Pictures from your chain sharpening.

And if you breath out on a filing stroke you are likely to snap the file they are that thin.

How do you guys set the depth gauges on them one-fiddy chains?

 

My angle grinder is making a bloody mess of them.

Fair enough. The gauge tool I gave is for standard 1/4" but it doesn't fit. It's so sensitive though that I'd worry about taking off too much with a file.

Here's today's effort.

Starting to like sharpening again.

 

It wouldn't hurt to also clean out your gutters/gullets. It's one of the first things you do on a race chain. Imagine the wood chip as the cutter carves into it. It curls down into that gullet. If there is a rise in the gullet, there will be some resistance as well as less room for the wood chip. You want as much room in that gullet as possible. It will also allow you to run lower rakers(assuming the wood and saw allow for it as well). That combo alone makes a big difference in speed of the cut. You can then also remove some of the sharp angles and weight from the rear of the cutter on a work chain to make even more difference without sacrificing reliability. This what I have done on the chain below(sorry, can't find my side view pic):

 

 

And here is how that exact chain cuts, freshly sharpened, with low rakers and a saw ported to within an inch of it's life:

Great info , thanks.

This prolly shows more of a difference. Though this saw is ported, it is not the beast in the previous vid. It is my trail clearing saw for the timber cruising work I did in Washington State. The rakers are silly low(like .045" as most of the trails will have Douglas Fir fallen on them), the wood is lodgepole pine(hard, as pine goes), the gullets are carved out to hell, and the chain is razor sharp with the same treatment as the previous pic, but even bigger gutters. It's also a standard 3/8 chain(as in NOT low pro) on a 16" bar on a 44cc saw:

Can't wish for any better. Spot on i would say.

Thanks, cuts nice anyway.

Raining here today so I'm a man on a mission in the workshop.
