  1. Does it rest on that ledge under the flue and slope up toward the front, resting on the little spigot top left of the second picture? I would buy a sheet of 20mm vermiculite board and cut it to fit.
  2. Go to the naughty step Marcus but don't talk to Kevin.
  3. No this is marketed for women I had to raid my Xmas present stash for this shot
  4. Naughty of you but I agree with what you say
  5. Caesium137 and strontium90 are significant sources resulting from uranium235 fission and they emit high energy electrons (beta particles), even those that decay with helium nuclei (alpha particles) are still a danger when the dust is inhaled, then depending on the half life (strontium90 about 25 years) they continue to emit the particles inside you or the sheep and that does the damage.
  6. Yes but in my case I considered it prudent to pay for it in view of my trade being one with amongst the highest accidental death rates.
  7. I know that it is used to inoculate a healthy gut flora/fauna into the intestines of patients who have had an intense course of antibiotics that have killed all bacteria except the resistant ones, like clostridium difficele. Otherwise the resistant ones have a monopoly and destroy the small intestine, causing the patient to starve to death. I saw my father die this way before the problem was recognised 18 years ago.
  8. I wonder if this was dropped as a result of the various mis selling of financial services because it always seemed part of the mortgage deals. It was part of mine and I also had £50k simple life insurance until the youngest was 18. Accident, injury or loss of income had too many get outs apart from being expensive so I did without. My eldest daughter had to bail me out for a few weeks after I crushed my pelvis and femoral nerve.
  9. I used to carry one of those costco 80 quid 2t generators and a 5" grinder for getting wire off of the rotor. Came in handy just after I had signed the MOD RAMS which specified no hot works or 240V tools and they found the locks had been superglued, the range master, Chico, had to give me a special dispensation rather than pay the firm's cost for the day.
  10. Yes the next blip was young american mechanics from sticking oily rags in their pockets.
  11. Back in the days of the last whole earth catalog it was suggested to leave a gap between the run off and the collection so that the first drops of rain washed off the accumulated dust and then as it turned to a torrent the water could jump the gap. I think is is well to be wary of soot after all it is Products of Incomplete Combustion and includes Polycyclic Aromatic Hydrocarbons many of which are known carcinogens. The first recognised industrial disease was testicular cancer found in young chimney sweeps.
  12. The same here, not really needed to light it but after a rainy day it made the evening cosy.
  13. Well yes but Paul is about the only member of the "establishment" willing to answer most questions so no need to frighten him off.
  14. 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.
  15. 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.
  16. Agreed don't put a 5" cowl onto a 6" flue
  17. 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.
  18. 84 I read but it must vary by country.
  19. Pistols or swords and please may I have my glove back
  20. 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.
  21. 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.
  22. 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.
  23. My thoughts too but what ifs won't get us anywhere
  24. 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.
  25. 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
