Re: chain saw chain sharpener used on the saw
I would recommend a manual sharpener over a power grinder for a couple of reasons, they're cheaper, they remove less of the tooth and they're more accurate. I've had a power grinder and you're going to spend more time and money buying new chains than if you do it manually.
I have both a manual apparatus and a hand file that I use. I find the apparatus a bit of a pain to use, so I use the hand file and a gauge. After 3 to 5 hand sharpenings I'll take the chain to a shop for a pro sharpening.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
