Square filing chains

Could you post another picture of it more from the front?

Aligning the corner is the biggest thing. You've done that. And the straight side is good. Don't worry about hitting the straps. If your filing on the bar or chain vice it's going to happen.

 

Back at it...

 

Good reference for cutter angles. Square Ground Chisel Angles

We're not trying to be hyper critical. If it is not the picture deceiving us and we are really seeing an inner top plate angle that is shallow then it will cut but, not stay sharp long. A shallower inner to plate angle will reveal less inner top plate cutter face in a pic. ( shaded black part). I'm seeing the inside corner between the red and black shading. If you can get the file to 40 degrees just hitting the strap it could put you down in the red area for the inside corner making for a more durable cutter.

 

You are on a roll and should finish up your chains in no time! I'll send mine over next week.

 

I'll get a picture tomorrow.

 

I think I have all of my angles right except for the outside top plate. I'm pretty sure it is more than the max of 20* madsens recommends.

I appreciate the help. I'll try to get another picture and go from there.

 

If I'm seeing it how it is I think it'll be durable just cut slooow. That sideplate has a lot of meat on it. The inner top plate angle has to be close to a durable angle with the roll of the file would have been at to make that outer top plate angle.

 

Do I have the roll of the file wrong? I am holding it so I have a 90* outside side plate angle.

 

Not for the other angles you have.

I still think from the picture you need more up/down angle & a smidge more to the back & adjust roll accordingly.

 

I'm so bad a describing things. I tell people don't make me tell you how... I'll show you. I'm sure somewhere in my previous couple posted I said something way off and reader's are going "What?".

 

I would love to see scaled up size of a square filed cutter out of wood with a protractor on every angle with pics.

 

Here is a picture from straight ahead.



After I took that picture I tried holding the file and taking a picture. I think I had filed too high. The lighting is crappy around the work bench. I have a clamp on light on the saw I can get the light on the cutter and file at the same time.

I really can't go any lower without hitting the tie strap. Now, if I did not have the file too high on that one and had it where it is supposed to be, it would have been flatter. The file needs to be aligned in the corner, so that is the fulcrum point. The only other thing that can be do is to file into the tie strap.




I have about a 30* outside top plate angle. Madsens recommends a max of 25*.

 

Angle the file more, its OK to whack the strap a little more
I find that a 25 degree top plate is too much
Look at the drawn line and aim for that

 

You did this one back on page 35 of this thread - looks good. If you can find that chain it would be a nice guide to get you back on those angles.

 

Nothing wrong with filing a bit on the strap. Don't get carried away with it. But it's not anything to stress about.

 

Firewood loop.

 

That might be too sharp. You better throw a blindfold on the wood so it does not see it coming!

 

That will cut good! Not grabby, last good. What species of wood do you mostly cut for firewood ?

 

It varies. I burn a lot of apple but my last hoard was primarily shagbark hickory and some white oak. Right now I’m burning walnut, ash, red oak and mulberry. You know the saying, variety is the spice of life.
