  1. this but I do read stuff on the smartphone when away from home and occasionally make brief replies
  2. 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.
  3. 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.
  4. 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
  5. 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.
  6. It's worth learning to splice for this sort of thing.
  7. Pete W found a url that does it, I just have it as a bookmark tab
  8. Sorry my mistake then, you did mean measure the ring, not something I ever did as a wide ring gap meant a new ring for me. I never found a nikasil bore which was worn other than ones that had obvious damage.
  9. but you were doing more than +10%+2 at sixty as you should only have been doing 50+10%+2=57 to get away with it. What I'm trying to establish (in general not just your case) is do they only nab someone for doing over 60 and then check if it's a commercial and thus impose penalty for that infringement. If it's a policeman holding a radar speed gun I can understand him making the decision on the spot, or if a police car has followed you for 220yds and decided you were speeding (in my youth I passed a stationary police car on the M4 doing 106mph and he pulled out to chase me, I soon saw him and slowed down and was pulled over, I got a dressing down but they couldn't prosecute , no on the spot fines then, as they had not followed me speeding for the full 220 yds required then, licence remained clean for another 30 years before I triggered a 50mph camera at some roadworks) but the concern is how "intelligent" mobile and static cameras were.
  10. In that case why would it not have mattered if you were doing more than 50 but less than 60?
  11. If it isn't obvious because Spud made a typo putting ring where he meant bore: You put a bare new ring in the bore and square it up with a piston, you then use feeler gauges to check the end gap of the ring. Repeat this in several places of the bore. If the gap doesn't vary and the gap is negligible the bore is okay and you may get away with just new rings. I'm not sure of the correct ring gap but it shouldn't be more than 15-20 thou. You can use the old ring as it's the variation in the bore that you are checking to see if it's worth reusing.
  12. They can both do 70mph on a motorway. unless they are towing, as they are less than 7.5 tonne gross and they should also both be th same on A roads i.e. 50 on single carriageway and 60 on dual. The exception being dual purpose vehicles which can go at 60 and 70 on A roads. I don't believe a transit pick up can qualify as dual purpose but many 4wd can.
  13. They are accurate as the velocity is calculated directly but not necessarilly precise because of the geoid that is programmed in doesn't exactly match the hills and bumps you are travelling along. I reckon +- 2mph on mine on a flat straight. No thtat's just to give the police a good margin for the court to accept and it's discretionary, I'll bet it is tighter on average speed cameras. The regulations allow a speedo to over read by 10% and under read by 0% so when my fiesta is showing 80mph the sat nav averages out at 73. Which makes it only just inside the regulatory requirement. Lorry tachographs seem much better. RDS (who supply the engine management and stress controls for some chippers) used to sell a radar that read the speed from reflections from the road surface which was spot on. Same was true when I had 7.50 x 16s on my LR 88.
  14. OFTEC is about domestic oil heating isn't it?
  15. Not if in the course of business. Domestically you can store up to 3000ish litres in a single skin. On mobile kit, like bowsers and grab tanks there are also rules on where the taps areand whether they are lockable.
  16. 201 litres anything more and you need a secondary containment with 110% capacity
  17. I just came home on the bike up the A303 at an indicated 73 (optimistic Honda speedo as I was following some lorries which were probably doing 56 and it showed 60) and was passed by several commercials.
  18. Can you elucidate? Was it a static camera clocked you at over 60 and subsequently the picture showed you were in a commercial vehicle so you got done for that?
  19. I camped next to the ahwi 400 to look after it on a dodgy site but the boss deducted my b&b allowance so stuck with hotels after that
  20. Seeing as you cannot exceed 40mph anywhere near your place that'll be no great hardship ?
  21. Thanks for saying, was the actual speed more of less than 60? I want to know to understand why the camera was triggered as presumably it didn't take pictures of cars doing under 60. The thing is this information is not available under FOI requests and most is anecdotal.
  22. Can you explain the reason you were stopped and the outcome?
  23. The DPF traps fine particles which consist of soot and polycyclic aromatic carbons adsorbed onto them. When it regens, or indeed any time it is hot enough it turns the carbon into carbon dioxide and the PAHs into carbon dioxide and steam.
