Sharpening chainsaws

[BlueKnife]

Pretty much any method of sharpening a chainsaw could work with enough experience. I think the learning curve for an average guy to pickup on was the whole point of the video.

True. Then I wish he had at least included some decent hand files instead of those garbage Chinese ones.

Taking the depth gauges right down to the top of the links is going to cut a little faster in a long kerf, if you have the horsepower to pull it, but would make the thing totally unusable (if not)

I have a chain, brand new, ms462, 24in, rakers filed to .60-.07, and, unusable, all grabby and wonderful. I wonder how short of a bar it would take to get it to pull through. A 2:1 sharpens really well with slight sideways pressure, and really poorly with excess downward pressure.

Taking the depth gauges right down to the top of the links is going to cut a little faster in a long kerf, if you have the horsepower to pull it, but would make the thing totally unusable in any cut lacking a flat kerf at least 3 cutters long (e.g. 1.5" for 3/8" chain). Rock that chain a bit in the kerf, or put it onto a branch that's only 4" diameter with a curvature too great to catch 2-3 cutters, and it's just going to grab and stall.

You’re talking way beyond practical hp to pull a chain with the rakers gone. I don’t use a depth gauge on the rakers and just bump them on the bench grinder every now and then. The grinder leaves visible scratches across the raker that start to polish off with use. I usually won’t grind them again until the previous scratches are mostly polished off. A 16” diameter log can easily stall a 500i if I get them too low. You can control the saw enough that it’s not grabbing all day but you can’t pivot it full force off the dogs either.

I've done a lot of milling with 0.5 - 3 tpi hook tooth blades on a bandsaw, and I'd expect the same rules there to roughly apply, when using a chain with the depth gauges removed. Generally speaking it becomes a self-limiting mechanism, as soon as you have 3 or more teeth in the kerf.

Depth gauges set at .025 may cut a little slower than .035, but taking them down to .100 probably isn't 3x faster than .035, as one tooth begins to act as the depth gauge for the next.

I haven't tested this, but that's what I'd expect, having spent more time at a bandsaw than most. For me, just taking the depth gauges down .01 below factory gets the job done at a speed/hp compromise that keeps me and my saws happy.

I don't really enjoy sharpening chainsaw chains. Does anyone have tips on sharpening as well as a good file? Also does anyone use carbide tipped chainsaw chains. Were they worth your money? Thanks!

It doesn’t excite me much either!
In the UK I have used a company that takes your old chain and sends you a matching refurbished one for a reasonable fee. Works for me as I don’t do a lot of sawing.

Check out the Stihl/ Pferd 2 in 1 files, makes quick work of filing and is pretty easy to do. As for carbide chains, if you dont enjoy sharpening you will really hate carbide.

the Stihl 2 in 1 is the easiest / quickest and does a great job after you learn how to do it, takes a bit of practice. Dremel takes too long for me. Either way, it’s a tedious task and a dull blade is useless.

The Stihl 2-in-1 (basically a relabeled Pferd Chainsharp CS-X) is probably the easiest to learn and the quickest to use (adjusting the depth gauges at the same time was a great idea by Pferd). It gets good results as long as the user pays attention to a couple of things: keep the tool moving in a straight line when filing and use appropriate pressure. Too many new users drop their hand down as they make the stroke (tipping the opposite end of the file up) or swing the end of the file left/right. Using 2 hands on the tool can help avoid this, though it does mean using a vise or some other method to hold the saw still while sharpening. Those with a bit of experience, can get the same results filing one-handed, but the two handed method is a great way to build the muscle memory of what a proper filing stroke should be.

The Husqvarna roller guides can take a bit more practice to get the hang of. However, once you get the hang of it, they get better results. They do require filing the depth gauges separately, but that is also part of the better results: the progressive depth gauge tool is just a better way of setting the depth, customizing each raker to the tooth which follows it. (rather than bridging 2 or more teeth as some other depth gauge tools do.)
