  1. Well yes but Paul is about the only member of the "establishment" willing to answer most questions so no need to frighten him off.
  2. Except it will mean moving much more lower temperature air, I tried this initially and it didn't warm the other room noticeably. It should work if the duct is well insulated, I guess it would best be incorporated into a Mechanical Whole House Ventilation System but my house is probably not airtight enough for that. My little fan was about 60 quid and ducting is cheap enough as are plastic grills.
  3. Yes mine is a 100W 150mm ventaxia steel centrifugal inline fan with a few speeds, I only use the lowest. This sucks hot air from the convection vents of the morso s11 through two home made aluminium manifolds and 50mm flexible exhaust pipes and through a hole in the wall then vents 30C warm air into the room 3 metres away at floor level. We did not use gas for space heating last year as a result but burned about 8m3 stack of mixed wood.
  4. Agreed don't put a 5" cowl onto a 6" flue
  5. Maybe something has gone bad in the Battery Management System. I have some cheap Aldi cordless stuff and this has happened to one of my batteries. It was easy enough to split the pack and check each cell voltage. As I couldn't find the fault I bought 5 individual chargers off ebay for a fiver and charged each cell separately to 3.6V (only while I was nearby to monitor as I don't trust lithium cells not to burst into flame). Real pain but saves throwing the battery.
  6. 84 I read but it must vary by country.
  7. Pistols or swords and please may I have my glove back
  8. Well unlike stubby I haven't got more than one pair of boots, one pair class A trousers past their best and some orange class C and two out of date hats but people are not asking me to do work now so I only cut logs. Having a blood clot take me by surprise a year ago I guess I am somewhat at risk but growing old always seems accompanied by ailments. I aim to get to the median age of death in 13 years but who knows, I am still relatively fit.
  9. I seldom wear my woodwalkers now, they are pushing 10 years old. I have just checked the joint between the boot and the vibram sole and no sign of cracking yet. Like @Stubby I won't be buying more, indeed I doubt I will buy any ppe replacements.
  10. I had a saw that jammed the starter occasionally and that was because the spool the cord wound on had a split and occasionally two lays of the starter cord would slip side by side on a pull and expand the reel against the case.
  11. My thoughts too but what ifs won't get us anywhere
  12. Yes storage is the big issue and just like insulate britain it has been ignored by governments to get us where we are now. Wind produces more in the winter and today I think it is producing 1/3 of our electricity but I haven't checked if that lasted throughout the day, my panels again produced 100% of my electricity (very good for late October) and I still cannot understand why more support was not given to battery solar systems to act as peak lopping storage. Pumped storage has just about used up all the niches available in Britain and that is only storing for daily peaks and I don't know how much of our daily peak demand would have to be stored. In the short term (5-10 years) just being able to switch off gas generation a while will help but to get us out of fossil fuels is all dreaming at the moment. There is a compressed gas and a liquefied air storage plant somewhere here but to my mind they are best used in conjunction with a gas turbine to get the best out of the storage. My needs are modest, I only need 450kWh in the 5 winter months and could produce it in the summer but where on earth could I keep about 450m^3 of compressed air at 1000PSI. Of course we are still a long way off from utilising all the wind energy we produce now with the grid curtailing production because the national grid has not kept up. My guess is it will need to be as chemical energy imported from a country with a massive solar farm in just the same way we import fossil fuels now. Also fossil fuels have been too cheap and we are going to have to use less, remember it is less than 100 years since most of Britain got electric light. Anyway my comment about nuclear energy was mostly about how the money would be better spent on domestic renewable electricity rather than a rant about it. My rant is about foreign companies who will own and operate it.
  13. It depends on the tree but the cambium feeds the roots and the roots provide sap up the sapwood, so you have started killing the root. Also same species trees can root graft and keep the tree alive. I have pictures of a beech plantation that was being outgrown by self seeded pine trees. I ring barked ones adajacent to the beech but they did not die. They continued to add girth above the cut but not below until eventually they grafted over the cut. been a vandal
  14. It will have been off at both ends, the system has to be kept full of gas at pressure to prevent air getting in. It's the same here and that's why in the event of real trouble with gas supplies they will shut big gas users and power stations. As it is there is a glut of gas coming to Wales with several LNG ships desperate to unload. In the 7 months since the crisis began american and middle eastern countries have been liquefying gas and sending it to Europe, the problem is I think only Spain and Wales have facilities for turning back to gas and piping it, large amounts of gas are being piped across southern britain to europe. In france the state owned EDF is frantically bringing nuclear power stations back online. Ours are coming to end of life and it is very debatable if it is worth pursuing the building of the three French and Chinese ones under construction as this will be over one way or another before they can possibly be commissioned and their electricity will be more expensive that renewables, especially wind and domestic solar PV. Nearly all our storage is in the high pressure pipework.
  15. Recent research sees to suggest a tree grows up with the propagules of various fungi within it, just like we humans have more microbe cells in our bodies than human cells. These propagules then become active rotters when the tree is stressed or dying from an onslaught of spores like we see with chalara. Whether it is these fungi within or just secondary infections you are seeing I don't know but previous experience from windblown beech some 35 years ago suggests there is a significant loss of strength within a couple of years even though the wood looks white still. Mature rees with dieback symptoms may have been repeatedly infected over a number of years since 2012 to give opportunity for secondary infections to take hold. Also I do not know if chalara itself affects the wood.
  16. I was thinking it might go down first now the grub screw is out, dislocate from the top hinge and then lift. Else use more oil and screwdriver under the bottom hinge pin mushroom head I would leave well enough alone and glue the rope in with the door on, maybe with a clamp or two starting at the top.
  17. Generally the heather survives if the cut is above a growing point, a bit like a conifer hedge. The problem is where the material gets dumped, it really needs taking completely off the heath. A chap that used to work for me called it a tin sheep. Here we see bracken invading, worse I suspect due to climate change. I have a theory that, with height set above the heather, cut and collect even the dead standing fronds would gradually remove potassium and favour the heathers again. Of course a high cut in August would benefit most but there tend to be issues with bird nesting, I would still go for it in dense stands of bracken where its alleopathic effect meant it was a monoculture I devised a simple means of turning the arisings to biochar that could then be used off site having a similar effect of removing minerals as common grazing of cattle did in the distant past.
  18. My mother used to feed a red squirrel on the kitchen table in the mid 1920s here but they have been gone all my life, I have only seen them in the lake district.
  19. Is that a cut and collect on heath in the last frame?
  20. Perhaps you should edit your post to mansionette? Got through the last couple of years but a bit battered, I must visit some time when the weather picks up in the spring.
  21. Little cottage, have you moved? Gum tree (eucalyptus)
  22. If it doesn't snap with a shallow gob it will just sit there leaning, or worse, barber chair.
  23. In a mast year they fill out and are viable, I used to eat them but some claimed they were bad for you. Little white nuts. Wrigleys used to sell chewing gum called beech nut but I doubt they had beech nuts in them because mast years were a lot less frequent. This last summer I noticed a few beech cotyledon leaved seedlins in the wood far from any beech trees and wondered what transported them that far, grey squirrels I guess.
  24. I'm a bit challenged when it comes to recognising social situations such that when I first saw "The Office" midway into an episode I couldn't assimilate whether it was reality and I begin to wonder about this.
  25. Yes it looks like it had been fractured before. I guess that is weldable steel hopefully they have access to a line borer, it's doable but probably expensive. Let me know how they manage.
