roller file guide

[victorytea]

I also read the archives and have some questions left.
I just got the Husqvarna roller file guide for my 346xp. I have no idea how to use it. The rollers are for the file-correct? What are the round holes (slightly bigger than the file) for. If anyone would take the time to explain ( I know it will be difficult) how to use this sharpening aid, I will greatly appreciate it.

Hi Paul, I`m going to attach a photo I just pilfered from Kevin. He had posted it on another site in regard to a similar question, hope it helps you or someone else.

Jokers-

Thanks from someone else! That pic is great, I just bought one of these and was trying to figure it out!!! I hope it will work on my RS chain!
The quest continues, thanks for your help.

Hi Drew, glad that you appreciate Kevin`s pic(although it does look vaguely familiar, maybe from a brochure).

You will find that this guide causes you to use a smaller diameter file a little sooner than pure freehand but it is no big deal. Besides, file diameter is often a personal choice depending how you want your tooth to look and function.

Thanks guys!

Tony-
You still have access to the "old style" metal ones for a 3/8" pitch?
I would be interested if they are still avail.

Thanks very much to all-

Tony-

I appologize for the above post as I had neglected to remember where you are at in your personal life right now.
My sympathies to you and your family.
Dont worry about some stupid roller guide right now.
Get your things in order and we'll figure it out at a later date, if at all.

Respectfully-

Drew

Drew, the guide will work quite nicely on Stihl RS chain, but it needs to be modified to match the top plate angle which is different on the German product as well as for the slightly stretched pitch.&nbsp; See the thread "<a href="http://www.arboristsite.com/showthread.php?threadid=8551">Tach readings</a>" from this past March for further detail.

Hmmm..... slightly stretched pitch. I wonder if Stihl sprockets are made to a different pitch than Oregon or GB to accomodate this or if it`s insignificant?

Glen-

Thanks for posting the link to the roller guide discussion.
So if I understand that correctly, you widened the front notch a bit to fit over the drive links, and essentially raised the entire apparatus up approx. 1/16" on top of the chain?

I didnt have a whole lot of time to take a good hard look at it last night, but did notice that from time to time as I repositioned the guide on the next segment of chain that it was a touch tight, but still worked. I did look at the relationship of the top of the file to the top of the top plate, and noticed how it was slightly above the top oc the cutter. You had mentioned in a previous thread that the file should be approx. 1/5 of the way above the top plate.
I hope I didnt misquote you, if so my appoligies.

So if I did nothing to raise the guide up a 1/16" when sitting on the chain, what happens? I get to much hook, and dont stay sharp as long?
I will look this weekend when I have more time, and try out the zip tie idea as well. I have to go register for the wedding this weekend

Thanks again-

Drew

<b>Russ:</b>&nbsp; They pre-stretch their chain which must be the reason it doesn't need quite the immediate attention Oregon's does.&nbsp; It's not such a significant amount, so far as I can tell, where it messes with the drive sprocket.&nbsp; I guess the result is a more consistent interface with the sprocket(s) throughout the life of the chain.&nbsp; The thing I'd noticed with the roller guide might as easily happen with Oregon chain should a new guide be used on an old chain.&nbsp; There's also the possibility that the rivet heads are somewhat larger in diameter on the Stihl chain, or that there's a little more meat on the sideplates in front of and behind the rivets.&nbsp; (I forget just now exactly how the guide interfaces with the chain.)

<b>Drew:</b>&nbsp; As I recall, the front notch in the guide is the proper depth, but the Stihl R<i>x</i> series chain has the top plate recede less rapidly than the Oregon chain for which the guides were designed (it may be wrong as well for other models of Oregon chain).&nbsp; The result is that by the time you get back to the witness marks on the tooth, the rollers are too low on the Stihl chain, and there is way too much hook produced (as well too thin an edge across the whole top plate).&nbsp; By raising the tail of the guide the rate of decline can be matched to the cutter profile.&nbsp; I confess that I noticed the phenomenon by checking the guide on both new and old chains, where it was immediately evident there would be a problem.

When the guide is pressed firmly down onto the chain, if the pitch is just a little too tight it <i>will</i> raise one or both of the front or rear of the cutter.&nbsp; Great care can be used to work around that variability, but it's best to eliminate it from the outset.

The need for apologies around here is rare, Drew.&nbsp; We're mostly big boys (some aren't boys and some aren't big).&nbsp; About the only thing that really offends me is when I'm called a ******** in a roundabout fashion by changing the vowel in my login name.&nbsp; The very clever person that originally did it no longer does so since I requested it not be done, but there is another here who seems to have a severe shoulder-chip and rarely misses a chance at being purposely offensive.&nbsp; It's really a shame because he's obviously intelligent and otherwise has a lot to offer.
