  1. What I should have mentioned is that I would not have been living the last 15 years had I been lone person working because of a freak, but avoidable, mishap.
  2. I gave up with FC completely when they objected to my tractors not being CE marked around 95. Prior to that I did a bit of extraction for a harvesting company. I had negotiated thinnings directly with the beat forester but then they appointed a harvesting man to sell all their smaller parcels of timber, last I heard he had not covered his wages, let alone oncost, with the gross value of sales but this was 25 years ago. In the small broadleaved woods we were working as you say the payment had become just a token, when I started I paid 30% of the roadside price for hardwood thinnings. I suppose you know Jonathan Howe near Andover? He was always very helpful to me.
  3. Because you have created a circulation loop, whilst the vast majority of the flue gases will go upward if one stove is cooler and in a cooler part of the house than the other a thermosyphon will develop, hot gas will rise to the junction be cooled and then descend into the colder place. I imagine fluctating wind could exacerbate this. I was once called out to a recent AGA installation which tested OK with smoke matches but would not start drawing in the requisite time. I had been asked to fell all the adjacent trees, on the Aga installer's suggestion. I declined the job and explained the what I thought was the reason for the problem. It was a large high ceilinged 2 storey house with a single storey annexe for the kitchen. Largely open plan, recently renovated and gas centrally heated. The chimney in the main room rose through the two storeys and exited above the high pitched ridge. The flue for the Aga used a similar brick chimney but exiting the single storey roof some 3 metres lower. The aga had been intalled without a dedicated air supply to make it room sealed and the house was no longer draughty, with new doors and double glazing. So a mixture of the hot house evacuating air up the taller chimney and a thermally massive chimney to get warm enough to draw combined to stop the aga getting enough air. I had worked in the grounds and delivered logs to the previous owners for about 20 years, I never heard from the new owners again. I still haven't checked if it is possible to install Agas room sealed. The thing about building regs for solid fueled devices is they have to take into account the variability of fuel, modern gas or oil heaters simply won't work unless fed a fuel they are designed for but people bung all manner of rubbish in stoves and open fires and it is important to vent the combustion products well up and away from air the occupants breathe.
  4. I agree, separate flues, but it's not that they won't draw it's that one may leak into the other (probably upper) fireplace especially once the flames have died down and there is just char gently producing a mixture of carbon dioxide and carbon monoxide. I once calculated the diffusion of a gas molecule in still air and it is surprisingly fast as they collide with each other every 10,000th of a mm traveled.
  5. By the Woodman where the tram used to run? Long way from Pembroke. I lived in Bishopston for a couple of years in the days before the common was fenced.
  6. There's an open grown oak that has failed this way and the two tops have then fallen away from the butt, it's in a field adjacent to a dual carriageway where there are roadworks, A23 Handcross Hill going south, and I have been unable to stop and have a look at it the few times I have been traveling to Brighton.
  7. The split never heals, the best that could happen would be the callus growth gradually merges to start a complete new ring after several years, this callus growth will be "better" wood than the original (denser, less vessels) but it would still contain the split wood, and any infections, inside it. I know very little of bracing, I last practiced it, job specced by boss, in about 1976, it would never pay unless a specimen tree or a high value target and in this case the wood/shelterbelt needs thinning. Over the years I have come across an occassional tree with dangling wires from a failed brace where the supported structure is still intact
  8. Have a look at this one, the callus looks at least 3 seasons, wood peckers have been having a go so I suspect a summer bat roost. splitoak | Flickr - Photo Sharing! It's a surprising one as the tree is in a wood of self sown oaks, average 50 years old and vigorous, on a steep bank. The lever arm isn't that long, about 10 metres and the split is 5 metres up, so 15 metres overall. I cannot decide if it's the tougher densered whorled growth at the two branch unions below that has prevented the crack from propagating. Because the target occupancy is high I think it will have to go. I'm particularly interested in comparing these fork failures with similar failures at the stool of coppice growth because logically a branch union should be stronger than the union between two copice stems merging at the base, they have little opportunity to grow tension wood to resist a tear out.
  9. I agree, maybe a case for a separate machine with hydratongs to pull them through after the grapple loads them.
  10. Brilliant, they don't do directional felling then. Alder? This reminds me of when I did some set dressing for a logging camp film scene. It was in an SSSI so only one tree could be felled on camera, the stumps were imported corsican pine sawlogs and short lengths dressed like your beaver cut and augered into the ground as stumps, I hydratonged the logs in position at "stump". I tried to point out to the director that the trees were supposed to be axe felled and would have concave, not convex, surface and the one to be axe felled would look different, he was unconcerned and one of the gaffers explained they wouldn't notice it in the 1/9d seats. BTW the picture reminds me of a rhyme my mother used to chant when my sister misbehaved: There was a little girl who had a little curl right in the middle of her forrid When she was good she was very very good when she was bad she was h......
