Anyone ever use one of these ? I've had one un-boxed in my garage for about 20 years now . Is it even worth trying or does it mess your expensive chains up ?
Out of the box don’t expect great results. Mine had tons of slop in every mechanism. I have heard of some people drilling, reaming, and bushing hinge point to remove the slop, but I opted to throw it away.
Ive seen electric sharpeners in use and don’t care for them. Have to maintain a radius on the end of the wheel or it doesn’t give you that nice dish in the tooth. I don’t think they grind the flat that controls tooth depth of cut.
I personally love hand sharpening a chain. nothing like a new file like shredding parmesan cheese.
Which isn't much ! I just took this thing out of the box . Mostly all plastic . I may just try it out on some of the cheap Poulan blades I have hanging around . If it works somewhat , I'll keep it . If not , it'll go out to the trash man .
Earlier this year we had an arborist come to remove several trees. We've used him over the years and have become friends. I ask him about using an electric sharpener and he had to chuckle. He replied it's a skill most arborists learn in their apprenticeship years, just like a machinist learns to sharpen drills.
He did say that while they do work it's much easier and faster to sharpen them on the saw with a file. As I watched he sharpened a blade on a 16" saw in short order. He said that once you learn the technique it takes between 8 and 12 strokes to sharpen each cutting edge. He had the chain resharpened and up and cutting wood before I' would have been able to remove it.
