I don't know, honey fungus gets everywhere, standard advice was to not plant a susceptible species near the site of the infected tree. Also the RHS stance seemed to be from personal experience of their curator rather than science. After 1987 we had to pick up or excavate all the stumps and transport them to a stump dump. Awkward to get at, not windblown ones, were blasted.

It's not really secondary air, it's a way of getting hot excess air in to (nearly) guarantee a burn out. Looking at the video earlier in the thread comparing stoves this extra excess air ( there is always some excess, unused oxygen in the secondary air) being introduced probably increases massflow significantly, so heat is lost in this air being given a free ride and exiting at whatever temperature is left after heat exchanges to the room. One benefit of the catalyst is that you can feed it nearer stoichiometric amounts of air thus minimising massflow but I', still not convinced of the cost benefit.

With those failed unions near the base already it's plainly compromised, as the name says it's not a strong timber and it has an evolutionary trait to vegetatively propagate by layering after cracking and reaching the ground.

Yes hornbeam coppices well but often older maidens fail to resprout.

Yes and it does so from the base, so over time the stump rots out and the coppice grows as a ring around it.

Quite logical progression; a catalytic converter allegedly enables a clean burn of a smouldering log, i.e. no proper flame or secondary secondary combustion but a clean burn. Add a heat exchanger to the flue and you further cool the flue, this is what condensing gas boilers do, they have a drain. I see it less now, maybe because of ss liners but one could often trace out the course of a flue up a brick chimney by brown staining of the mortar as the sooty condensation percolated through. It was also acidic so gradually leached out the lime in the mortar.

No but even with 20%mc wood you're chucking a fair amount of water up the flue so ideally want it to exit the top above the dew point. Every kilo of wood you burn at 20%mc means you're chucking 0.6 litres of water up there. I haven't worked out the saturation of the mixture of water, nitrogen, oxygen and carbon dioxide as there are a number of variables so safest to keep it above 100C

Mine are a bit more bashed than that web picture, I have one straight and one bent tip pair. I guess fishing out rubber hoses has been their main use.

Hemostats, because they lock shut, useful addition to the toolkit

Yes it was early days for the concept and the owner just expected too much from it, he had the space to increase the ground loop but they simply gave up on it.

His explanations did not make sense to me

I cannot understand the need for a catalytic converter on a stove. I understand it on petrol engines where you only have milliseconds to complete the burn and it has to be near enough stoichiometric but on a stove you have a retention time of seconds and massively increased excess air. Even so a catalyst is unlikely to work on those graphitised bits of soot as they are highly recalcitrant. Think of the requirement for burning being an energy wall which you have to lift the constituents up to until the can burn and fall off the other side, a catalyst is just like a lower section of wall so the constituents don'r have to reach as high before they burn. To my mind an electrostatic precipitator would be more sense but until they are mass produced and come down to less than £100 there'll be little uptake. Where to fit one in my set up is the problem. I can only see the chimney top as being viable and that would mean accessing it to service it.

I've told the story before of the big country house that installed GSHP heating and used the heat for the house, offices, pool and stables (posh horses). The loop was extensive and on a cold day you could trace out the pipe in the lawn because the antifreeze mix in the pipes had cooled the ground so much it had frozen and the heave was visible. This must be over 30 years ago now.

This sounds similar to the kunzel installation we did for an chap that runs an oak framing company except he had a concrete slab and under floor heating. I think the Kunzel (now out of business) was based on the original Baxi gasification idea (sold as Tarn in US). It burned once per day and used hot air (with a graphite resistance heater) to ignite the logs directly, there was a 3tonne water heat store as the heat store cooled it triggered the burn. The firm also put in a Kob gasifier boiler at an institution near Petersfield, it ran the old radiators in the large property, was manually triggered and burned cord wood. Both only needed only annual maintenance and cleaning unlike the various chip stokers we installed which needed frequent attention.

That looks like bacterial, rowan are susceptible to fireblight.

Yeah, maybe crack willow and we know how they propagate

Prove it

Think of the song "oh Danny boy"

Interesting synchronicity, the current policing bill going through parliament is ambiguously worded, ostensibly it's to allow the police to deal with illegal travellers' parking up but the interpretation could be far more wide ranging. Trespass has been a civil offence for a long time and I think this act will make much innocent trespassing a criminal offence, such as detouring around an obstruction on a right of way or unblocking a footpath.

I prefer the place over the road

Me too, didn't she have a problem a little while back?

I dug one of mine out, I remember my dad buying it in the early 60s, a Spear and Jackson 8 or 9" when new, a bit shorter now. It tapers 1 in 6 which is about 9 degrees and yes it was not at all unusual to bury them and only lift an inch then stick two more in stacked and a slight angle to each other and tap them in, free the original up and move it a bit closer to the hinge and keep banging, Any greater angle and they would have bounced out.

Yea but tipping over a big oak that needs 3 or more wedges steel gets the job done. I'm surprised at that 1" in 4" measure, that's about 30 degrees and I would have thought less than half that. I'll dig one of mine out. PS I just looked at that again and it is around 14 degrees and not 30 so about what I was thinking. The main thing about steel wedges is they must be softer than the hammer you use to knock them in, this means over time they mushroom and need cleaning up, oxy-acetylene is favourite else a cutting disk in angle grinder. The reason is to avoid shards pinging off when knocking them in hard, they are known to take eyes out.

My guess is the later transits have a CANBUS system which controls the lights, these need a converter wired in to the trailer socket to work trailer boards. So I would think that error code does relate to the trailer lighting circuit. Did it work before or is it the first use?

The coppice bloke I knew would leave a sunshoot and step on the joint with the main stool to split it away at ground level, he would peg this. I never got the opportunity to return to the site and see if the layer had taken. Yes this is what I was told, their taste is more catholic than native beasts. This is probably a reason why dormice are in trouble as they will only take ripe nuts.