  11. Maybeso but they're a disaster for poor finish, harsh on machinery and inept at basic maintenance, at least the ones I deal with. Back to boots, I still keep a couple of pairs of Eltens for comfort but they lack a steel midsole. I will always prefer a boot with protective midsole over the Eltens unless working in the country whether using a chainsaw or not. I saw lots of mishaps with cut legs before protective trouser became available and would not use a chainsaw without them or a helmet with muffs and visor. I did cut my finger with a saw after 30 years when not paying attention but still find it difficult to wear gloves. I would dearly like to find a walking boot that supports arthritic ankles and don't aggravate plantar fasciitus.
  12. +2 mill slots in the base and use Tee section angle iron bolted to concrete or a 6mm plate embedded in slot and concrete.
  13. A bit late to the thread but I bought a ryobi 4 stroke with strimmer, pole saw and a hedge trimmer I think it was 80 quid plus 40 for the chainsaw bit. It's adequate for all the jobs, I have hardly used it as it was specifically bought to lend out instead of my own kit but it has cleared a small garden in Wellingborough that was a couple of metres high with brambles, so it has served its purpose. I used the strimmer today and that was ok for the lawn edges.
  14. This bit is interesting to me because it defineitly says permitted weight, which means once I put a 750kg chipper behind the 7.5 tonne lorry I must use the tacho graph as my license allows me a combination weight of 8.25 tonnes, perversely I can never achieve this as the nose weight of the chipper always counts on the gross weight of the lorry as well as the gross weight of chipper. I had interpreted this the same way as crazy cutter, the exemption still applies for driving to a job with tools, there remains the big grey area as to whether hauling arb arisings from the site fall within "material or equipment for the drivers' use in the course of his work". My strict interpretation was it does not but the nice VOSA lady said she wouldn't be picky. What doesn't seem to have been said is the exemption is for keeping a record of drivers' hours but the time limits do still apply.
  15. I rate Fuelwood products, have never owned any, but may be biased as I know Richard from 30 years back. Having just had a day assisting section felling a wych elm of coppice origin and previously worked at a tree station I don't think any one machine will do the job. The climber basically chogs off the biggest section he can handle so you have 150mm diameter stuff of 700mm long down to 400mm chogs 150 mm long. Smaller stuff going through the chipper. Also many larger chogs arrive with a "handle" from a small side branch. Even my co ground worker couldn't be persuaded to trim them and make them more uniform, the core business is to get in, finish and get out. I would normally have to worry about converting the log wood later but in this instance it was a large site so I got security to announce the availability of logs, all disappeared by 16:30. Which was a relief for me as I took the opportunity to roll over the weighbrige on the way home and grossed 7290kg with chip alone, so about 1640kg of chip after allowing for tare, chipper, kit and men. I'm guessing there would have been the same amount, or more, of logwood. Has anyone recorded the ratio of chip to logs coming into the yard?
  16. How come? I thought under the new regime this was covered in D6 and D7 and cannot see a way around these unless in a domestic garden with the householder doing the burning. I can no longer find the additional restriction on not burning at a higher rate than 1 tonne/hour, which was the one that made air curtain devices difficult to comply. Mind we had no problem with them either despite the EA man saying it couldn't legally be done, mainly because it was clean and no one complained.
  17. Yes but you are both giving the example of small traders with limited labour, what entrepreneurial economics has shown us is that if you can manage labour "pile it high and sell it cheap" produces greater profit, albeit at greater cost . Amen to that, I just about manage to chop my own few tonne, back when I was young and able I'd chop a cord on Saturday and deliver one load on the way home and the next the following day.
  18. +1 reaction growth but beware of what is causing it.
  19. It comes down to nuisance, clean air act, local byelaws and whether you are emitting dark smoke. If you don't contravene any of the above then you may burn up to 10 tonnes of plant material produced on the site ( but not imported from another place) on an open fire, but not in a technical device, in a 24 hour period. You will need an exemption to do it. I have yet to hear of anyone being stopped from burning arb arisings from sites.
  20. Pets are for life and my budgie died in 1967
  21. Mick we all know it's unnacceptible for a dog to challenge it's master but predator made a general observation about my whole post, not the specific point you picked on, you were wrong in this because he is no problem with his food bowl, I was referring to taking a bone from him outside, which is similarly unacceptible. He needs more work than a young girl can give him but I have never understood the workings of a female mind which is why I have become the compleat misogynist. I would not have advised a girl about to start college to have a new dog at all let alone one from a large breed.
  22. I was giving my experience to Pete. Agreed about the training but he's not my dog, I see him at weekends and there's a limit to what I can do. He responds to me better than most but considers me from another pack. I expect him to defend his territory. Running off is unnacceptable and has not changed with the snip but he does eventually return and has never got out of sight. He's a great character and as enjoyable to walk with as my two dogs were.
  23. My granddaughter's 9 month old dalmatian cross was done last month. He will still run off to play with children,bikes,horses and apparently small wooly things in a non agressive way. He bolts after squirrels, foxes and cats. He humped his mum yesterday! I have noticed no difference but have yet to try to take a bone from him, previously he would bare teeth and threaten.
  24. Way back in the days of flower power a mate was studying shellfish in the Tawe estuary for a degree. This river collected run off from all the mines up the valley that had been sources for lead, tin zinc etc. He reckoned that the shells were within an order of magnitude of being smelted to recover the heavy metals.
