  1. That was my thought if it is steel or. if the clamping is tight enough, do away with the tightening system and tension it by hand, then clamp.
  2. I was referring to the circlips that have tangs on them, I dislike them because of the OP's sort of failure. I was musing about how orientation may affect how metal fatigue may cause the tang to break off in use. I don't have enough experience of stripping a lot of saws so I do not know if circlips with tangs are used on original builds. My limited experience with Stihl and Husky saws is the OEM circlips have no tangs, so I stick with them. Yes it is important that the circlip has expanded into the groove firmly. I have yet to see the tool for inserting circlips without tangs that @adw uses but plainly the ones with tangs can be abused and bent getting them out and in with a pair of pliers.
  3. I wonder if the orientation of the tang makes a difference, my thought is if it is vertical it suffers a bit less bending stress than horizontal so could fatigue would be less.
  4. The base of the tree doesn't seem to get damaged by fire unless the fire actually burns it. Most of the damage is done when radiant heat breaks down the proteins in the cambium and the characteristic pattern of necrosis tends to look like an assegai spear blade, broadly curved at the base and tapering out at the top
  5. Strange, the few stihl saws I took apart the gudgeon pin circlips had no tangs.
  6. I don't know, just pointing out they can. I don't believe the pollution from a modern wood stove is as bad as they say either.
  7. Yes I don't think they differentiate particulates from different types of carbonaceous fuels but they do tell the difference from particulates from brake and tyre abrasion because of their chemistry.
  8. Misread it was for the grinder
  9. Particulates from combustion have a different chemical signature from other particulates.
  10. Most EVs do not pay any fuel tax (other than the 5% VAT on domestic electricity) as they charge from home. So increasing fuel duty just increases costs for older cars that then get scrapped early (don't get me into what silly faults make a car uneconomic to repair). With 2% penetration of EVs into the pool of cars it won't be long before they devise a road usage tax.
  11. It depends on the provenance (genotype) and perceived wisdom is that it needs to be done when the stem is less than 35 years old.
  12. It may help if people know the rough location.
  13. One is a criminal offence the other a civil one.
  14. If I don't hear the bang from 70 miles away you can always drop in for a tea if you go home clockwise then north.
  15. Which ones?
  16. I suppose that stops you driving for a while? Best wishes for pain relief and recovery Eggs
  17. Well as things get worn the chain can snag more easily when you pull it back, if you do it with an ungloved hand it can injure. If you use the file and it jams the file can take the tip off a full chisel file. I move the teeth forward with the file on the back of the cutter for the left hand set and my hand with the right hand set as I advance those two or three cutters and sharpen them in one position. Mind I only sharpen a chain occasionally now whereas it would be a light touch up several times a day at work.
  18. I never pull the chain back, only forward.

  20. Reuse the Stihl ones or buy genuine circlips for the aftermarket pistons
  21. It looks like the sort of damage you get when an aftermarket gudgeon pin circlip has shed its tang.
  22. 6 to stop the handle falling off 7 yes you could move it up and down and bend it a bit straight but it will never be good enough to use so follow @GarethM's advice then buy new
  23. I seldom go shopping and use the "pay at pump" machines at petrol stations and buy most toys online else always pay cash whenever I can. I also wonder who pays for those ATMs? As only the amount drawn out shows on my statements.
  24. If you want to take it on road at all look at the tyres as mine are marked not for highway use.
  25. They do and the fuel air mix also passes over the valve gear and into the crankcase, lubricating them so they still need a petroil mixture. Also I think that on the induction stroke some of this mixture is pumped into the cylinder.
