Here is the RS I tried Saturday. I tried tilting the vise both ways and could not get enough hook. I guess I am going to have to tilt the head on the grinder more.
Each grinder may be different in its settings, have to play with each one to get the cutter profile that you are looking for.
30-55-10 worked good on that oregon chain. I think the shape of the cutter on Stihl RS chain is different than the oregon and I am not getting enough hook on it.
I never thought of it that way, but it makes sense that 2 different chain manufacturers could need different settings to make their cutter work good at self feeding and cutting best. That cutter does look like it needs more hook. Could it be that the different chain is sitting higher/lower in the vise as well, causing the grinder to need the different angles ?
It could be the chain is sitting in the vice different. I was thinking it may be the angle of the cutter. That Oregon chain I did was on someone else's saw and I already took it back to him. I wish I had it to compare.
Just an FYI.. There will be a little gathering of folks at my place December 12th. Many of whom, are well versed in sharpening. Any of the followers of this thread are welcome to join, as there will be files, grinders, and perspective to be shared.
Too far is a subjective term. I've driven all the way to eastern Tennessee for some good perspective before.. Lol....
I should make this one. I hope to be able to any way. Have to deliver a mutt back home out there anyway.
Mutt packed and shipped today! I set this time late so you could attend one finally! It's been a couple years since Terry's place eh?
Haven't read the entire thread . So, forgive me if this has been mentioned . Too minimize overheating your cutters ,start with a clean chain and wheel . If your wheel picks up the oil and mung off the chain ,it will not cut as well ,and it will require more pressure to cut . The chain doesn't have be spotless ,just reasonably free of oil and debris . If your wheel is black on the cutting surface ,dress it lightly to remove the oil and ground in dirt . This holds especially true on chains that are rocked ,or require heavy reshaping .
I was comparing the RS I ground to a new loop and it looked like they had the same hook. I got a chance today to try the ground chain in pretty dry peice of wood and it seemed like it cut well. So I guess I was wrong about it not having enough hook.
Ok, here is two problems I have right now. How do you solve them/what do you do about them? Problem 1: Chain looks like it hit something at some point, most cutters are ok and sharp, but a few of the cutters are like pictured, almost straight across. Do you grind the hell out of it to get it back to the correct angle? Just sharpen those few cutters normally and leave the top straight across until you sharpen enough times to fix it (essentially grinding it back 1/8" or so...) OR??? Problem 2: I have a chain that I love, cuts great! Don't ask me why, but for some reason this chain has always treated me good, and I can't say I have treated it good! But it's starting to get real long hooks. See the picture... I've sharpened it so many times with my dremel, that it is getting rounded below the top of the cutter, and the top of the cutter is protruding forward. It is super sharp, and cuts great. But do I leave it? Do I file off the hook and then re-sharpen... What do you do with this? I'm sure a grinder would solve this problem since it comes straight down into the cutter and would grind this point off. Maybe I should just bite the bullet and buy a grinder? Cheap but GOOD grinder links please!!
Wow that first one is rocked hard. If its just a few I would just hit with a file and leave it. The other chain looks like your file is too small or your sharpening and way too steep an angle!!! Something is majorly wrong there and should not look like that
Problem 1: just file the few rocked out ones back til they are in good shape. No need to file them all to that length. Problem 2: Your file is too low.
That's what I thought on #1. I knew I didn't have to file them ALL back that far, but the question is/was do I need to file the "rocked" ones all the way back... I guess the answer is yes. #2, Yes I assume that, but how do you correct that? The file, dremel... anything I use on that particular chain seems to go deeper and deeper .... ? I've never had that problem on another chain...
I have never had a chain that looked like that when I used a round file by hand. Now I grind with a grinder so it obviously does not look like that. If your dremel thing makes it look like that get a hand file to correct it or get someone with a grinder to whack it back true for you
Just that chain! None of my other chains look anything like that! Have no idea why? Maybe because that is a LP chain?
