ROUND Grinders only

[jakethesnake]

Sometimes I let a tooth get half ass sharpened if it s a random short tooth usually won't notice it cutting then when u grind it again they'll "true" up next time sometimes when I file I don't get them 100 percent perfect I find out when I grind them later but like I say the grinder touches just slightly I let it go

Why am i not getting enough hook? The angles are 55/25/10

Looks like semi chisel chain.
What size chain is that? .325 or 3/8?
- 1/8 wheel for picco and .325 chain.
- 3/16 wheel for 3/8 and .404 chain.
When I do semi chisel I use these angles. 55/30/0. Also looks like you need to go a bit deeper into the tooth with the wheel.

Yes semi chisel 3/8" Oregon DPX

3/16 wheel

Where the shine stops is how deep the wheel went

I always find that semi chisel never really has much hook. I believe it's because of the design of the cutter. This is a different size and brand of chain but you can see how my cutters look. This chain is due to be touched up but you can see the shape.
Sharpened at 55/30/0 with 1/8 CBN wheel.

I guess im just used to having more control with a file

 

[jakethesnake]

Adjust on her a lol more that's not enough hook I'll agree

 

[KenJax Tree]

I went plenty deep enough so i guess 50° instead of 55°

This is the first loop i've ever had of DXP so maybe it its what it is

 

[jakethesnake]

Kenjax tweet that grinder you know what file work should look like make that tool do what you want it to I don't think that cutter will digg in it's gonna try to skip over the wood

 

[jakethesnake]

You are deep enough

 

[KenJax Tree]

I'll play around with 50° tomorrow and if that do fix it i'll get in there with a 3/16" file and hook it

I've come to a conclusion...... Old habits die hard...i like my hand filed chain[emoji52]

Don't give up yet. You just have to keep playing with it. Eventually you will figure out what works for you. Every grinder is slightly different.

Don't get discouraged, you can do it

Any forum member that live nearby? Maybe someone you could get together with that could give you a few pointers?

I figured that you were heading in this direction. If I was closer, I would come by and give you a few pointers that would improve your opinion of grinding, even if I could not change it completely.

Since I am not, I will make you an offer: send me a length of used, hand-filed chain that you are happy with, and a piece of identical chain (brand, size, type) that needs sharpening (do not even need to be full loops), cover postage, and I will send you back my best ground version, along with any information on angles / settings / techniques used, so that you can grind them the same.

Send me full loops, and you can do some side-by-side cutting as well.

Beat me by a few keystrokes!

 

[KenJax Tree]

Thanks guys but i'm not giving up just yet i know it takes lots of practice and i'll keep playing around. Its just hard changing methods after so many years and im not sure i could grind a chain like i hand file one.

I just don't see the grinder being my primary way of sharpening chain[emoji2]

How you dress the wheel has a direct effect on how the side of the cutter turns out too. KenJax, if you have been hand filing work chains up to this point, and after each day have multiple chains to grind you will start to love a chain grinder very fast. As Philbert mentions you know what a cutter should look like, now its just a matter of learning how to achieve this with your new tool.

I have gotten pretty good at round grinding and I am faster at it. I recently got a saw in from a saw mill owner that he files. Reminded me filed always feels sharper... but at the cost of speed. Ground chains are an art like filing...and they can cut real well but it takes time and light passes with a clean stone. I personally right now like my stone better than my CBN.

 

[jake wells]

here is my filing work and can anyone tell me what type of chain it is i know it is 3/8 0.50 chain and is stamped SW

 

[Philbert]

I think that 'SW' chain is Sandvik Windsor. They were each a separate brand as well, but I believe that they were each absorbed into the Blount / Oregon family.

". . . Blount International Inc. signed a definitive agreement to purchase the assets of Windsor Forestry Tools Inc., located in Milan, Tenn. Windsor, which posted sales of approximately $17 million for the 12 months ended June 30, 2000, manufactures cutting chain and guide bars for chain saws and commercial timber harvesting equipment. The business includes a modern, 60,000-square-foot manufacturing facility and will become part of Blount's Outdoor Products Group. The deal is expected to close within a month.

Windsor has been manufacturing cutting chain products since 1948. In 1986, Windsor Machine Corp. was acquired by Sandvik AB of Sweden. In 1999, Windsor was acquired by Snap-on Inc. as part of the Sandvik Saw and Tool Division. With products sold in more than 50 countries, more than 75 percent of Windsor's sales are outside of the United States. . . "
