  1. Is he the guy from the chip shop??
  2. Has anyone tried running a ms260 with just one ring fitted? it always seemed sensible to design with two but the equivalent Husky 254 only has one
  3. Yup I've learned how to flip images but how videos?
  4. That's interesting, I didn't use a timberwolf with stress control until around 2000 after they morphed. It made me realise how much more productive it could be to just stick a piece in and walk away knowing it would cope rather than tend the Dosko. The Dosko is still going but the loss of productivity over the years must have made keeping it a poor choice. Later I realised the "letter box" opening was of value when chipping conifer tops which would bunch up in the 6" square opening and then marvelled at the aggressive feed of the Forst 6". So if the parts are available a retrofit should be okay. Some chippers seem to use the alternator W output for speed sensing so no longer any need for the toothed wheel and hall effect sensor. The first generation of stress control was very simple in that the tachometer sensed rotor speed and switched a solenoid spool in the feed to the main spool such that the hydraulic pressure was all dumped to tank. If the blades were very aggressive they could continue to pull material in by over running the feed motor(s), I don't know how this is managed nowadays whether by blade angle design or using an over centre valve on the output of the main spool to feed motor(s). The hysteresis of the speed controlled switch meant that high idle had to be reached by the engine before the hydraulic flow to the feed spool was restored. Logically you would cut the feed when the engine fell to the revs for maximum torque, in practice manufacturers seem to cut out and back in nearer to maximum power.
  5. I was going on the angle of the dogs as well as the back handle and trigger. Looks normal one tooth, tie strap then opposite tooth to me.
  6. A deafening silence from the experts probably means this question is a bit too contentious. I suspect compliance is the major issue as chippers can be dangerous and modifications that are not approved could lead to problems with H&SE if and when something goes wrong. Does the Entec conform to the required hopper and feed chute dimensions and stop controls? Mostly it's probably not worth doing, mind I'm speaking as someone who has spent a few hours each day for the last two tending an ancient chipper with no stress control on some leylandii tops and I'd guess 30% of the time was necessary just to prevent jams and stalls which would not have occurred with a modern 6" chipper but then will these modern chippers still be working everyday after 30 years?
  7. Yes the only drawback is that it occupies quite a bit more space in the log store. I'm beginning to regret having so much softwood in mine this year as I have had to turn away some ash as shed is full.
  8. You're right of course but I just apply a grease gun to the hole and screw the grease in with the plug on Stihls.
  9. A close up of the snapped shaft should show if it was previous damage and then a fatigue crack leading to a complete break.
  10. The toothpaste tube of stihl grease screws directly into the gear head hole on their hedgecutters, just squeeze it in till no more goes in and put the plug back in. My Makita has a grease nipple which is more convenient. I gave up checking my Husqvarna strimmer heads as they didn't seem to lose any.
  11. That's probably all you can do but it may not just have been a period of drought but some other environmental factor affecting the roots.
  12. It's obviously not happy but removing the dead bits would just be removing the symptoms, the problem will be with the root system's ability to deliver water to the foliage.
  13. I'm not going to comment on whether requiring facemasks to be worn in shops was worthwhile, I have donned one twice to go shopping. However a surgeon or dentist wears them for entirely different reasons, to prevent splashes being inhaled. Mind I was most surprised when my dentist started using them 20 years ago and wondered what had prompted it at the time.
  14. A chap I was at school with wrote a novel about it never let me know, I've not been able to read it beyond the first few pages.
  15. snap but my car is somewhat younger, actually it's the wife's but she won't drive it anymore
  16. Nor me but I had thought we were discussing this in the context of using a machine to pull the rope and joining a snapped rope.
  17. It was lopped topped and dropped
  18. Yes I forgot that, the second car the grandaughter had when she got her own insurance had one plugged in to the OBD2 port and she was supposed to not drive between 2300 and 0600 but she paid no heed to that.
  19. I've been through this 3 times over the last 30 years and I found the cheapest in the long run ( up till about 25 years old) is to insure a cheap car in the drivers name comprehensive, with a voluntary excess that is the same as the car's value. If it gets written off (none of my girls did) then you start again. Some say the premium comes down if a parent is named on the policy, with NFU it made no difference. The girls took out their own policies after the first year by which time they had full licences and a years NCB. It fell apart for me with my granddaughter who abandoned the little pug 206 she had been given and proceeded into a string of hire purchase disasters with equally disastrous insurance costs.
  20. I was with you up to that point @Pete B; The issue with diesels regulations is to do with particulates and their inhalation. Not only the micro bits of sooty hydrocarbons but also particulates which form when nitrogen oxides react with other chemicals in the atmosphere (sulphur compounds I think) to precipitate more particulates which can be inhaled. The issue of climate change from burning fossil fuels is the release of CO2 into the atmosphere which petrol engines do as well as diesel engines and just about any other form of combustion.
  21. Were he not the father of the US space programme he would have been tried as a war criminal for the slave labour used in his project I think by war's end the german nuclear effort lagged severely behind. It was a Hungarian, Szilard, that was the instigator of the atomic bomb but it was his persuading Einstein to make a direct approach to Roosevelt that got the Manhatten project going and Truman's right wing bigotry that led to the Windscale disaster.
  22. Just about 100% compliance here, customers and shelf stackers wearing masks but cashiers behind screens not, makes sense to me. I went to use the pay at pump machine and it rejected my card so kept helmet on with visor down, most uncomfortable for the couple of minutes I had to queue in the shop.
  23. I understood alder was used for the bulk of black powder but alder buckthorn for the fuses, it grows fairly commonly near here (and I suspect Aldershot 15 miles away). My guess is got the name alder buckthorn because of its similar habitat and use.
