Simington / Silvey Square Chain Grinders Tips/Tricks/Secrets

[Miller Mod Saws]

Ok guys I'm used to machinist tools so I didn't have a protractor anymore and this was the closest I could find in town. I hacked it up so I could check to see where my dresser angles are for reference. Sorry no before hack pics. But you'll get the idea. Lol.

On a machinist protractor. Where you see 45 is labeled 90 deg. But that dosnt matter. I know the 45 is a 90 degree corner and this dresser sits at 30 deg on protractor so the dresser is at a 15 degree angle.

And the back dresser sits at 27.5 degree so it's at 17.5 deg. Again. This is not in relation to the chain. It just gives me a known point so hopefully when I find an chain I like I know where the dresser is set.

How's the cutter look?

Ok new stone on and dresser angles changed. I know from talking and reading here. After I test ground the first chain and compared it against a stock stihl square ground. My cutter side plate has a lot more lean forward and the tooth has less angle. Making a lot longer ground top plate. Hope that makes since. So here's what I changed for the first go.

Give me a bit. Remember I'm new to this. Setting up a new salmon stone now. Lol.

Be nice if they came pre-dressed.

 

[Miller Mod Saws]

Well I think I'm close on 2 of my 3 angles I wanna start with. This one I have no idea how to adjust. Back to reading. Front chain is a stock square ground stihl. Lol.

 

[Miller Mod Saws]

Ok. I'm at a loss. I have this angle matching the stock chain. That's it. Lol.

Somehow I need to give the tooth less angle this way. This is a ground tooth.

That's fine. I like 25° top plate unless my goal is durability over anything else. Then really semi chisel is a better choice. How much forward lean do you have compared to the rail holding the chain?

 

[Miller Mod Saws]

And make the face of the tooth more blunt. So the purple arrow needs rotated up. This is ground so where my grinder is sitting right now.

Top angle looks good to me Carl.

What is that stuff? Looks cool in the pix you posted...

That is Amsoil Saber at 40 to 1 ,Husqvarna xp oil looks the same mixed up also .

I like less angle there also ,there is a 7/16 size nut on the chain carriage ,loosten it and pull it away from the stone as much as you can and still grind and it will look like this .

Not sure which nut your talking. But I'm all ears. Lol.

The chain I just ground.
