Here on the Christmas tree farm we needed a way fast and easy to sharpen
our chainsaws out in the field. The best thing we found was a 12 volt Dremel.
E-bay has them. We would also buy the DIAMOND CHAINSAW SHARPENER BURR Stones.

Love, love, love mine! Somedays wonder why it took two years for me to purchase.
Fall 2013 purchased Stihl MS 660 and an Alaskan 36" mill, am happy with the setup, hobbyist not a volume producer, have milled oak, hickory, yellow pine, and power poles.

I have this one (12V) and the original Granberg Jig (manual) 106b I believe it is called.  I think they are very well made and are of higher quality than the Oregon ones you find at most hardware stores.  They are a bit pricier than  the Oregon ones as well.  Once you get the adjustments right they work quite well.  If you get the 12V model remember they rely on the clips to attach to a battery so you may want to consider also picking up a cheap converter to slide it into a 12V DC plug (cigarette lighter) which is found in /on many vehicles and atv's.  I believe I picked one up for less than $5 at a local NAPA.  Since I am strickly a firewood cutter, I haven't found the need to use this as much as I anticipated and I find myself using more the 2/1 sharpening system from STIHL especially in the woods.  Holmen Tree put me on to them and Since I have .325 and 3/8" pitch chains to sharpen, I purchased one for each.  My local stihl dealer nocked $10 off the total price when I offered to purchase two.  So I now have a medley of sharping systems at my disposal which I find the whole process very interesting.  I'm also the kind of person that delves into the craft side of things moreso than perhaps a more pragmatic person might.  One other note with the Granberg 12V, remember to get the cooling crayons with the stone grinders you to keep them cool when grinding/sharpening. They are on the Granberg site for purchase as well.  I think you will be in the game for $100 bucks or so. I am not an expert by any means but these have been my personal experiences so far.

Thanks for the reply.

I too am only a firewood cutter so am not doing it regularly enough to get experienced with sharpening myself.  It seems this would make things easier and provide a much more consistent job.  It will be time saving over the long haul.  Last time I sharpened I thought I did well but just made dust instead of good cuts.

Think I'll pick it up.

You'll like it if you get one. Mines a 1012 I believe. I hand file till it seems pointless and then go with the Granberg. I have a Harbor Freight grinder I use to hog the cutters back if I really bugger the chain but the Granberg will sharpen it back to match a new chain and the Harbor freight won't as well. Use the coolant stick. Goes fast after a few minutes of use. I'm not one of the boys here but I have one and use it alot...Regards Walt

     Howdy,
   I have some stones for the Dremel, and other handheld grinders. I'm looking for people to check them out, and see what they think about them. As far as I know, nobody has killed one yet. I have them in 5/32, 3/16, and 7/32 in both coarse, and fine grit.
   The fine ones work well for normal grinding but, if you rock your chain, or your converting standard chain to ripping chain the coarse is quicker.
   First ten people to get back to me with a mailing address can have 1 stone of their choosing for free to evaluate. I would guess that a message on here would be the best but, however you want to contact me is fine.
Regards

Nice offer.  Are the stones for the Dremmel or Grandberg?

     Howdy,
   Yes, I had them made with a 1/8" threaded shaft. So, they'll fit any of the screw-in types, or Dremels with 1/8" collets. These things work really well. I tried some crazy things to fail one. With this one I had ground some new teeth clean off of 27 chain with no noticeable degradation. I finally started in on some files. Now bear in mind in this photo, I kept the file on one place on the stone the best I could. I would say that these will work well for different jobs as long as the metal is hard. Otherwise they will load up.

Thanks guys.  I did order one.  I'll be doing a lot of cutting in a couple weeks so I'll put it to the test.

In looking at the instructional videos, how do you know where to set the gadget on/above the chain?  Does it rest on the chain?

Thanks

Did you see this video from Grandberg? It should be a good starting point for you.  https://www.youtube.com/watch?v=IlosP6cPqhE

Thanks.

I have watched several videos but non talked about how to actually mount it, is it set on the chain, or address any angles of the mounting.

I used a dremel and a then a granberg and they both work ok when used properly as with most chain sharpening methods BUT I prefer the Timberline system head and shoulders above the others. Take a bit more time than electric but less time than by hand. I have not been able to achieve the same consistant results with any other system so far. New chain isnt as sharp as a timberline sharpener gets your chain.

No, it sets "over the chain" on the bar.  It has bolts that tighten onto the bar but allow you to move the chain forward to get to each cutter.  The "jig" part of the granberg has the appropriate angles marked on it if your particular chain type requires a 20, 25, 30 or 35 degree angle.  The jig provides from 0 to 35degrees if my memory serves me correctly.  The top dial provides for the up and down movements of the grinder stone to your chain cutter, the tension dial on the front adjusts for the lateral movement of the grinder stone to your cutter.  As the cutter tooth wears down from use and sharpening, this adjustment becomes more relevant in my experience.  It is something you have to play with.  I used other jig type devices to get an idea of the depth and other settings required for the granberg.

Thanks for the reply.
It just looks like it is possible to get it unaligned with the front or back tipped too high and change the angle of the cut.

I know what you mean but you can do that with probably most any system if you think about it.

I used it for the first time this weekend.  I think I've got it figured out.  Was able to sharpen a chain that's still going strong after a lot of work.

There's a bit of a learning curve.  And a bit of idiot curve-like not putting it in the back position and turning it on while resting on the chain!  Scared the crap out of me.  And scraping up the top of the brace, and grinding the chain instead of the tooth.  Once I got past stupid, it seemed to work well.  I had to re-adjust it when changing to the other direction.  Not sure what I did there.


I got a 12 volt converter and it works great with the machine.  It only had a 2 amp fuse so I had to up that--after the first blew.

I'd like to try it again but the chain is still doing its thing!

Glad its working out for you.  You really can't hurt anything and you're making progress.  There are other youtube videos that can help you with the grandburg too.

I've got the "Dremel" stones and what I use them for is repairing a chain if it discovers metal in a piece of wood or takes a notion to cut a rock in two .It happens .

Got to use it for a second time.  Worked well, the saw spewed out nice big chips.
It will be a time saver, and a money saver over the years.

I have had mine Granberg sharpener for around a year and use it mainly to sharpen my 36" rip chains for when using my Alaskan Mill.
The rip chain is a little more demanding if you want the best performance both regarding angels but especially tooth lengths. It also comes in handy when I got a couple of 36", 25" 15" chains to sharpen at the same time after a couple of days in the forest and they need to be put into the right specs after they have been hand filed.
