I was just wondering how many of you prefer using a 13/64's file over a 7/32 on 3/8' chain,I have been debating on whether or not to switch to 13/64??

later Rob..
 
I personally use 7/32 and get better results ,less grabbing?
but , not to draw from your survey stihl magnum, I have seen alot of sayers ,expierienced even use one size file for any chain
5/32 in particular, i do not , I have the oregon B&C manual
(recommend to begginer).

O.K. ..O.K. .. lol , I have to but i don't remember how hard it was to reconsile ,(almost did it again in a pinch last wk. ) any
advantages ? lower gullett
 
Well I also use 7/32 but I know a few people who use 13/64's and find that they like them better for some reason,so I guess the only thing to do is get a few files and try them out to see which one I like better...I was just wondering if there is a advantage to using a 13/64's compared to 7/32?

Rob,
I personaly use 7/32 untill i get about 3/4th the way back on the cutter then i switch to the 13/64.
I don't know if this is rite but my chain throw a lot of chips.
 
I like the 13/64 because so many times the file hangs on the rakers if it is too big. I tend to get buy with whatever file will lay down in there on new chain.(about 1/5th above the cutter) And many times that is not the file that the manufacturer recommends. But its not the manufacturer that has to do the filing, its the customer.

They could make the chain so the recommended file would lay right in there at the correct depth, but then there would be no reason for anyone to have to exercise their brain. We might only have to have 3 or 4 sizes of files instead of 6 or 8.

I'm glad i do mostly grinding at the shop.
 
I just ordered 144 new 7/32" files yesterday so I guess I use 7/32" files :D


I like them, lot less chance of putting a hook on it.
 
JimL,

I noticed that with my friends chains when he uses the 13/64's the chain seems to have alot more hook than with a 7/32.

Eric,

I guess as long as it keeps flingin' the chips thats all that matters....LOL.

Standard 3/8 chain

If you like to file your chain on the "hungry" side with lots of hook and lowered file handle, you will tend to file into the tie straps more with the 7/32 file than you would with a 3/16 file. As mentioned some new chains are hard to get into with the larger file especially if using a file guide. Filing with the smaller file will leave more metal in the bottom of the gullet and hamper chip removal somewhat unless you deepen this in a separate operation. You probably would need a stop watch though to see the difference.

Each chain model, no matter what pitch, has different cutter
dimensions [height, etc..], so speculation about file diameter
is a waste of time unless one specifes the make and model
of chain. Even so, I must eyeball the file with the chain to
sell the customer the correct file. The correct diameter file
is more critical with a file than with a grinder, as the top
angle is completed with the side of the grinder's stone wheel
and the gullet's angle is not as critical, but with a file, the top
angle is defined by the "correct" file diameter.
The rest of this thread is not for the faint at heart, as I am
evil incarnate!
I realize terminology might differ between us rednecks, so go
easy on me. I am quite sensitive.
 
i've been using 13/64 but have found that the 7/32 seems to work a little better for me
 
Lets see if I can do this here's a pic of my first saw?? Oopps I guess it's a little small this is back when I was 6 it's been a while LOL..

Later Rob..
 
Well atleast I can finally export some pics from my scanner that whole digital camera thing I can't do it.I'll just do it the old way 35mm and scan all my new pics...

How do you like my backhoe..
Later Rob..
 
I guess I'm gonna stick with the 7/32 for the time being maybe I'll try the 13/64's when the cutter gets smaller and see how it works then..

Here's my old man digging out the Cat back in 1984..

So you will start AND finish your threads?

Did not the possibility of different chain types/models even
adjust your thoughts/and/or/ conclusions? If you start threads
And answer them, it will be a long and useless winter. There are
several different cutters on the various 3/8 pitch chain. So 1
file fits them all?
Just stirring up trouble, as usual.

The differences in .325 chains is more evident. If just one of you
proclaims one size file fits "all" .325 chains, even brand new,
then I will contend you have no anchors in reality. 3/8 chain
is the same. There are many models of chain, and no one
can recommend the correct round file without knowing what
model chain was in question.
Each chain model/cutter height requires a different file size.
Not trying to fight, well maybe, a little.
But the endless river of false and/or useless info on this forum
is getting out of hand.
I stock at least 8 different sizes in files .
I try to keep the side plate angle at @ 60 degrees, top plate as
well . I drop 10 degrees for the chisel chain.
 
Start and Finish my own threads no I try not to but I only use one type of chains 72LG and after trying a 13/64 file on it today I find that it creates more hook than using the 7/32"...Sorry bout that Fish it won't happen again :(

Later Rob..
 
Fish, I have some chains here for which I know not the correct file size. You seem to indicate that if one doesn't have the box it came in to tell you what file size to use, it is hopeless to even attempt to arrive at a proper selection unless you personally cast your eye upon it! This would seem to result in a lot of lost time and expense of shipping back and forth to you. Fish, PLEASE try to help us out in the form of some rule of thumb we can use in the meantime until this is somehow resolved.

Anticipating your most immediate attention to this issue,

Frank
 
Sorry,
the beverage was flowing, I was PUI! Posting under the
influence.
But seriously, each chain model number, even from different
time periods, require a different file as the cutter height varies
with each chain, so I ask to see the chain. File diameter is
critical to get the angle correct, so I order boxes of files in
increments of 64's, and as the cutter is filed back, the diameter
of file should change.
As you look at the actual angle of the chisel, not from the top,
but from the side, should be @ %60, and any slight variation
of file diameter will alter this angle drastically.
With a grinder, this angle is made by the side of the stone/
wheel, so the only difference is in the depth of the "gullet".
I refuse to go into the theoretical physics of "chip travel", as
that is for other nimrods to explore, and I refuse to go there.
If one needs to know about the reality about what the chain
does and what happens to the chip of wood, just ask Art,
and listen.
But the best angles I have found, have been %60, on all of the
angles.
I have some old Windsor charts, which I based my work on,
which I can send anyone, if they ask.
I know ripping chain requires different angles, but I have none
of that around here.
 
Fish;
I expected my sarcasm to generate more of the same; you capitulate too easily. I am suspicious. What are you holding behind your back.

Seriously, although I mentioned standard 3/8 chain, you are very right about there being a wide variation needing different file sizes. With a bit of experience it is obvious what you need when you look at it and you also know how to compensate some if you have to use the wrong file size. I think a beginner can learn a lot more by looking at a bunch of classically missfiled teeth than at a perfect example. I have seen some filing that you would swear came from a sheltered workshop; what a powerful teaching aid it would have made!
