  1. Yes I saw that but I had also seen a guy with a similar branch logger hold a pole back to stop it feeding, you couldn't do this with a two roller feed so I surmised it would not handle widely spreading branchwood.
  2. The reason for retaining ash trees seems to be in order to establish some sort of resistant genetic strains, I would say if you can see it's chalara (as opposed to other)induced dieback then there's no resistance worth keeping As ash is relatively perishable it's best cropped soonest. Deterioration of ash has been mentioned in threads today by GaryP and @Alycidon
  3. Beau I had the impression that these branch loggers would not pull difficult material through as a roller feed would, what's your experience? Having had a few bags of logged slabwood from Willsmills one I would be happy to only burn this and as you have found it's ideal for charcoal making, even more so if the fines can be profitably sold. What's needed is a simple separating method to skim off the logwood. I'm very wary overall of whole tree harvesting because of its effect on Soil Organic Carbon.
  4. I totally agree and this of course is the tragedy of other nations not being able to afford or manage their affairs as we do and it's not as if we couldn't do much better. One of my worries about cash crops from third world economy is the gradual removal of minerals necessary for good husbandry over time as I get the impression artificial fertilisers are not affordable. It;s yet another reason I support the application of biochar paid for by carbon credits from the wealthy nations, It means the cash crop stays on site yet the farmer still gets a cash income. I eat a reduced meat diet and even that aggressive kernowman seems to agree farming would be a bit better if food that people could eat would best not be fed to animals and that animals were best foraging for their food on land that is not accessible for cultivation. I like it but am not knowledgeable enough to comment on the practicability
  5. This is a good example of how innovations are readily adopted without taking into account external costs, sometimes the effects are not seen for decades, like asbestosis for instance as well as halogenated hydrocarbons released into the atmosphere and more generally increases in atmospheric CO2. I think there are two different levels here, first is microplastics which are an inevitable result of wear and tear, like fibrils from plastic threads in clothing, which easily enter living organisms and the other is discarded plastic, like litter, flotsam and jetsam and plastics deliberately discharged into the sea from domestic and industrial waste. This latter may well be from plastics we have exported as baled waste to other countries for disposal, IMO waste should be dealt with locally and export was never a good option. Most people don't discard their rubbish other than in a proper disposal system, so the conspicuous litter in the countryside is a result of a small proportion of us, the micro particles, from wear and tear , like bits of strimmer cord or washing machine outlets is likely attributable to all of us.
  6. Air freight is yet another worry, it is relatively cheap because we can cannot get a global agreement on it's relatively high cost to the environment so it's fuel remains untaxed. Hence often making it cheaper than local sources. I imagine this has caused a lot of the decline in growing things under glass in UK.
  7. If it is a business workshop I believ you must have it licensed by the LA.
  8. The blacksmith's cum welding shop I worked in during college was heated by a Salamander burning waste oil, it was only supposed to burn diesel, I definitely wouldn't want to use a flueless device nowadays. https://en.wikipedia.org/wiki/Smudge_pot
  9. Which is not an unreasonable time for a busy firm to schedule work. Why not just buy the seals and do it yourself as you say it's an easy job. I did mine on several occasions.
  10. I'm not so sure about advocating this, I was more making the point that dirty plastic was better burned in a dedicated power station (not an incinerator taking all residual rubbish ) rather than exported or lnd filled.
  11. Hydraulic and Engineering Services Ltd Unit 5, 6 & 7 Victory Park Trident Close Medway City Estate Strood Kent ME2 4ER They made a replacement for the main lift ram on my FMV290 in 2012 for about 500 quid
  12. Yes he's given me good service on several occasions
  13. Why? If we are talking about a municipal incineration plant it will have high temperatures to make sure everything burns cleanly and filters/scrubbers on the exhaust to pick up heavy metals and and such. Most plastics are simple, even PVC when burned properly only gives off H2O, CO2 and HCL. It is however difficult to burn in a simple device because the flame is too short for a clean burnout so PICs including dioxins are given off. You can tell if its burning cleanly because a cloud forms abouve the exhaust, this is because the HCl gas given off is so hydrophylic it grabs any moisture out of the air and condences as hydrochlric acid. An incineration plant will absorb this before it is released IF it is run well (most are not). Whilst I think it would be great to recycle plastics to make bottles and containers again this does not seem practical and we have made a mess of collecting and separating them. As we still burn oil for electricity and plastics are essentially just polymers (long chains) of CH2 as are most mineral oils and they only account for a very small portion of oil products consumed then why not use them for heat?
