It's a fleeting comment in his first Reith lecture where he mentions this and not doing enough to combat climate change. Surprisingly he also mentions the need to address growing inequality of wealth. I have not listened to the rest yet. It worries me when people at the top discuss inequality because to my mind it's not wealth distribution per se that's the problem but the spending decisions that go with it that effectively means the decision on what to spend money on becomes the province of the very rich and damage to the environment results. I am reminded of that actress from tutiftuity who stood by that pink boat and spouted about climate change and how she wished she didn't have to fly for her work, of course she didn't need to fly at all but she did in order to retain her position as a rich and famous person and that meant she was willing to pollute more. This sort of decision doesn't worry me , people have always aspired to reach the top, but it results from a financial management system, which has out competed all other ideologies, by not having the constraints of worrying about the fact we exist on a finite planet or the external costs to the commons of air, water climate etc. Of course man's ability to cause these global problems has only emerged in the last 150 years and only recognised in the last 40.

Me too but only got 2 days use there before the job was called off because of covid.

Yup, mine too for the little use I have had out of it. @Mick Dempsey the eder 1800 has two speeds but I have only used the low speed high pull one. When you tighten it up for a fell the tension on the tail applies the throttle, once tight and you ease off the tail "falls" into a cleat which holds the tension. I always, so far, leave the engine running until I need to pull the tree over. I also always use the decompression valve when starting. rope wound on capstan with tail running round white pulley which is on the throttle lever, in this position the throttle would be wide open. Here the tail is slackened and the throttle is closing, the rope is laying into the holding cleat here the tail is released and the rope is fully held by the cleat were the live line in tension which I didn't go to the trouble of demonstrating fully.

Hey I guess you're taking a bit of a break while I'm getting a bit bored not getting out and about.

With my granddaughter being grossly over weight I have been pleading with her to take more exercise and snack less but she doesn't seem to accept the advice. Mind I also try and clean for another elderly lady who won't do anything to help herself she is getting worse too. Of course as has been said before our health services have been extending lives of people with underlying health problems into old age so failing to address this disease means lots of people are vulnerable. I mentioned before my primary school friend, 2 years younger than had to be carried out of the house by the fire service as the lady ambulance technicians couldn’t manage. He's 6'4" doesn't look too large but apparently 18 stone. He got home and I saw him, his next door neighbour, 62, died in the same ward. BTW Mark Carney seems to think the government made a decision not to be prepared for a scenario of a pandemic.

Groovy Timber log store surprise.
openspaceman replied to Old Mill Tree Care's topic in General chat
I know what you mean, satisfying that you are keeping the house warm and worrying that you will have to fill it again. In my case I'm romping through my enlarged wood store and we’ve only had a few days with frost, 1.5C out. I wonder if wood will last till April. -
Video comes across as on its side for me, is there a way of rotating a video on a desktop? Anyway I can't help much as I've only played with simms minimec pumps and perkins distributing ones but generally you bring number one cylinder to TDC on its firing stroke (both valves with clearance), normally marked on the flywheel seen through a little window mark the pump across the joint with a scriber and witdraw it, the pump will rotate slightly as you pull it as the timing is normally a helical cut gear. Note the position of the gear in relation to the case.

Looks like you were sending whilst I was still looking up part numbers
-
@Jase hutch may know. Parts diagrams for the quadtrak may be in the manual which is probably a download on the Greenmech site so you could compare part numbers. If the vertical one is cracked I suspect you'll live to regret hoping it will last. From the numbers it may be common with the older 220. The 1928 has three shear bars EC1928-2-31 Top shear bar EC1928-2-29 Lower shear bar CM220-2-31 Vertical shear bar

No but the great majority of them are self serving above all else

Tipping body with under floor tipping gear inc electrics
openspaceman replied to AngrySquirrel's topic in Arb-Trucks
Scattolini, I got a new one of their bodies from @jose when he re bodied his arb truck, Movano IIRC, and my mate fitted it to a transit, only needed to re position the tipping hinges. -
The thicker you cut it the more stress the non radial surface will exert as its face tries to cup. I am assuming the gumtree will have a high tangential to radial shrinkage. There's nothing you can do about that but evenly drying throughout minimises differential shrinkage as the moisture drops below 25% on the outer parts while the inside is still moister.
-
might be worth trying a few bits cut through the pith and avoid any that don't have radial faces, thin stickers and plenty of weight on top.
-
I can see ratchet straps being a pain to use. Why not make the triangle out of wirerope, bulldog clamps and keyhole sliders as a trial then buy a suitable length of 7mm chain.

