Chainsaw grinder questions, tips, tricks, and pics!!!!

[chipper1]

Well guys I am waiting on parts to arrive for my saw rebuilds, so I got some time with the grinder yesterday....I ground my dad's chains which are all the .325 RM semi-chisel.....well after I got his chains done I ground a .325 18" RS full-chisel chain that I acquired....

So anyway I tried something just a little different in this chisel chain......I used my "regular" settings which are 30--55--0(on Stihl chain)..... what I did different was grind a little deeper into the tooth, which creates a little more hook or beak...I don't think it is to aggressive, but I haven't cut with it yet.... I also used the stone wheel on the RS(chisel) chain....I used the 1/8 wheel on all these .325 chains.....

The first 2-pics are the RS chain.....the last 3-pics are RM(semi-chisel) chains.....comments, questions, concerns all very much appreciated LOL!!!!!!

My "comment" would be that if someone is going to run a .325 chain with that much extra metal(those things are very heavy) on it you might as run 3/8 and get the benefits of having more metal on the cutter instead of them giant bumpers. If the depth of cut is not set by them I "fold the chain to gain access to them and cut the largest portion of the tip off(it only takes about 4-5 min one time and some of the added weight is gone0, unless you are trying to keep him on the safety plan. They can also make it tough to do a plunge/bore cut which I use nearly every time I cut, unless I'm cutting cookies .

Yes sir. Two. And go thru the belly button. Be back grinding in no time.
If they cut ya. You down long time.

So we're both of yours the "lower" kind.....do they cut you for that kind....

Can you lift like you used to, once you heal up

Oh yeah, sharper chains lead to less hernias .

Make sure they go through the belly button. Recovery will be quick.

Ya I was actually goin to put this in the post.....I did not do the rakers yet, or grind off the safety humps.......I always cut them off of chains I get in saws I buy.....


I use an angle grinde, it's worked great each time!!!

Yep .

So what do you guys think about the Oregon Vangaurd chain.....I got 3-20" loops in a batch of saws i bought awhile back....I ground the cutters last night, but I have to ground the humped over raker when I get home.....my plan is to just get them at the same height as a regular raker, and see how she cuts.....

I can't stand to see a chain wasted so I am goin to get them cutting good one way or another!!!!!!

I file those rakers from the front rather than on top.

How are securing or holding chain when grinding down humps?

Hey good to hear from you!!!!


Anyway I usually mount the chain on an old bar on a saw....I have also just wore a thick glove and ground them down.... I know, sounds dangerous, but I do it ALOT and have never had an issue!!!!!

 

[Khntr85]

So I played with the Oregon Vangaurd chain...the results, a chain that ABSOLUTELY rips!!!!!

I ground it at 55-25-10, and I just ground the rakers to were my eye thought they looked right....just glad to make 3--20" 3/8 loops ready to cut agian!!!!


Anyway here are the pics

Here is Vangaurd with rakers ground

Nope, my Foley Belsaw is much smaller...

Ya I went just a touch low, the first few cuts in a walnut log chattered just a bit lol.....but wow does this chain cut good....I sure am glad that I got these 3-loops of the vanguard back into shape...

I tell ya if I didn't have the grinder, these chains would have been a total pain to get right....basically the chains had been sharpened a few times, but the rakers were never touched....so there was a lot of material that had to be taken off of the rakers......taking all that material off by hand with a flat file would have worn out a few flat files, and my shoulder lol....luckily with the grinder it was all an easy fix!!!!

Let me try pics of my Foley-Belsaw again.

I-n-t-e-r-e-s-t-i-n-g!

Looks like a fixed (60°?) angle grind?

[Cutforfun]

It looks like a 399, I have one I use for rakers.

I dunno what degree that clamp is,,been a dozen years since going over the op. manual.

 

[Philbert]

Now THAT one looks like it could be converted to square grind with a little ingenuity.

I use the larger Oregon wheels once they are worn down, had to make a bushing since the arbor is a different size. You can see in the pick I run the chain backwards when doing the rakers
