As they say "every day is a school day". I knew the face was compressed, I knew the bat was oiled with linseed but I was unaware of "knocking in". I'd still like to see what affect it has on a poplar board.

I was thinking more in terms of how many neighbours overlooking the tree would be needed to make it a " public amenity" if it weren't very visible from a public highway. ...and if they didn't object to the tree being removed?

This is what I often wonder about TPOs, how many people have to be able to enjoy seeing them before it becomes a public amenity in need of protection?

Last time I was there we were stuffing all their offcuts and waste through a Heizohack. I definitely did not know one had to hammer a cricket bat before use.

It's not my game and when I did play it 60 years ago at school I certainly did not appreciate how the surface was hardened, I thought it was all done in a hydraulic press once the bat had been made. I did sell a few cricket bat willows to a firm in Bedford. The question is: if surface hardening is done on willow so it withstand the thwack of red leather why wouldn't the same process harden poplar boards for a table top?

That was just testing how hard it had been done in the press. Small world of treespanners

If you're growing there it means you can monitor the weed, glyphosate will deal with all the aerial bits so it will not interfere with your tomato plants.

Punctured float?

There was a market garden both my parents worked at before my dad volunteered for the RAF and they planted a poplar grove with the intent of making vegetable punnets but then plastic came along and latterly the place became a F1 headquarters and supercar factory but the remnant poplar coppice is still at the front. Forest Fencing had a peeling line as did the aforementioned poplar Timber Company but I don't think this last was commissioned. The problem with poplar furniture was it dented easily. I wondered if this could be overcome in the same way they surface harden cricket bats, by crushing the outer layer, to give a tough surface and a light rigid core.

Yes, I wonder how many people get buried nowadays, a simple coffin must be advantageous for cremation. . We sent a few lorry loads of good butts in multiples of 7ft lengths up to a mill in Towcester so they must have had a market. Of course George Snell used to promote it for furniture but I wonder what happened after his firm morphed into a biog firewood business.

Sorry I missed the "expand the most" without reference to other metals, answer is I don't know but O level physics taught me invar expands the least ?

"but scientific studies indicate that the average global volcanic output is insignificant when compared to emissions from human activity. " ...being a significant quote about CO2

Brazing rod onto a steel strip is probably the easiest

yes that's already a given understanding and it will be highly dependant on how long the infestation has been established and the type of soil. As I said it had to be excavated to 4m and reburied in a plastic lined cell below this at Olympic Park. One of the things about JKW is the way it reacts to a systemic herbicide like glyphosate. The rhizome that stores its energy resources is sheathed in meristematic material, this is like our stem cells in that it is undifferentiated so can form any organ. The shoots are differentiated and cannot change, so they absorb the chemical via the leaves and translocate it to the rhizome. Only a limited amount of chemical gets to the rhizome and it only kills the meristematic tissue in a small area around it. If it hasn't killed enough to finish all the rhizome then the unaffected meristematic material is available to form new shoots, if triggered. In some situations this means it becomes next to impossible to kill the whole underground plant completely. Of course you never know if you have succeeded unless you observe it for the next few decades. Bracken is similar in this respect.

Coffin boards was the high value market. It looks like that tree has been high pruned

Yes and look what effect it had on the globe. Man's contribution is of course additive and for CO2 it is larger than volcanoes but still a small part of the total exchange between earth and atmosphere. However the net effect is that for some reason the natural cycle has not been able to buffer the increase as I expect in my youth. Ordinarily I thought increased CO2 would stimulate extra photosynthesis, and it does, but overall other factors counter this such that the CO2 from fossil fuels stays in the form of an equilibrium between the atmosphere and the surface waters of oceans, about 45% of the increase bcoming carbonic acid in the oceans. Now given marine skeletons are a massive carbon store, in the form of chalk and limestone, and require a slightly alkaline environment to form plus the fact that anthropogenic heavy metal contamination of the oceans has a disproportionately very large effect on bioactivity and we can see a couple of reasons why excess carbon is not being removed. So the effects of excess CO2 are not only affecting the climate and the simple fact that photosynthesis is such a huge fixer of carbon makes me believe that sequestering carbon in an inert form by intervening in the growth to decay cycle is likely more benign than other proposed geoengineering solutions which strike me are time bombs.

I did not know that. Mayflower was the first winch on the series 2 I cam across, the capstan one but they also did one driven off the centre PTO, a drum winch. I only ever got to own the Fairey free wheeling hubs.

They can be carbon negative if turned to charcoal and buried.

Where is that?

I've said this before but be very careful opening your eyes first thing in the morning. The healing that goes on when you are asleep is very fragile.

We used to have little trouble with the Stihls but there was an issue if someone fiddled with the HI setting in that IIRC (and it was a while ago and memory is getting a bit unreliable) there was an ignition rev limiter. If it was tuned rich the limiter still cut in but with the throttle wide open unburned petroil carried through to the exhaust so that oil condensed in the exhaust. A similar problem frequently occurred with the BT45 drill which had a spark arrestor and if this was used wide open throttle between holes the gauze blocked almost completely. Not a problem that happened with a sensible operator but a weekly problem with utility or rail arbs, easily solved by unbolting the spark arrestor and burning oil off with a blow torch. I always put them back in as they cut the noise but I know others cut the gauze off.

Yes this is about what I use each year and use just an axe over a few days in the spring even though I have a small processor and cone splitter rusting away somewhere, I don't think the neighbours would appreciate industrial activity in my garden.

Well I suggest his fire just didn't get hot enough. Never transport it offsite to deal with it. The idea is to get all parts above 90C to kill. Dry superheated steam sterilisation has been used in hot houses for years to kill off persistent pests. Thermal input need not be as bad as you think, especially if the soil to be treated is dug up and put through the treatment plant, in situ is an interesting challenge which I never got to try. I was never certificated to work on site for JKW eradication but I did witness how poor and slapdash our operatives were so lack of effectiveness was not surprising (similarly I was "clerk of works" on the firm's rebuilding project and saw how poorly insulation details were complied with as BigJ mentioned in another thread) . Workers need to be competent and committed. At the personal level I managed to pull up a clump on our local common 20 years ago and left the arisings to dry out, it appeared to kill the plant out, Woodworks says similar, I'll have to go back and see if it has reappeared. It will never be easy and take a few seasons if it is an established infestation, whatever method is chosen, and yes I would start with glyphosate mid summer onward.

At the olympic park it all soil was excavated and reburied below 4m in plastic lined cells, It was probably not successful because of the scale and poor implementation.

When I worked on a mixed farm we used gramoxone to dessicate prior to combine ? FOE claim 78% of OSR is dessicated with glyphosate and it appears to be cleared for all crops whether food or industrial. FOE quote " For example, the increased use of glyphosate as a desiccant on UK wheat crops has been linked to increased glyphosate residues in UK breadx ."
