  1. Tail of the cow, it's the way the stain looks sh*tty as it runs up the end grain, phrase was taught to me by the veneer buyer I used to fell for
  2. The "queue de vache" in those pictures show why it's best to mill sycamore the day it is felled. The saying was "fell on Christmas day mill by boxing day. Brush off sawdust and initially stack boards vertically
  3. I think the statute of limitations would mean they could only bill for 6 years
  4. I've not been involved with any high speed tractors so don't know but most arb use comes under horticulture doesn't it? If so presumably this is in the agricultural and forestry exemption? Again with the exception of a trailer with unladen weight under 1020kg and powered brakes which needs no test. I am not a fan of overrun brakes where the gross weight of the trailer exceeds that of the tow vehicle so it's an interesting idea to me. Its only of academic interest to me now but when I was looking at the dutch 5th wheel trailers they had electric brakes and yes I would consider them to be powered.
  5. It could of course be fitted with "coupled" brakes and still be under 1020kg unladen and hence not need plating, the unladen weight over 1020kg AND power braking is the special case. Of course anything over 3500kg cannot be used with overrun brakes, so it's anything with a MAM of greater than 3500kg needs plating. Big chippers on overrun brakes will be exempt as under 3500kg anything bigger tends to come under agricultural machine. I may be a little out of date having lost my job nearly 2 years ago but I still occasionally get calls from people at the old firm, one of which recently was about towing a trailer with overrun brakes behind a six wheeler, it only required an inspection for the trailer hitch and the extra train weight.
  6. I had to look that up! It's apparently from latin for trunk, so over trunk??
  7. Epi means over, as in epidermis being the layer over the dermis, so the epicentre is over the hypocentre of an earthquake. hypo meaning under as in hypodermic, under the skin
  8. I think most firms charge about 30 quid for a consignment note, all hazardous waste requires one as part of the chain of custody, 5 batteries or less is allowed to use a shorter reporting method but consignment note still required. I only thought of two work arounds, first was to drive vehicle to waste disposal premises and change battery there, as it only becomes waste when changed, second claim the batteries came from litter picking on Network Rail land as they had an exemption to take hazardous waste directly from railway to a licensed premises.
  9. Mine too but I think it refers to whether the cat's claws are out of its glove. I find it difficult to wear gloves for fiddly work but would advise those that get used to wearing them early on to continue to do so, apart from scratches and cuts they help protect skin from contamination as well as HAV.
  10. Some while back we discussed 5th wheel outfits of 7000kg gross train weight, these have to have powered brakes and it seems unlikely they can come in under 1020kg thus they would require both annual test and an operator's licence. Which is why I stated over run trailers were exempt earlier in the thread as they cannot exceed a MAM of 3500kg
  11. There is one type of trailer under 3.5 tonnes gross weight that needs an MOT that's if it is over 1020kg unladen AND has brakes operated via the vehicle service brake. As you say then it would also be subject to operator's licence.
  12. I cannot remember but it was seconds rather than minutes
  13. Back in 74 we tried steel line in place of a brush cutter blade ( before plastic line was available) and it fatigues and snaps in short order.
  14. You would need to tune the length of string to the power band of the engine, make it a bit longer and it won't rev high enough. You can severely overheat a strimmer motor by dropping the revs with too high a load.
  15. Power requirement goes up with the cube of the air thrashed about (roughly proportional to length of strimmer line) a large steel blade would sap less power and not send bits of plastic everywhere.
  16. The power a winch can deliver is limited by the friction clutch, overload it and it slips, unlike the bad old days when the clutch of the tractor controlled the winch. The limit the winch could pull was then either the log moving or if it got stuck and one didn't declutch either 1 something broke 2 the tractor went backwards 3 the driver baled out as the tractor overturned (RIP John Lamb) or the tractor climbed the tree My Igland 4000/2 has a double sprocket, the smaller one results in faster line speed for highlead work but using your figures and a bare drum lifting a 4000kg weight gives:- Force=9.81 x 4000 Newtons Power-force x velocity= 9.81 x 4000 x 0.9=35316 Watts or about 47 horse power As the drum fills up the torque delivered by the clutch remains the same but the line pull falls and the speed increases.
  17. I've no idea but it looks like a polyurethane paint that cures with damp. What would worry me is the concrete has cracked because of settlement so something that just covers a crack is likely to fail when it moves again. Butyl liner will sort that. Have you considered cleaning it, painting on OPC and SBR neat then making a ferro-cement creed with chicken mesh?
  18. Is there a blade available for a normal B&S type cut and collect push along that has more of a vacuum effect to better suck up lawn debris?
  19. My understanding is the patent on the basic ingredient, glyphosate, ran out so in order to maintain market share monsanto got approval for slightly different product types which are thus still in patent.
  20. Al you are a gentle person ?
  21. this but I do read stuff on the smartphone when away from home and occasionally make brief replies
  22. Yes I understood this after your last reply. As I said it's not something I have ever done as the first thing to show up would be the large ring gap which would mean a new ring either way. Yes, Nikasil is hard and only .4mm thick I think. It was cast iron bike engines we used to check the ring gap in several places down the bore to decide whether a rebore was necessary. In those days british bike engines seldom lasted 50k miles without a complete rebuild.
  23. I had one as a estate truck on a Y plate. It weighed about the same as our 2004+ transit tippers at 2.1 tonnes but carried the load less well and was a bit underpowered. It meant it seldom was overloaded and was the most reliable until a new driver rear ended a car and it was written off. From my workshop perspective transits may have rusted but that was cheaply repairable with on site labour. The spares were reasonable and the drive comfy. The 2.4 duratorq engine tended to need new fuel pumps around 120k miles. OTOH the two Canters I sometimes drive carry the load well, such that they regularly go over 4 tonnes and no one notices, the chassis and tipper frame on the 59 plate one are rusted badly and the tipper body will need replacing and they are uncomfortable, especially on poor roads. The spares are excruciatingly expensive and the 03 plate one with only 107k miles on the clock has just cost £1500 to have the fuel pump re calibrated.
  24. None that I have. You first mentioned knots in polypropylene rope jamming pulleys and a simple short splice of a total of 6 tucks will do this, essentially making a short length of 6 braid. I have never faffed about with long splices as they take up a lot of rope and time. I used to join wire rope but again to do that properly in the field is beyond me. So I developed a quick system for joining ropes by making an eye splice at the end of each wire rope, which is simple, and then joined the two with a quoit made just as simply by laying up a single strand 6 times and tucking the ends into the middle. One thing I did to facilitate this was to seal the ends of the strands with oxy acetylene before I started. A video of the quick eye splice: For forestry use you can't leave the end as he has done, instead separate the tail into strands and twist it around it's adjacent strand in the live line at least three times, this is like taking each strand and making a loop like a timber hitch in each strand. You should finish by taking each strand to a different number of tucks and then removing the core to the full length of the splice and tucking each strand in to form the core, one after another. I never bothered This is plainly more than twice as bulky as the wire rope but it did pass through the high lead pulleys and Igland winch fairleads
  25. Yes it essentially fixes it as green wood, as the cells remain full there is no shrinkage and the wood remains as heavy as green.
