[QUOTE="Philbert, post: 7773094, member: 12609"] Just a few notes on the grinder comments. Grinders do not overheat cutters if used correctly. Guys with little patience or understanding try to use them like a chop saw and apply a lot of pressure. The abrasive also dulls with use, and needs to be ‘dressed’ periodically to expose fresh edges. I lightly dress my wheels once per chain loop. Put together, aggressive grinding with dull abrasive is like forcing a saw to cut with a dull chain. If cutters are overheated (‘grinder hardened’) they can usually be made fileable again with some light grinding through the hardened layer. The chains are not necessarily ‘ruined’. Philbert [/QUOTE]