If you are worried about the legality then anything which is discarded is waste, the EA just have a position statement that allows that virgin timber need not be treated as waste if it is being properly dealt with. Air curtain burners are technical devices and when I last looked, 4 years ago, were treated the same as open bonfires. Mind even though the Solent division of EA told me that I could not use one when we put about 150m3 of whole trees through one over a weekend he didn't come out and stop us. As has been said you need to keep virgin green waste separate from other wood. Untreated wood could be burnt in an exempt incinerator but not painted wood or wood with preservative. There is an interesting little wrinkle that some biomass suppliers were making use of 10 years ago to get rid of treated wood and I don't know if that is still the case.

The issue is much the same as insulating shipping containers; profiled or corrugated steel roofing is a near non existent insulator so the under surface gets cold, worse is that the exterior surface is off the ground and a good radiator, so gets even colder than most of the surroundings. The covered area often contains warmer air than the roof. As warm air holds more moisture than cold air as it meets the cold surface it gives up water to the steel even if the ambient air is above its dew point. So any insulation under the steel needs to be impermeable to air, else the air moving through it gets colder and condenses out in the insulation. Sometimes a thin cloth layer can be used to wick the moisture away or a tyvek layer can be used to prevent the moisture dripping back down and as the roof warms up the next day the water evaporates. When I built my shed I used a profiled steel with 30mm of foam insulation bonded to it, which also has the advantage of not getting scorching hot in the summer.

Interesting and complicated subject, it seems the band between 5.5 micron and 7.5 micron wavelength is the region where no infra red re radiation gets out at all, and that includes absorption by water, so increase in water makes no difference here, as I thought. There are other regions in the infra red bandwidth that currently ~80% of the infra red escapes, allowing the earth to cool, but different H2O types of vibrational directions absorb Infra red in these bits of the window and so H2O increase can still dent re radiation in these bands
-
Yes, I skimmed through your link and the positive feedback resulting from non permafrost releasing methane and peat bogs respiring CO2 as well as wildfires but was not so happy about the claim that as things get warmer more water vapour will be in the atmosphere (it will) and trap more heat from leaving the earth. My understanding is that all the wavelengths of infra red re radiation trapped by moisture in the atmosphere are intercepted already so adding water will not trap any more.

We'll have to see what @spudulike thinks, I've never taken a saw that new apart but until the rings bed in there will always be some excessive blowby.
-
Those rings aren't even bedded in yet. The spark plug is a tad lean of perfect to my mind but not far off. I can't explain the marks on the piston if it's not sawdust.
-
They don't say why there is less grazing, once that reduces trees can get away. Yes a warmer environment will mean trees can survive in higher colder places but here the point is once they start growing there is a positive feedback effect. Trees absorb more light, which turns into heat, as snow does not settle on them, flat land covered in snow reflects the light back out to space. The article suggests the increase in heat caused by the trees changing the earth's albedo at this place outweighs any benefit the carbon sequestered by the trees gives, hence making the earth warmer and increasing the ability for trees to grow further up the hill.
-
Remember if you heat it it will lose a lot of that energy through the steel wall. If you add insulation to the outside the roof will need to protect the extra width. If you insulate from the inside you lose space but the insulation has to be totally vapour proof, else warm moist air will permeate the insulation and condense either in the insulation or on the cold wall and eventually run down the inside and cause problems, including rust.

A long time if roofed and jacked a few inches above ground away from vegetation.

Can you explain what it filters out, sizewise and how long the filters last, or are they cleanable?

I think something is lost from timber as it gets very old, I have burned stag headed oak (remaining heartwood only) and it is very coal like to burn with no liveliness despite being around 20%, as you say even recently felled and seasoned oak is not as lively as something like birch, or holly as I am finding this year. I attach a picture of a drying experiment I have posted before, as you will see oak dries similarly to other species with birch being the quickest in my samples. The pine and elm I added later as I came across them and by then drying conditions were better. Bear in mind these are individual logs on a shelf rather than in a stack and cut to ~10" and split with initially a weight around 1kg. So I think logs cut and split ready for the fire, under cover, with reasonable air circulation will be below 20% wwb by the end of a summer season . Then they will be in equilibrium and in my case will pick up a small amount of moisture as winter progresses. Logs dry by moisture leaving the surface, as this dries moisture migrates from the inner parts to get back to an equilibrium, so there is a gradient of moisture from inside to out until it reaches equilibrium with the ambient air, in my case rising to about 17% wwb by late winter. The time it takes is dependent on the length and cross section of the log and as moisture moves more readily out of the ends a shorter log will dry quicker than a long log of the same size.
