  1. I think I agree but need to clarify your naming convention. The preset is a tie strap with the rivets already set in it, the loop is closed and a second tie strap is then place over the rivets and the rivet is spun. If the rivet is first forced hard then the new tie strap is fixed securely to the rivet, with the rivet now fully expended into the tie strap hole and the increased friction between the rivet shoulder and tie strap adds strength, it also reduces any play. I wonder if there is play then the one of the tie straps can flex. This flexing could fatigue and snap the tie strap in the middle, the extra stress then straining the weakest part of the remaining tie strap at the rivet??
  2. He hasn't been back this month and may not realise how rude you consider him eh @keptenjim
  3. @bmp01 I can't comment on milling as I didn't do hardly any with a chain but it strikes me cutting down the grain is harsher than across. Which order did the tie straps break? I generally noticed the problem of one side failing before the lot let go. When I did break chains it was almost always at the joining link and I put this down to lack of support as the rivet was spun. Also the factory riveters really thump the rivet as it is spun whereas the manual spinners spread the rivet head without that much pressure, I hope @nepia doesn't come across this problem with my recent efforts.
  4. Are we all on Wellingtonia?
  5. Why so low? I would expect a yield class of 4-8M3/Ha/Yr and it's just over a hectare so in 30 years there could be 120+m3 standing, half of that as thinning.
  6. I was having a problem parsing that, clever and cleaver. The box splitter is marvelous Bill
  7. looks like elm disease has done for it. It may shoot from the stump if cut back
  8. This is why a stove and flue need to be well sealed and I doubt the small extra air supply required by the new regulations can supply sufficient air to generate enough heat to damage anything in the event of a chimney fire. My memory of a chimney fire (apart from the very characteristic smell) is a roaring chimney above an open fire with red sparks and a beautiful blue flame dancing on top of the chimney pot. The blue flame was carbon monoxide, formed as CO2 lower down the chimney was reduced by glowing soot higher up and intense heat as the draw from the super hot chimney was sucking in ample air from the room. Stuffing wet towels to block the chimney calmed it down but the fire service with a bucket of water and a stirrup pump feeding a hose attached to chimney rods put it out. I was 25ish and in the first house (tied cottage) of our own. Of course if you fill a stove with very dry logs and it gets hot enough to carbonise even if you shut the air off you will continue to send unburned wood gas up the chimney and the tarry vapours will condense as their dew point will be well above 100C.
  9. This forum is probably not much good to you if bad spelling is an issue
  10. I don't think that is much different from a covenant in english freeholds, the Duke's estate can prevent certain developments on the land.
  11. Yes but I think you only pay back VAT on the depreciated value of the assets you purchased
  12. Adjustment is by adding plastic spacer washers above the blade. You can dangle them from a rope and swing them for wide steep banks, they also run on chainsaw fuel. Mind I haven't used my two for over 30 years. My granddaughter borrowed one a couple of years back and complained it didn't cope with long grass as well as the little 3.5 hp sovereign with the b&S engine
  13. Yes I think the balloon tanks are liquid feed, this is why the coils are above the flame. Vehicle tanks have a ball valve in them to prevent the tanks filling over 70% because as LPG gets hot it expands and would rupture a tank if no space for vapour so you do need an LPG pump to fill it safely. So the pump has to overcome the back pressure from this valve before it can pass the liquid. Domestic gas supplies are top take off and vapour so no good for filling a vehicle. Of course it is relatively easy to fill it from a 47kg bottle and the safety space is already built into that at the factory that fills them. I have no idea what the bulk price of lpg is now, I did look into it when I converted my LR but the safety requirements meant it was not possible at home as my curtilage is too small. In the late 90s there was a glut of lpg as the result of something that happened during refining for petrol and diesel but as with most things as a nation it was decided we were better not doing refining but let other countries do it for us while we lay back and rested on the financial sectors "hidden" exports to pay for it.
  14. They don't dye lpg so get a bulk supply for your hot air balloon
  15. Something must be holding the needle controlling fuel into the diaphragm chamber open. Either the needle tip is worn or some crap has built up and pushing the diaphragm
  16. 12 years ago my LR 110 V8 did about 14MPG on LPG and 19 on Petrol. It paid me as I seldom traveled more than 40 miles round trip and the servicing costs were a fraction of a 200 or 300tdi for about the same performance. The difference in capital cost was vast which is what made it affordable. Nowadays all but one of the forecourts I used have had the lpg pump removed.
  17. It would be no different; the crown estate is effectively the government now as the royal family gave up any interest in the crown estate in favour of the sovereign grant.
  18. It's much more difficult now and you cannot register the land without the landowner being told and given the opportunity to put up a fight but it could become a negotiating point. It may be worth paying the land registry the few quid to ascertain whether the crown did get proper title, something similar happened to my dad's access drive but the title was passed to a trust before the developer liquidated and he was able to buy the land shared with his neighbour.
  19. I've head of this happening, it's a shame they came back to you with a valuation you cannot afford. If no one else has an interest or likely to dob you inwhy not fence it off and maintain it for the next 20 years, then claim adverse possession?
  20. Did you mean accepting? Apart from not being small or cheap I like the look of the Pug 3008 hybrid4 but it seems to be the only 3008 model that you cannot get a towbar for. Solo they claim up to 30 miles range on battery alone. Most of the summer that would mean running on free electricity for me but for the capital cost.
  21. Works best with lady groundies
  22. Yes no problem if the flue liner stays above the dew point ( which will be somewhat below 100C)
  23. Too far for me to help but it looks like a norway spruce
  24. That doesn't make a lot of sense to me as the turbulence would cause too much mixing as the cold air blew into the warmer air, thus overall diluting the heat. Assuming the air stratifies as hot at the ceiling of the upper room then logically suck air at ceiling level and pipe it to floor level downstairs but as I said this leads to moving a lot more barely warm air than if you take a smaller amount of hotter air directly from the stove and pipe it down. Also something I was unable to arrange was to vent the hot air out of a slot horizontally at floor level, the theory being the Coanda effect should let the hotter air hug the floor further before it rises.
  25. I do something similar from one downstairs room to te next. I found using a duct to take air from the warm room to the other wasn't effective as you needed to shift a lot of air with very little temperature difference. So I made a couple of flexible metal ducts and sucked hotter air (about 30-40C directly above the stove convection vents and blew it to the room next door, my major mistake was not insulating the ducts but it works and as a result we did not use the central heating at all last year. Downside is we got through a 5m3 stack of mixed logs. The fan noise is a bit intrusive and consumes about 50W on its lowest setting, I need to measure this somewhen.
