Any opinions on the Granberg electric chain sharpener?

The first two times went well, but...

The bushing that the arm slides thru on one side is off center.  Don't know if it has always been like that, just noticed it.

When I switch from one set of teeth to the opposite, I have to change the height of the cutting wheel or it will bottom out on the tooth.  So, I can't tell that I'm getting the same grind on both sides.  And it doesn't slide smoothly at all.

The last couple times certainly didn't do as well, not as sharp and didn't last long.

I'll take a pick and send it to granberg.

I think the pink stone's don't hold up very well I use Oregon instead . I use the free hand Granberg . When you run a cord an hour through the BT 6870 processer you want a quick sharpen .

I sent it  back and they called the day they got it to say they have it.  They called the next day to say they found a problem, will fix it and mail it back. 

It will be a few months before I can check it out again.

So, great service.  I assume it will work fine.

Ok well good luck and keep us posted.  Glad they are working with you on it.

Got a box back today with a new grinder.
The note said faulty shell.  Not sure what that means, but they stood behind it and sent a new in box grinder.

Good to hear.

I know a couple of guys that use the granberg including the local small engine dealer/shop. He sells husky gear and equipment.

They ALL say that Granberg has top notch performance and service and one guys system is at least 20 years old. He says they treat him like he bought it yesterday.

I like the job it does but just find the timber line a bit quicker in the field and for me I don't over grind with the timberline as easily.

They are both good sharpeners.

I recommend the precision granberg grinder
https://granberg.com/product/g1012xt-precision-grinder-12v/

You need the fixture to assure that your grinding is consistent in height and angle from one tooth to the next.  The problem with the free hand grinders or the dremel is that while they make make the tooth sharp, inconsistent height from one tooth to the next will cause problems in cutting.  It will make it seem like your chain is dull, or it will dive to the left or right. 

Get the precision grinder above that has the adjustable fixture and you won't regret it.  Granberg's videos stink on how to set it.  Wranglerstar on youtube did a far better job of explaining.

I too can vouch for the granberg as it sharpens very efficiently and quite fast. I have used many chainsaw sharpeners in the past but the Granberg is still one of my favorites for all types of saws. But it is not for everybody. Maybe you should check out these chainsaw sharpeners if gou want more variety. http://thereviewgurus.com/reviews/best-chainsaw-sharpener/

Can you use non-threaded grinding stones on the Grandberg G1012? Unsure what the collar is like to be able to use posts without a thread.

[ksks]

They are threaded.

[4lane]

So, it's impossible to use grinding stones with non-threaded posts?

[ksks]

Correct.
