I see it was 2008 when the problem was last mentioned on this forum under it's proper heading. Been lots of questions from various folks since who are obviously still having the problem.
I see over the years, no-one has dared to offer a fix for the problem. There must be countless tonnes of carving chains and bars discarded every year just because of this problem (especially given the number of new chainsaw carvers coming on board each year).
I know it is a bit of an invisible problem because a lot of carvers regard bars and chains as totally disposable items after completing a job (it's costed in on the contract). However, You can extend the life of these bits of kit with a bit of TLC. In this way we can reduce our draw on our poor mother earth who has to supply the minerals and the energy to process them at our ultimate expense.
Please take note.
