  1. Hemostats, because they lock shut, useful addition to the toolkit
  2. 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.
  3. His explanations did not make sense to me
  4. 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.
  5. 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.
  6. 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.
  7. That looks like bacterial, rowan are susceptible to fireblight.
  8. Yeah, maybe crack willow and we know how they propagate
  9. Think of the song "oh Danny boy"
  10. 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. Open letter to the Home Secretary and Secretary of State for Justice FRIENDSOFTHEEARTH.UK Read the open letter calling for the Home Secretary and Secretary of State for Justice to urge the government to... I admit being a bit sceptical about whether travellers should have freedom to litter the countryside but...
  11. Me too, didn't she have a problem a little while back?
  12. 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.
  13. 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.
  14. 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?
  15. 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.
  16. The term for the area of coppice felled, similarly cant.
  17. The poison we used for a pest had seven consecutive consonants at the beginning and nine at the end
  18. I don't use this for distance but do use this method to look at the back of the sink and then get a better idea of where the tree should fall. I hold a stick at arms length between thumb and forefinger so the stick just ouches my cheek, then line it up with top and bottom of the tree and that's where the top should land.
  19. It makes sense but I wonder what the long term effect will be. Hazel coppice became dominant fairly late on and the 7ish year cycle actually seems to fit well with the rotation end maximising mean annual increment. It also gave the size of stems that were needed for traditional stuff, like wattle, hurdles, thatching spars etc. but more importantly for crate making as exports of crockery took off and stoked the industrial revolution. Given that forest cover was very low by then it had the effect of re creating forest glades every 7 years as well as denuding surface fertility. This allowed the gap living species, like bluebells, to flower and seed in light conditions before the canopy overshadowed them again, the lesser surface fertility reduced competition for them from grasses. Having economic value they were protected from grazing animals.
  20. Give? Have you not heard of Lehi? An american backed terrorist group.
  21. I sharpen the front face with 2 to 3 strokes and then after all done one stroke on that top relief. Never as good as new but still good, it's therapeutic and I'm tight.
