Just a word of warning about electric chain sharpeners in general, usually they heat up and temper the chain so making them really hard to sharpen by hand with a file later.
Prob won't be an issue for most folk thou, but just incase
Must admit ur metallogical knowledge far far outstrips mine, which is basicly nil as i have just proved
But if u speak to any wood cutter they will tell u machine sharpened chains are a pig to sharpen with a file, possibly i have the reason wrong? just wot i have always been told in past. Same as if u catch a piece of glass with ur chain ur as well just throwing it away as can be hard to sharpen again, no idea why
Must admit never used an electic sharpener for that reason and the only boys that i know that use them are harvester operators and they always have plenty of spare sharpened chains with them. Some of the older skool boys would give there chains a hand rub with file but said was a waste of time if been previously done on machine. But not always easy to stay in front if ur in a caravan for 5 days at a time, have heard of them keeping a couple of chains back un machined sharpened incase they ever run out of chains.
As someone who sharpens a chainsaw on a daily basis, I can say with confidence that these electric ones are crap. Don't waste your money. They DO harden the chain, a friend offered to sharpen one of my saws with one and not only was it not as sharp as I can get with a file it was also very hard to sharpen afterwards. Saw chains are made of a medium hardness steel which has a thin chrome plate on top, it's the chrome plate that cuts, which is why when you hit stone or dirt and wear the chrome off the top of the tooth you have to sharpen right back to the chrome to get the best results...
there must be some younger men than me on here lol i'm 44 and a climber and at the end of the day the last thing my destroyed arms need is to start hand filing chains
Little and often by hand using a guide and a decent chain file, easy peasy, I give mine a little polish up on each fill up while having a cuppa
always ready to go that way
