  1. If we call that 3m x 2m x1m that gives 6m^3 of space, filled carefully with 70% solid wood and 30% air space allows 4.2m^3 f solid wood. Green pine is about 1m^3 per tonne so potentially 4.2 tonnes of wood.
  2. Old TVO tractor, any Military vehicle with the K60 engine in. It will also be fine in a diesel engine with a conventional pump if you dilute it so as the petrol doesn’t exceed 5-10%. You need to treat it as inflammable as petrol all the time as a spark will set the vapour off.
  3. Not removing the teeth must be a big benefit. I found the stock removal was faster with a diamond disc but never really worked out if there was a cost benefit over the green grit. I always used the green grit outside.
  4. One reason for the diffs being locked in low ratio is to limit the torque any one half shaft has to handle if the other side loses grip. It's often the shock of the spinning wheel stopping that does the damage.
  5. I think those conditions are to stop you publishing something for selling on, like your own A-Z.
  6. I would have thought he'd choose a bike engine! I'm a diesel fan, I like them for their frugality, longevity and luggability, having sat a few feet away from the exhaust of an open cabbed tractor for many years I don't yet know if it has caused me damage. I do concede that particulates are a problem but less convinced about NOx for this climate. Anyway, if the SI engine can last as well, what is the cost of the change? The SI engine is lighter and uses how much more fuel? The issue most likey to cause expense is leaving it at high idle as you fetch more branches but this could be mitigated by auto stop and start on demand or better still going for cyclic hit and miss like Daimler Benz were investigating for their bigger engines, it might sound strange but it gets around one of the problems with a lightly loaded SI engine which is poor volumetric efficiency. The other thing is running it on LPG, this gets around the tax issue somewhat but adds a weight problem. However a dedicated LPG engine will run a higher compression and this is directly related to extra power and efficiency. Yes I still love the sound after having them in various landrover products, still got a range rover engine with weber in garage looking for a home.
  7. Gary I did the same as Paul Melarange but used emapsite. You only get to buy a year's licence but any paper maps you produce can be archived. A licence to print OS maps can also be bought but I've never investigated this. As long as the map you produce acknowledges the OS copyright the licence does allow most things, the only issue I see is if the digital mapping is used at more than one workstation. Amongst other things a licence allows for: " a report to be submitted to a regulatory body to which the Customer is subject in order to meet that regulatory body’s requirements; and/or to include a map within any professional services provided by the Customer to its clients, such map only to be used (in the case of a business client) for the internal administration and operation of such client’s business." Which bit of the licence can you not comply with?
  8. That'll be a pinzgauer you want. Steyhr Puch did the running gear on the G Wagen and the Fiat panda 4wd I think.
  9. Chances are the piston wasn't quite far enough up the bore and the string went in the exhaust port and jammed as the piston came up, whip the exhaust off first and see if you can fish it out. Otherwise the cylinder will have to come off.
  10. I use a 40+ year old Jotul but it's needed some patching up. It's nominally 5kW and would cost about £600 to replace, a Bosch-Worcester combi costs about £700 for 25kW and I've seen some going on for 20 years now. It's largely irrelevant as it's a lifestyle thing, I've always burned logs because I had the raw material available, so apart from effort it is free. Those that buy logs will similarly be considering the lifestyle but without the effort. I regularly offer my neighbours free arb arisings but generally it's too much work. One chap who has lived next door for over 20 years and is a good friendly neighbour took delivery of some hardwood logs yesterday. The logs were barn dried and looked clean and free from stains or mould and occupied half of a Mercedes 3.5 tonne tipper, so a bay 2m x 1.8m x 30cm = bulk 1m^3. It was a well presented luxury good and I'm sure the neighbour wasn't very concerned with calorific value. I didn't ask the log merchant, who I used to supply with all his roundwood 30 years ago, how much he charged but his business is doing well and he was delivering from 10 miles away.
  11. Agreed anything that needs muscle power is too slow for most situations. I demonstrated the flip flop winch as an emergency aid using two broomsticks and a length of starter cord in the yard, never knew if anyone actually made use of it, I only used it to take down hung up trees.
  12. I doubt it shipping in bulk is very energy efficient, have you a cite to show the energy cost incurred in transport from US to Drax? We once did a costing on hauling wood, for energy, from Surrey to Didcot, it worked out less costly than sending electricity the same distance.
  13. What he said but I just used the fluid that came with the sealey kit, tell me more about the more sensitive stuff. On a 2009 ranger we replaced a head at 120k miles and it went again at 230k so it was sold on for export.
  14. I pay about 4p/kWh for gas and don't have a condensing boiler, so lose about 6% of what a better boiler would recoup. BigJ here just posted oil at 37p/litre which beats my gas price by about 0.5pkWh In recent times processed logs were always a luxury good and as such the income-price demand curve means as income goes up more luxury goods are consumed then in my area firewood sales should be buoyant.
  15. Moisture content of this 500kg wood? A tonne of freshly felled pine occupies about 1 solid m^3 and has about 400kg of dry matter, chop it up and it probably occupies 2m^3 of space. Chip it and it is a heap of ~3m^3 1 kg of wood at 20%mc wwb contains about 4kWh It's an interesting comparison because I think you buy your wood in green by the tonne, you then season it in the round prior to chipping at around 20%mc So your air drying from ~50% MC to 20% mc changes the weight and increases the calorific value.
  16. Who empties them? Who pays? Our local civic amenities place wouldn't allow the charity to take the dog crap to their residual waste skips because it was commercial hazardous waste.
  17. Technically I'm unemployed but will be retired by Xmas, I too drive slowly and try and avoid sudden braking, mainly to get a bit further on my fuel, up to 70mpg with the pug206 or fiesta eco where other drivers were getting in the forties. I do have to keep aware of those following, often tailgating, so I seldom go slower than a 30,40 or 50 speed limit but stick to 56 on Mways unless on a long journey.
  18. I didn't realise they had even built two forwarders. My friend in Wales was very impressed with the demo he had of the trailer which was PTO powered with a friction drive via a lorry drum brake.
  19. That's not before time, I'd not noticed the change but then I've not used a post 2010 model.
  20. How should one differentiate between solid measure and loose?
  21. 1000 tonnes/hour is about 5GW of thermal input, at 35% conversion to electricity That gives about 1.75GW electricity out. We peak about 50GW on a winter evening.
  22. Lovely, very quick and ingredients less than £3. should last me the week for lunch.
  23. It's the saw I used most but I already have two or three left over.
