaller gap. @adw is most likely right and the very hard but thin nikasil layer has worn through. This rarely happens with chainsaws but disc cutters work in a much dustier environment and I have no experience with them.
-
seeing as you have got the ring offer it up to the cylinder and square it in the bore with the piston and using feeler gauges check the gap in various places.

Yes, my home is by no means damp, I live in one of the driest regions in UK, going room sealed is probably the only way around the regulations with a bigger stove but drawing air from the room and a whole house heat exchanger makes more sense to me. The solid wall brick built with lime mortar eveolved over a long time, the walls need to breathe both sides so I am loathe to attempt insulating them, inside or out. I do wonder what effect wall hangings have as you see them in colder places of eastern europe. Modern build methods, done correctly which is the exception, may be the way to go to satisfy people sitting on the M25 but knocking down a 160 year old house and starting again is not an option. -
Yes It looks like it has never been repointed on the exposed brickwork but the hall is a single storey extension from 1959, still solid 9" but rendered.

72% RH in my hall now and it has been a dry warm day after previous rain., so a fair amount of moisture in the air increasing RH as it cools to 9C outside. Once the stove is lit it will hover around 40% RH when the temperature differential gets above 10C

I live in a fairly basic draughty house but do have modern double glazing that seems to seal well but some of the windows have vents and bedroom windows generally have a top pane at least slightly ajar all the time. I have a nominally 4-5kW stove drawing air from the room. Air changes per hour differ between rooms but ~ 7 changes per hour recommended for a living room. This little room is about 3m by 4m by 2.4m so needs about 200m3 of air per hour. To get 4kW of heat, excluding flue gas losses I need to burn about a kilo of 20% mc wwb wood per hour. The stoichiometric air required (to react perfectly with that amount of fuel) is 6kg or about 10m3 of air from the room, in practice most stoves will supply 150% to 200% stoichiometric air, say 20m3/hour.

I am much the same

I'm not too sure about this because I think you could bend the crank on an original 262 by pulling it when it's been jammed in the cut, and not snapping the chain, later ones which could take the 3/8 chain had a stronger crank. It's an old memory so @adw may remember better. A chain run out of oil gets very tight, there was a recent post about a makita that had to have a new sleeve put in the crankcase because the bearing housing was oval and I asked if that ovalness came from it being yanked hard.
-
but did you measure anything, like the ring gap at various parts of the bore. Air has to be escaping somewhere for that low pressure figure.
-
Not really but I wouldn't like to lose the ability to only see unread posts initially
-
Well actually some of us didn't initially , and I'm talking well before FISA, but the association was usurped by the wrong people at the top who essentially sold out to the industry knobs.
-
Yes I believe so and it was perpetrated by the bigger industry moguls with the collusion of the FC in order to prevent small players challenging the status quo.

Yodel delivered a battery to me a 055 from numberone batteries, filled, but it did have transit plugs in.
-
Yup
-
Yes tolerant maybe but not thriving and plainly showing deficiency symptoms yet WRC are doing fine. The site is an SSSI so a bit restrictive with what can be done, when planted it wasn't so.

I was extracting on a chalky hillside today and took this photo of a Corsican Pine (I think) you will note the yellowing of chlorosis but it is hanging on amongst the dying ash. I noticed one other corsican in the block so my guess is they were planted in mix with beech in the middle of last century. I expect there was a planting failure of both the beech and the pine and ash took advantage. The beech have subsequently been hammered by squirrel damage but elsewhere on the site is some very nice western red cedar. The ash is badly affected but there are individual trees that show remarkable resistance. Because of this I was keen to remove as many of the plainly dying ash in winter 2019-20 in order to reduce the spore load but this was not done.

The manual will be online as a pdf on the greenmech site else I could email a copy this evening
-
I don't know, how are you going to keep it small, bonsai techniques?
-
That would probably not allow the root system to entrain enough soil for stability if the tree is allowed to mature

That's right, all the time heat is cheap the extra capital cost is prohibitive unless done very cheaply. Also the higher the temperature of the kiln the more worthwhile it becomes, Have a look at the simple plate heat exchangers that are in discarded condensing tumble driers. The thing about these is they recoup some of the latent energy in the warm saturated air which is significantly more than the energy in the hot air itself. The trouble is the massflows of fresh air and exhaust vapour don't match so unless the kiln is hot and you have something you can use the lower grade heat for.. . What may work would be the kiln inside a poly tunnel full of wood waiting to go into the kiln, so a modicum of dying from the larger massflow of the condenser heat exchanger is usable

Just look at the size of soil pits used in urban planting in surfaced areas of development sites often 3ft deep and 15ft diameter for "forest" species. As to rooting depth this is a picture of a 25 year old thorn I have just pulled up from my garden, ignore the ivy that came up too.

... or a good investment?? Money and value are amusing concepts. Whereas the most of us aspire to own things we can use I'm sure some people derive pleasure from the knowledge that their wealth prevents others enjoying it, a sort of schadenfreude. The recent discussion on housing costs and subsequent revelations of pandora is a case of how supply and demand are skewed by investment opportunities. A finite housing supply that is attractive to inward investment drives up prices, price increases driven from demand from home desirers and foreigners wanting a safe investment means rental income is less than capital gain, so properties left empty.Then purchase the property by a company registered elsewhere and you avoid UK taxes too, a double whammy for the UK resident.

easy enough to check the soil pH with a test kit. Also iron sulphate will drop the Ph if you keep an eye on the level regularly.
-
I think most pines like slightly acidic soils, which is why scots pine invades our lowland heaths which are sandy and low Ph. Would you consider western red cedar?
