A timelapse film of some chainsaw chain maintenance.

What exactly am I doing here? First, sharpening and checking each chisel and the cutting guides. Because there were some issues with wandering cuts related to wrong angles or chisel spacing, I'm also using a shifting spanner as a gauge to check that each chisel is a consistent size.

It's not a how to or instruction or advice, just a fun little film showing an attempt at problem solving with a chainsaw. Honestly if you're chainsawing a lot or a little just buy one of those new files that does the chisel sharpen and guide filing in one hit, they're great!