  14. That was a while back then, last I heard it was to triple rinse into the sprayer and then dispose as normal commercial waste. Mind not many do it even though it is sensible and practicable.
  15. I only rode as a youngster I stopped commuting by bike around 1976 and that was a purely practical one, D14/4. Changed the main bearings after work on the kitchen table and back to work on it the next day. I never have been on a racing track. Much the same after I had a mishap on the tractor, lost so much trade that business never did pick up again, struggled on for 10 years then got a management job. I made a mistake about the Matchless, it was a G2 250 I was on the back, I was confusing it with the BSA C15 another mate had, I thought both of them were tame compared with my 250 Enfield. Yes I would have loved a AJS 7R or Mathless G50 but the Manx Norton was the pinnacle of 1940s design, much in common with the merlin engine, less supercharger. I loved the looks of the DBD34 and Velocette Venom but they were the epitomy of post war management not willing to re invest profits into machinery and research which was prevalent as Britain struggled to recover from demands from the US.
  16. That's bad, how did you manage to work again? Did you ride again?
  17. Me too but I was a bit more flexible when I was 16 so when I went over the top I didn't sustain damage. Matchbox G15 wasn't so lucky.
  18. He was lucky compared with the chap who hauled some of our timber, jumped off the loader and left his ring and finger on the controls.
  19. One of the properties of OSR is that it clings to metal so doen't need an additive.
  20. It seems to have been triggered by an older gent allegedly pulling onto the wrong carriageway of the A3, the local news posted a picture but I couldn't recognise the spot. Anyway the gent could only reada plate at 7 metres. I have always worn specs, initially for driving but soon after permanently since I was 16. Nowadays as my sight has changed I can manage the 20 metres with one eye but not the other but am so accustomed to wearing glasses that I continue to.
  21. We used these to level logs for the lucas mill, we just cut a shallow step in the log first. It was a simple 50 quid jackall. You can control the sideways movement to some extent by holding the top. As we were only lifting to place chocks under there wasn't very far it could go.
  22. There'll be an opportunity cost calculation to make, if the alternate market pays more for a standing tree then why try and sell firewood? Back in the day I used to have gleanings from the tops after sawlogs had been extracted for free on those estates that wanted the site tidied . Others, especially shooting estates would have the felling company pile and burn it with a Cat 751 and powerfork as they wanted the site clear quickly. Now I walk through our local woodlands after a harvester has been through and see easily enough branchwood to get firewood from. I see plenty of small woodlands, particularly woodland trust properties where trees are cut to waste and stacked as ecopiles. These are often woods that I worked for pulpwood and it was only the crashing of the roadside price by large scale harvesting that meant owners shut the gate. If firewood is truly rising in price then there will be the opportunity to offer these owners a standing price again even though the fell and extract price will be much more than a large scale harvesting operation. Talking to a chap I used to work with; he said his outfit cannot afford to do sites less than 1500m3 as the cost of low loading a harvester and forwarder became too significant, often they bring in a 360 for a few days to reinstate ( i.e. scrape over the damage to leave a superficially clear site). It should still make sense to harvest the smaller sites by reverting to winter felling and summer extraction with a tractor-trailer-grapple and 40kph gearbox and transport ~9m3 direct from stump to yard on a 10 mile radius. I say this as I would no longer risk leaving a tractor on site so if it has to come home it may as well carry a load.
  23. What happened do you miss the flight?
