  1. We're in much the same position with our field entrance, they can't stop us using it but won't allow an extension to the dropped kerb to avoid lorries running over the verge. Highways authority can grant the permission themselves in which case no planning permission is required.
  2. Get it diagnosed with the Ford IDS program, it could be something quite simple That will have the 2.4 common rail engine which shouldn't show much wear at that mileage but fuel pumps do wear out and often the debris damages the injectors. Typical early warning is the error code for low pressure at cranking.
  3. Take heed of what others have said, it can't be worth it, however: When I was very much younger and even more foolish in about 1974 we were felling the last 3 big dead elms on the farm where I lived and after the butts were taken off for milling I needed to get rid of the stumps. I came across a stump grinder that fitted on the back (and underside) of a MF165, which was our big tractor. It was called a Myers-Sherman and consisted off a frame with a pair of telescoping tubes and a drive shaft between them that came straight off the PTO and then a multi belt drive dropped down to gear up the head. The cutting head was two wheels on 5the same axle each of which used the same teeth as the little Vermeers which were popular then, you had left teeth, right teeth and straight teeth. The pockets attached to the wheels at two differing radii, so as you dragged the cutter head in and out from the tractor 4 or so cutters worked on the face of the stump, one set on one wheel pulling and the other set on the other wheel pushing. After a week or so of hacking at the stumps I had got them all below plough depth, I could do the same job in less than a day with the big Carlton now but things kept breaking and going wrong. I was left with the machine stuck on the back of the tractor without a use and having seen an exenco chuck and duck chipper I had an idea. I rearranged the teeth so they were all level and by putting the wrong handed cutters on the wrong wheel I was able to just about have a complete cut over the whole distance between the wheels and inside the bearings. I fabricated a short feed chute with an anvil made from a blade off a Kidd forage harvester welded on such that with the grinder closed in to the tractor and at maximum elevation I could feed a holly branch through it so the chips just flew out the back tangentially to the wheels. It whipped the branch out of my hand , shredded the side branches off but spat the main bit straight out the back about 30 yards through the small gap between the wheels which I thought was covered by the cutters. I thought it had potential but couldn't play more as the tractor was required for normal farm duties. The grinder came off and languished in the nettles until the dispersal sale when the old boy retired and was put in a one bed council flat, I think I did actually see it again, or bits of it heavily modified, on a ex FC roadless articulated skidder many years later
  4. A recent change in building regs makes 125mm flue acceptable with approved stoves. Is the single storey extension open to a 2 storey building that is centrally heated? I had the case of a rayburn that would not draw and I think it was because the rest of the house was warmer so there was a circulation from the kitchen (extension) through to the living area and then up one or more chimneys in warmer rooms. It should have been okay once everything was up to temperature but the(new) owners gave up on it.
  5. Yes as soon as the total weight exceeds 3500kg you need a tacho unless used under one of the exemptions, the exemption that principally applies is if the equipment is for use of the driver at site which is within 100km of base. The plates on the vehicle for GVW, axle and train weights are maximums, the maximum towing weight is as specified by the manufacturer. So if the Gross Train weight is 7000kg and the manufacturer specifies a 4000kg trailer with brakes coupled to service brake then the maximum weight of the towing vehicle must be below 3000kg even if that is less than the GVW
  6. Interesting little video Wood on Wheels | WoodlandsTV his material seems a bit less than the best because of the knots. In the good old days of chestnut coppice the local walking stick manufacturer used to insist on sweet chestnut that had grown 4ft from the stool in one season to get clean sticks. Similarly cricket bat willows had any adventitious buds rubbed off the keep 12 ft of clean stem. So simple cultural techniques should improve the strength. I am fascinated with the possibility of a biologically derived epoxy resin but think I would compromise and use carbon fibre instead of the natural yarn.
  7. If this turns out to be a duffer TCD and Shavey should have warned me off it I've got a number of saws that I have got going again and intend to offload them once I have played with them, proceeds to charity.
  8. I finally bought a clutch cover, I'm still missing a chain tensioner and I suspect bar plates plus a chain and bar nuts and I'll be able to try it out. Macpherson said it was after 1980, anyone know which models had points and when solid state ignition? It seems quite fat for a snedding saw compared with a 254 of the same era.
  9. It's not other fuel you need, just some more sticks to mutually radiate heat. Try it. In free space the wood can radiate its heat away so well that it drops below the auto ignition point of char, once the char surface falls to below about 200C it does not have enough energy to dissociative an oxygen molecule , place it on a bed of ash and you half the angle through which it can radiate, place that in an box where the walls can re radiate heat back and it will burn to ash. This is how andirons were used to control the rate of burning of cordwood so the fire was just at the point where two or three logs met.
