I file vertical so its a lot easier to see and control angles and files position in tooth. There is no limit to how good it can get. If you are content in what you have then you stop learning and develop a finer skill. Most pro's I have here can't file very well and I do it for them. Same go for the machine operators.
Chains are best the second half ast they have better saw dust space. Keep riders high about 0,5mm you have a chance to get chain to last a bit longer.
File often. As soon as you notice you lost a bit cutting speed you file. Always stay sharp. If you wait and need more than two, three strokes you get behind the tempered zone of cutter and loose durability.
Low rider is often low as compensation of a dull tooth. Its not good and increase wear, risks, vibrations, fuel costs, efficiency and actually cut slower if you time it.
Corner! Thats were the cutting start and the shape of it will decide result. Even if its razor sharp the shape will decide durance. More beek, less runtime.
I have them more.
Keep file clean. One stroke, turn file half a turn so you don't push crap in file, file tooth, wipe and repete. No need for bruches or washing constantlt then. But when file is dirty, you wash it. When it gets dull dip it in apple cider vinegar and was it again. It eats of the burr on the files cutters. I have over 200 filings on my best file so far. Vibrations dull files so keep it steady, slow and let it cut as it should. Its a cutting tool, not grinding tool. Vertical you have better control and sight. Its closer to you and as your arm move more natural it won't get that bow movement you get if you are over chain when filing. Fix tooth so it is still with two fingers.
Look like a bit harder wood you cut. I would have less angle, around 20-25 degrees, you look closer to 35 degrees.
Your dust look broken rather than small. Usually this happen when riders are too low for wood to curl up nicely in cutter.
