.325" square

[Wolverine]

So I decided to crank up the ol' file and give my sons .325 a go. Gotta say I'm not a fan Not much room in there to get goin'. I was on tie strap for a while till I got the clearance to finally get to the sweet spot. Go ahead and let me have it...

Won't be able to test it ot for a while due to sub arctic weather.

Hard to get forward lean on the smaller chain

Only 2 chains didnt have a forward lean in the 3/8LP chain build off that I remember off hand. Those 2 had to be pushed.

The Carlton I had was for a 20 inch bar. Just threw it up there for comparison purposes. Also I thought each contestant had a limit of one entry for work/race ea?

Currently In 66 DL I have (2) Stihl RS, (1)-Oregon LPX. I could order up a Carlton as well. It might be interesting to put the same square geometry / Raker clearances the on all three and let the chips fall where they may.

Try to keep the file on a steady plane as you move it into the cutter, especially on the last couple strokes. This will help to make a cleaner and smaller working corner, along with a more pronounced intersecting line under the cutter and through the point.
Also, try to blow the filing crud off the cutter a bit so the camera don't make optical illusions and misleading shadows.
Good pics of cutters can be a challenge.

My last pic, I'm hesitant to remove anymore tie strap. Do you get similar results?

I think you're fine on the tie strap. I haven't played with working angles so I can't help you there. With what I'm doing I'm not hitting the straps.

Try taking a round file and cleaning the gullets out real well before laying a double bevel file in there. It will help you keep from snagging the straps, which tend to throw off your angles a little..

On a race chain, I don't get the straps, but I do on a work chain.

No limit.

No limit.

Sure there is..

The limit of one's patience with the filing of .325 chain.

Angles held up just fine to my surprise. Was throw'n some bigchips near 5 inches long "crosscut"

Is it worth the headache to file 325 square?

 

[Mag Craft]

I just finished off my .325 chain today for the chain build off on chainsaw repair site. Cut4fun will be doing the cutting.
I did some testing with a Poulan 335 in some pine I had here. The chain is square ground.
