I still have my old Silvey grinder. The mistake a lot of weekend firewood cutters make is, they forget to take the riders/rakers down when they file a chain! If they are as high as the tooth, (or higher) your tooth can't cut. You put a straightedge across a couple teeth, and use feeler guage. On my old saw, I like to run them at .027" for hardwood, and .032" on softwood. Also, most folks don't geind the gullets out as often as they should.

My buddy that has been cutting timber for over 35 years has a Silvey and I have not sharpened a chain since I had him do it, flat out cuts wood when freshly ground! I could never file a chain as good as that grinder does.
I've been watching this guys videos, He's is out of bellevue, pretty good videos.This video was really interesting to see how dull factory chains are.Think of it this way.If i sharpen my chain like this in theory i could be close to cutting two truck loads of wood in the time in took me to do one, roughly.i'm going to try to learn and pay more attention to details when sharping my saw.Thought some of you guys might be interested in this.

I could never file a chain as good as that grinder does.not to mention square files cost a fortune and can’t be tuned like a grinder. Silveys use carbide dressers mounted on the grinder to set up the wheel to the operator’s preference.For firewood cutting I only like round ground chain, I leave the squareground for the timber fallers. It does cut faster but once that corner hits any sort of grit it’s all over. The timber fallers I used to know always carried several chains to swap out in the field, don’t recall a single one who would sharpen their chains in the field. Landing guys are a different story, most of them used round ground .404 chain because it would hold up in those nasty conditions.The best tool I used for touching up chains with a file is the Carlton “file-o-plate”, sadly I don’t think they make them any more. With that little credit card sized tool, it would guide your file into the correct location and angle, as well as act as a raker filing gauge that would not only get the raker to the right depth, but the perfect angle as well.
