  1. It was all we had in the 70s but by mid 80s I came across army abseil rope, I'd never thought about SRT until reading here.
  2. Who are the "them " you refer to? We have had a solution proposed, which I have followed and supported for the last two decades. It doesn't fit in with current economic systems, actioning and verifying it is possibly beyond the ken of governments. Carbon exists in the ground as fossil fuels and rocks. there are estimated to be 16000 billion tonnes there or under the deep ocean. It all derived from living organisms. This is all in a long term geological cycle unless we dig it up and release the carbon as a fuel or to make cement. Similarly there are rocks formed from volcanic activity and buried which will absorb CO2 if they are exposed to weathering. Geoengineering solutions want to go down the path of mining, crushing and scattering such CO2 absorbers, I consider that a dangerous route. Currently terrestrial photosynthetic activity cycles about 120 billion tonnes annually by fixing carbohydrates during photosynthesis and releasing about the same as it dies and rots. The oceans similarly cycle about 90 billion tonnes annually. As humans started managing their environment thousands of years ago they cleared land for agriculture, this reduced the above ground biomass carbon content but as we know the increased release of carbon really took off 200 years ago. When I was at school we learned that as CO2 in the atmosphere increased it favoured plants which stored had superior ability to utilise sunlight. These should have had the ability to keep more carbon as living biomass, and they do for over half of the carbon we are setting free. However currently fossil fuels are releasing 9 billion tonnes back into the atmosphere of which plan and marine life is only managing to buffer 5 billion tonnes over and above the 210 billion tonnes of their exchanges with the atmosphere and oceans, plus as 45% of the carbon in the surface cycle at any moment is in an equilibrium between surface ocean and atmosphere marine activity that would form chalky sediments is reduced as CO2 in solution tends to make the ocean less alkaline. To my mind intercepting some of the 60 billion tonnes that would rot and decay back to CO2 and water and making it recalcitrant and burying it could be done anywhere on the planet where crops are grown or timber harvested. At the turn of the millennium an even more elderly friend of mine hoped before he died he would witness the first billion tonnes of carbon returned to the soil in this way, it isn't happening or likely.
  3. I'd take issue with that too as one of the reasons healthy ash will barber chair is the high strength of the hinge
  4. They'll be around 3A, what is the granberg motor drawing? A power supply from a gaming PC will be up to 20A at 12V Many car battery chargers will only start if they see a battery so you would need a small gel six cell in the circuit.
  5. That'll be why they made axe handles from it then ? I felled some large affected ash last week, 60% crown dead, and there were definite signs of something strange in the basal cross section. Whether it was a secondary infection or signs of the chalara infecting the whole sapwood band I'm unsure. The hinge was still as normal.
  6. Sounds strange, after we felled trees, and treated stumps, on a steep chalky embankment we had to go back and pull the stumps out as they came loose several years later. Remember when the railway was built there were no trees and kept that way by the deveg gangs.
  7. How about the switched mode power supply from a desktop computer?
  8. The sale of goods act was replaced by the consumer rights act in 2015 but I think you are generally right. If it is an individual to individual sale there is little comeback unless the seller has lied about the condition. If it is a business to consumer sale there are a number of protections if the goods are not as described, have a fault or plain don't work under the above act If it's a business to business sale then there is far less protection but what's offered must be as described and there would be a comeback through the courts if a fault the dealer knew about but hadn't mentioned became apparent.
  9. 1kg needs a force of 9.81Newtons to lift it. so I tonne requires 9.81kN to lift it. If the kingpost of the loader is 1 metre away from the load you will need a torque of 9.81kN-m to lift the load So 160kN-m will clean lift 8.15 tonnes 2 metres from the kingpost. That's a helluva lift, my county will do 2 after you allow for the grapple and rotator as generally you cannot get closer because of the shape of the envelope. Having said that I once loaded 120Hft (about 4tonnes) onto the trailer with a 24'6" log,
  10. Not only embarrassing, I wouldn't want my kids breathing in the smoke from that foam
  11. It would be interesting to weigh a few logs that you load from now and mark their weight, then when you take them out you can see what the water weight loss was. From my experiments I do not see much rate of drying after October, maybe 20% of what you will get in May. To The OP it may be possible to slightly raise the roof at the back to get airflow.
  12. That's naughty putting words into my post. I wouldn't say such things about a virtual marra
  13. They're just for show, Stubby's retired ?
  14. Yes my 4kVA welding genset will only start my 2hp compressor if the air reservoir is empty. Do the engine run air brake compressors put out enough air?
  15. The loader mount doesn't look too clever with so much mass behind the back axle. I was asking £7500 for mine with Moheda 9 tonne trailer but the only buyer wanted to haggle so I kept it. I've nearly repaired the loader on my 1124 which has the pukka Highland bear cab and 4510 loader, once that is done I may sell the 1164 and loader.
  16. Pretty much spot on with those points. On good ground with a long extraction I would fill a couple of artic flat trailers a day where a purpose built forwarder would struggle with the distance. Poor ground and high stumps were a different matter. The big advantage was not having low loader costs between sites which meant small jobs were economic. I'd be interested in what money was being asked for the one posted, it looks like it has been tarted up for sale.
  17. Are those 12 x 38 tyres? If so they will be overloaded with the grapple loader even at their maximum pressure unless they have an unusual ply rating. 14 x 34 would be alright.
  18. Preferably not
  19. I found my tape repair stuff and there was an unused tape refill as well as a working Stihl and Lufkin tape plus the rivets were spilled in the bottom of the drawer. I'd be happy to loan it out if anyone wanted to try their luck at a repair
  20. we used to break quite a few so when a local chainsaw dealer closed about 25 years ago I bought their tape riveter and a number of plastic tape ends and rivets. I still have it somewhere.
  21. Fairy nuff and it's your old stomping ground
  22. I agreed with all you said up till this point. A full arb report will cost in the same ball park as a fell and remove to ground level and is a luxury I'd reserve for trees with great amenity value. This one has structural problems, the roots are damaging the sidewalk and wall plus it is a tall vigorous tree that is getting too large for a small front garden. Plus it is a turkey oak ?
  23. A day's abstention was always good enough for me for my network rail related urine test, never did a blood one. If it's for liver function I'd say not likely as a lady friend had to be off alcohol for a month to pass that. Too late to worry now.
  24. My guess is spindleshank
  25. When my kids were little I stuck luminous stars and planets on the ceiling, if it was a dull day I would use a remote thyristor flash from a 35mm camera to charge them instantly
