Chain sharpening tutorial.

Could be just fine then
The hook will help it self feed ............ how was it self feeding ?

 

Yea but that thing looks almost cartoonish. And like it will just fold over?

 

I can straighten that out on the CBN real quickly if you want Sir.

It also looks like your stone has gotten smaller on your dremel, or you are grinding too low for that stone. A couple of solutions for you are to use a larger diameter stone, or grind higher in the tooth and make a second effort to clean the gullets.

The cutters that look to have been rocked could have been rocked, or the bark on your wood could have removed the rather large and thin hooked top plate due to it not being strong enough, as it is definately thin.

 

It probably did fold over and break on Machria's chain, but I was quoting 94BULLITT's post

 

#2 It may be a little hard to correct freehand. Your dremel may be easier to correct it with than a file. You just need to hold it higher. What size stone are you using?

I think clem was right, the other weren't rocked. They were breaking off from having to much off a hook. I thought at first it was 2 different chains.

 

I tried it on a piece that is maybe 7" in a diameter. After it got about 1/3 of the way in it pulled itself through. The tree was pretty dry too.

 

It will probably have just the right attitude for a green tree then !

 

Mopar I was thinking it was two chains? If it is indeed the same chain I can deffinitly see why the teeth broke off

 

Same chain... and I'm using a 5/32 file/bit on that 3/8LP chain. It does seem like it's too small for it, is that the problem? Should I step up in file size on it?

 

5/32 is the right size.

 

I think it will be fine for dead stuff. I tried the untouched loop of RS on the same piece and I could not tell that it cut any different. I guess a chain has to have so many cutters in the wood for it to self feed right?

 

Looks like your just running to low. In your pics I see that your grinding the tie straps.

 

If 5/32 is the right size, like mopar or someone pointed out it could be worn down and therefore too small now.

 

I think you mean the bit, right? If so, no that's not the problem... I have lots of bits and change often/throw away the used ones... I use the diamond bits which last much longer...

 

Just step up a file size and sharpen till the material is rolling along the cutting edge.
Do that for the next couple sharpenings..
Avoid any down pressure on the file, as there is no tooth there to support it.

 

Hmm. Yea thats what I meant. Well never mind then?

 

Thanks guys... mopar gave me a Timberline sharpener to try out, and he suggested I try that on it to see of it will fix it. I'll see what happends, maybe that jig will hold the bit in the right place with no down pressure and fix...

 

These keep a file up off the straps also.

 

That's interesting looking for hand filing .... what is it?

Can the height be adjusted?

 

Husky roller guide..
less hook = bigger file
more hook = smaller file

They are pitch specific. I.E. 3/8 or .325
