is there metal hanging out off the top plate?

Yes, I file inside out and that's the chrome that hasn't broken off completely. I just drag a small piece of wood over the edge when I'm finished and it flakes off.

If you go out side in it leaves a better finish but I just find it more natural to do it this way

you got it to make a flag with a file, thats impressive

Hopefully this might help someone when starting out with square.

The first pic is the side plate when filed with a Pferd 1250 DKT 175 hexagonal file.

Second is with a Vallorbe hexagonal file.

Both are the same design but have a different overall diameter. The Pferd is smaller overall but has a larger flat section that forms the side plate angle. The Pferd fits better in more chains and has a less aggressive cut than the Vallorbe.

The finished results with both are less photogenic than a double bevel file, it's just not as pretty but I think they are more effective.

Learning to use one is a up hill struggle. If your starting out use a double bevel at first.

Sharpened on my Silvey RSII. Touch of a beak but it sure does cut nice. Won’t stay real sharp for very long but good enough for who it’s for.

This tooth is done with a Vallorbe single bevel file. Much like the more common double but the side of the file only has "/ \" compared to the
"< >" Side profile.

These types of file shape the side plate much further down compared to the triangle / hexagonal / 3 square filed, or what ever they are called now.

Last lot is a few new links of Stihl 36RSLF for reference if you want to copy the original shape.

when i get a tiny beak like that i run it too....i have lots of chain when it dulls i just change it.

that should be pretty good. it has a nice chisel on the top plate. i square my top plate angle up more so it cuts smoother. from that angel in the photo the side plate looks pretty good too

this is my current grind.

Have you guys ever seen this video from Vallorbe?

Around the 1:50 mark they are leaving a beak and the kept the top plate angle at around 25 degrees.

I'm guessing a chain like this will dull rapidly but I'm all for trying new things so I'm giving it a go.

Feels really weird deliberately going low.

im sure that will dull super fast. there is no corner support with that much beak. the corner side of that cutter will get worn out in one or two cuts i bet.

Thas my best guess as well but I have some spare time and a chain so I'll try it for my self and see what happens. Part of me thinks it might work based off the amount of hook some people get away with on some round file chains.

Best I can measure this is around 50-55 of side plate angle. It's difficult because it's so small it hard to get a good reading on

 

[pbillyi69]

i tried for quite a while to measure the inside angles of a square cutter. getting something in there to take actual measurements is not possible with the tools i have. i tried a digital app and was able to get some approximations. but my smallest hand tools gave me the best numbers. however its really hard to get the correct numbers because they are based off the drive link or the the bottom of the cutter which is hard to use as a guide for the actual angles.

 

[Squish9]

Ok I just invented Stihl Hexa chain but with a 30 degrees top plate and a 50 degree top plate cutting angle. No idea if it works but I'll find out.

It was a weird experience trying to make that happen

if you square grind some of the small pico chains you get that profile due to its shape design