  10. Yes and its other advantage is that it doesn't produce sharp splinter, so when it snaps it isn't dangerous. No wood will support a flame as a splint on it's own (unless a resin pocket present??) so the wax is necessary.
  11. It's not much different from the way mining has gone, it becomes far cheaper to move hundreds of thousands on tonnes of overburden to get at a seam the other side of the world than to pay UK labour rates to deep mine. The thing harvesters have done is drop the harvesting rate/tonne in real terms, this has affected the roadside price and made the cost of getting timber from small or awkward woodlands higher than the roadside price (I would drive my outfit to site, extract 3 loads onto artics or roadside and move on, the same job now with mechanised kit would involve 4 lowloader movements at over 300 quid each and 2 hours actual work). When we first saw harvesters in the late 80s they weren't that productive and their costs were higher, so I clung on to hand cutting, but they got better.More significantly when trade turned down and things got more cut-throat firstly it was cheaper to lay subbies off than stop finance payments and secondly those businesses with harvesters that gave up put cheaper second-hand machines into the market, making them more competitive. ...and remember timber and coal were linked as strategic supplies so were subsidised. As civilisation cannot survive a modern large-scale war so now fights using proxies the economic cost of maintaining strategic supplies exceeds the demands of an affluent society for consumer goods sourced from abroad. I went in to forestry because I naively thought a production industry was good for the country, it also gave a good lifestyle, but the service industries, including arboriculture, have mushroomed since then whilst all the primary industries have shed vast numbers of workers.
  12. They obviously have no value, we picked up some sainsburys' ones that had been discarded on railway land, sainsburys wouldn't pick them up from our yard.
  13. I tend to blip the throttle to avoid the cut out but I agree most people seem to run them flat out. I tried to demonstrate my technique to some railway deveg workers but they just looked at me like I was a madman. From a pollution point of view unless the engine has a catalytic converter, all the time the rev limiter kills the spark unburned fuel mix just gets vented to atmosphere. I don't know the significance to the environment but it sure blocks up spark arresters, and no I don't remove them because they make the machine noisier in an urban environment and night works do offend occupants of houses adjacent to the railway. I heard of one chap who came off shift to find his car had been pelted with eggs.
  14. You need to find the time constant of the slab, the time it takes to reach an equilibrium from a stepped input, so you can predict how long it takes the slab to cool to half its normal temperature , this coupled with a predictive programmer that compares outside and inside temperatures should be able to decide when to start pumping for the morning demand. Whilst I have worked on installations using thermal stores and underfloor heating from wood firing I have never lived in one. What I have discovered is that a high thermal mass underfloor heating system doesn't really suit a couple who both work away from home 11 hours a day. I'm thinking I may have to compromise and fit a kick space fan coil unit for the sitting room. This is in a gas fired one bedroom bungalow.
  15. This is where underfloor heating scores, not only do you have the thermal mass of the screed but that delta T could easily be as much as 50 deg C, effectively doubling the water heat store as long as DHW is separate.
  16. You will still need O licence but no tacho if you drive the digger and are within 100km of base.
  17. Good point. Also the reason stihl drills and hedge cutters that have an ignition rev limiter foul their exhausts with tarry unburned fuel if people insist on holding the throttle open all the time.
  18. Our blokes had them for cutting dirty timber on a fencing site, including cutting roots. They say they were never anywhere near as sharp as a normal chain. Trouble is most of them were discarded before I bought the diamond disc. So for general use it will always be quicker to sharpen and use a normal chain. If you are close I could have a bash at sharpening but that earlier quote looked very reasonable.
  19. Yes and that example of the 5.2 Iveco is interesting, it will always need an O licence The interesting thing is it can also tow 3 tonne whilst fully loaded minus the nose weight of the trailer. how realistic is that 2800kg kerbweight for an iveco tipper?
  20. I have one on a ms200, only got to a couple of points with 7 minutes use. I have to program in each saw's front handle acceleration from manufactures data which is a bit limiting. Poles saw seems to be a good contender but havn't tried it yet and which hand should it be nearest?
  21. Yes I suppose the reasoning is that B+E is what is needed for personal use, e.g. caravans anything heavier is commercial so can be limited without infringing personal rights. Now what does one do to avoid lapsing the LGV and HGV entitlements?
  22. I'm using a lidlaldi grinder with a 4" diamond disc for sharpening circular saw blades, with the stihl tct chain. Trouble is I've never had a sharp one to compare my results with but it's certainly usable whereas before it was to dull to cut.
  23. Only if the gross was less than 7.5 tonne, what's the kerb weight of the Iveco and the weight of the digger?
