Hello - I am new to this board and have been lurking for the last several days. I sure could use some good recommendations on Sharpening Tools. I just recently purchased a Stihl File Guide and have been looking at the Granberg Bar Mounted File-N-Joint Rig. My buget does not allow for those expensive bench mounted grinders. Although I could buy those handheld electric grinders I have seen offered by both Oregon and Granberg, don't know if they are any good or not. I am asking for sound advice cause I do not want a collection of sharpening systems just gathering dust but want a setup that actually performs well as long as I do my part... Sorry for being long winded!

Welcome aboard Sawmeister! The Stihl file guide, if it is the one the file clamps into, is a good guide. If it is the proper one for your chain it is hard to mess it up. A friend of mine keeps one of those 12 volt grinders in his skidder in case he stones a chain real bad, but he always finishes up with a file. He says that the grinder is a little harder to control than a file when you are using it freehand. Any chain he does this to is relegated to topping and bucking, he puts on a new one for felling.

I just use a file and file handle and have good results. The Stihl brand chain has lines laser etched into the top and side of the cutter showing you the top angle and side hook shape. I just make my file follow those marks and it works pretty good. You really have to make sure you hold the file at the right "height", in other words, you are not pushing it down to far toward the bar or holding it too high to the sky. The Stihl file guide really helps alot with this.

There is one tool I use regularly, and it can fit in your shirt pocket. Husky sells a small flat piece of metal that you use to adjust your depth gauges with a flat file. You simply lay it on the tooth, and the depth gauge sticks up through a hole. You file the depth gauge flush with the filing gauge and you're done. It works better than the Stihl because you adjust every depth gauge for that tooth. The Stihl takes an average over several teeth. It still works OK until you have a tooth filed back more than it's neighbor.

Practice filing saws and you'll never want a grinder. They're nice, but it's hard to carry one in your back pocket in the woods. I kind of like filing because it gives me a break. If I've cut enough wood to need to file I need a rest too.

Frickman - Thanks for your reply. The Stihl File Guide that I bought for $16.95 sounds exactly what you are describing. It came with a nice pouch that included the Guide with a 7/32nds round file, a flat file for your rakers and a depth gauge the kind that you slide a long your chain. A friend of mine has one of those 12v Oregon Grinders he swears by but the fellow at the local saw shop told me that all you need is a file and a guide and you are set...

If you have a 7/32" file you better be filing .404" pitch chain. Some guys around here use 7/32" on 3/8" pitch chain, but it is really too big. 3/8" takes a 13/64" file at first and then a 3/16" when you get filed back on certain types of chain. What pitch of chain are you using SawMeister?

I'd like to hear more feedback on file sizes. Three of my saws use 3/8 pitch and I sharpen those with a 7/32. I tried a 13/64 at first but it seemed to small. Am I causing damage or faster wear to the cutters by using a 7/32? If I am is it to late to go to a 13/64? Does one file size or the other have an advantage when sharpening 3/8 chain?

I am using a 3/8 pitch. The file that came with the Stihl 3/8" File Guide is I believe a 7/32".

If you want a small lectric one then buy a granberg I love that little grinder it is the best thing to sharpen chains with I like it bettter then the dremel, oregon or the northstar brand. It is awesome the stones are worth spending the extra money on I usually can sharpen 7 or 8 chains before I need to change the stone.

SawMeister · « **Reply #7 on:** September 30, 2004, 08:02:02 pm »

DanManofStihl - Does the 12v Granberg Grinder come with a depth guide to take down the rakers? Thanks in advance...

Use the same depth gauge as you would for hand filing. I try to touch up my chains frequently so I don't have to spend a lot of time on the grinder. After 30 years, I still won't hand sharpen a rocked chain

i love my file-o-plate --->here's a link to one: http://onlinestore.forestindustry.com/cgi-bin/baileys/new0399?mv_session_id=awfdpeH5&product_sku=65986

it has a depth guage for the file, a raker gauge, an easy to follow guide for your angle, and a mesuring guage for links. they are available for 3/8 30 degree and 35 degree and .325 30 and 35 degree [i think]. they really work great as long as you don't have a lot of anti-vibe bumper rakers or that 72V chain with the funny rakers.

Hope this helps,

Yeah it has a guage to take down the rakers it takes a little time but it will do it. It is faster then hand doing it it really excells at sharpening the chains.

Someone mentioned the 72V chain, I really like it, but, it is very hard to properly take down the rakers as previously noted.

I use the Granberg guide that costs $24 and had to make some mods to mine to make it better since it is not sturdy enough in my use. Maybe I bear down on the file too hard ...
It is accurate enough and does a good job.

I tried the Dremel attachments and 12v stuff, not accurate enough to get repeatable performance, imo. Though the Dremel is good for a rocked chain or chain that has found a steel object inside a log.

PFERD Tool - Has anybody ever use this niftly gaget? Suppose to sharpen cutters and taken down rakers at the same time.

UrbanLogger · « **Reply #13 on:** October 03, 2004, 08:13:41 am »

I use a Pherd guide and love it--gets it all done in one step.

Also, since you flip the round file over in the handle to do each side, it gives me better control sharpening the rightside teeth (my weak side).

Timber_Framer · « **Reply #14 on:** October 03, 2004, 12:31:17 pm »

Do you have alink where I can find a Pherd guide?
I tried a google seach but came up with a lot of pages that had nothing to do with chainsaws.

Timberwerks,
For years Stihl recomended 7/32" files for 3/8" pitch chain. For the last while they have recomended 13/64". The 7/32" will work, but it does not put enough hook in the cutter. You may also end up cutting down into the rivets on the drive links. The best thing to do is follow the laser engraved lines on the top andd side of the cutter. If you follow them you'll be in good shape.

Just to add my 2 cents - I was about to ask about sharpening too

I've bought a hand file to sharpen and just had a chain sharpenened by a local shop. They used a grinder and most of the teeth came back blued on the tip.
I'm new to chainsaws so was thinking is this a problem with the metal in chains? - I only ask as I know this is a problem with my wood chisels.

I also got a jig with my mill, which you place a file in and lock the jig onto the bar, then adjust the file angle and other adjustments - a bit too complicated to understand yet, it only came with 7 pics for set-up

Any thoughts/comments or help would be great
