How to Sharpen Garden Tools : Mechanically Sharpening a Chainsaw

[donyboy73]

hi Fred, i have the same machine

[mortie806]

i bet it would cut great if you brought it to a pro but hes no pro

Wow 30 years of doing it totally wrong. 30 degrees pitch and 40 degrees undercut. He never used a limit stop he probably cut halfway down into the strap, and he didnt cut down the rakers at all. It takes me about 5 minutes to properly sharpen a chain, this is probably the worst sharpening I've ever seen.

I think a machime will produce the needed repeatable accuracy far better than anyone with a hand file. Each tooth must cut its share for greatest speed.

I am puzzled why you did not lock the chain prior to each grind. This may take time , but it prevents the tooth from rocking in the grinder as it being ground.

i would beg to differ i think for the most part race chains are hand filed. but im not 100% but i would imagine that a machine couldnt quite replicate the results.

[RamThisDTO]

A hand file is totally uncontrollable as far as how much you cut off each tooth, proper angle, etc. A GOOD electric chain sharpener with GOOD wheels that are PROPERLY dressed for the proper chisel profile, will produce a chain as sharp as brand new. Properly setting your limit stops on the first tooth will ensure that every tooth is cut identical.  This keeps the chain from chattering or sidewalking when cutting.

A machine will sharpen better and quicker than a hand sharpener. Maybe not this machine! But a Silvey or Simington will sharpen chisel bit chain better than handsharpening. The sharpener in the video is made by EFCO of Italy. The older model has a reversible motor so you get a better job-you turn the wheel into the cutter. Also, in this video he does not use the clamp on the machine to clamp down on the drivers while sharpening. That will result in an inferior end product. Rakers?

I heard if you use an electric grinder it takes out the temper.

This is an awesome video. I got a chainsaw sharpenner and the directions were so vague I was not sure how to use it. THANKS!

BTW -- How do you determine the angle for sharpenning a chain? Do I need to look it up somewhere?

[MRkallek91]

LOOK AT YOUR CHAIN ! thats how you "determine your angle".

[soggybuilders]

@willoughbyforest I would just go to your hdw store [preferably] not a big box typ hdw store andlook at the box your chain would normanly com in ,it should give you the angle. Some chains have a mark on the tooth to show you the angle.Or just email Bailey on line chain saw stuff and ask them,they are the best most economical chain saw stuff around.

Even if it's Italian (LOL) sharpening chains by a machine is just lazy.Of course its going to cut like a new one..thats how their done before they leave the factory,but they don't cut that well.use a round or even a flat file,yes it works and it's better than a machine sharpening!!Everytime I get a new chain I put my own edge on it so it cuts better.A real pro wouldn't use a machine on a chain.

[nightriderpsd]

i run a crew of 5 guys in the woods and dont care to hand sharpen all the chains they use but what do i know im not a pro and im just lazy
