I don't know about Stubby but I would always pick some up and eat them as I went by, they fill out nicely in a mast year. Someone told me they were poisonous but no ill effects with me and one of the chewing gum manufacturers had a beech nut flavour.

"As I understand it" because I am not qualified in domestic instalations

Definitive answer is in Appendix E of building regulations Part J which is available online. Smoke test with stove and flue exit sealed and flue pre-warmed AIUI.

Have you tried Lamberhurst engineering, they used to be dealers after Hyatt Adams packed up, mind I haven't bought any spares off of them for over 30 years.

You're a dab hand at this aren't you?

Not only brickies, research Ronan Point and missing bolts. I had much trouble with second fixings; vapour barriers and cold bridges on a couple of refurbs at work.

No not if the damper and air controls seal well. It's all a bit speculative with the details and description here, as mentioned you should have a CO monitor in the room in any case. Hold a burning taper near the stove when it is cold and see if a draught flickers it.

There doesn't need to be an extractor fan (good call though) if your house is warm enough to create a circulation from the room your stove is in and up stairs and out somewhere the hot air leaving has to be replaced and cold denser air pushing down your flue could do that.

Yes that was my thought by the texture but I cannot remember seeing any black lichen on trees, round here the air was too polluted for many lichen so I used to see it mostly in the west country.

Does @Ruskins Trees still post here? @dumper is right it's not just the size of the rootball it's holding it all together so the smaller root hairs don't break.

I see so it has happened again more recently. I would have liked some nice beech logs for next year, I have a m3 from the canal centre at the back of my logshed behind all the cedar which burns a bit fast. There was a fallen beech at the same spot earlier in the year. The canal always runs out of water in the deepcut section by June so you can only move around between there and greywall in the summer.

Deepcut by the broken sewer? I wondered who did it but didn't walk that way much in the last year and now the boat is sold.

you spoiled it by not using a seasoned cast iron skillet

I believe they should be segregated from pedestrians and still carry the forfeit-ability of a car or motor bike licence for dangerous use or without care or attention and mandatory road traffic insurance, especially if they exceed 15mph as most seem to.

Fine by me as long as they keep them off the footways.

Yet there have been a couple of posts here where people have admitted running the battery saws out of lubricant because they forgot to top it up. I only used one of the earlier top handled battery saws I bought very briefly, just to see if they worked, we bought them for night work.

good maths and it's also better than that because you will be reclaiming 20% on inputs, like petrol and diesel.

Yes some interesting kit about, I wonder if that would stand up to forestry work. In my browsing I came across this: Which is ingenious in that the carriage is geared to drive the fan much faster than the pulley that is running on the cableway. As the power absorbed by the fan is proportional to the cube of its rpm (IIRC) it hits a terminal velocity. This is similar to the air governor in those swiss musical boxes. Anyone who has tried winching stuff downhill off steep slopes can understand how an uncontrolled log slide can be dangerous but this would limit that. In principle the cableway could be slackened to attach the load and then tightened to lift the log and away it would go, with perhaps a control line on the back end .

I've made a pdf but it's 5.5MB so a bit large to post here, PM me and I can send it.

I wonder how much of that is from people running the oil tank dry.

There are 3 more pages I can image but they are mostly accessories and how a dual capstan winch works. I was very keen on these dual capstan winches but only ever came across them for cable pulling underground and tensioning power lines by Plummet when they were in this country by Knepp Castle, frightening cost. The only ones I physically touched but never got to use were the Nokkens on LR101s (mine was not so equipped)and a complex Plummet made under licence by Warburtons and fitted to the military engineering Samson CVRT. The reason for my interest was for a bit lighter footprint than the logbullet type device by using their unique constant force in a novel, simple to erect high lead and locking carriage.

I'm glad you posted that so I could be on an earner. I rushed home and searched my bookshelf with old advertising bumph I had picked up at shows but became rather dejected when I couldn't find it. I may still have it somewhere but it may have gone in a fit of tidying up. @AHPP Whilst searching for something entirely different I came across this filed away somewhere safe

About 15 years ago I saw a blackbird sitting eggs in a hedge abutting a university building in February. I assumed the warmth from the building made them start early.

Yes but there is a history of human deeds to solve one problem but leading to another. I don't necessarily disagree and we should be reducing our need for power from burning either fossil or biomass fuels, they both emit carbon dioxide. The thing with trees is that they maximise their photosynthetic out take of CO2 from the atmosphere in their early life then at a point they change from youths to adults and this growth tails off even though they can live for hundreds more years and store the carbon. So, as with sylviculture, it will pay to harvest trees regularly and maximise the conversion of sunlight to wood and then store the carbon in a recalcitrant form. Without spending time googling to confirm this but I think the major carbon stores are in the sea as clathrates, in the earth as carbonates (like chalk laid down as skeletal remains of small marine creatures) and in the soil as humus and peat like substances as well as vast remaining stores of fossil fuels. Peat and clathrates evolve methane and CO2 as the earth warms. The interesting thing is we cannot just bury biomass and hope it turns into coal because coal was formed at a time before a microbes to decay lignin had evolved but now ultimately buried biomass will get recycled to CO2 and water whereas carbonised wood will not.

I worry about the unintended consequences of geo engineering which is why I'm keen on biochar as a means of encouraging photosynthetic activity to gradually solve the excess CO2, of course it won't work until net carbon zero is reached and the places where it is used are rewarded.
