Chain filing - 1000 Frames per second

Very cool! I zoomed in a bunch and was checking out the individual metal shavings. Nice work. ~Dr. C.

Love the suuuuuper slo mo

Well Tinker, that’s what a sharp file should do, probably more.

1000 fps would be enough to film how the chain cuts depending on various parameters. Just 1000 fps was used by a researcher here about 10 years ago to study how a saw chain driven by an internal combustion (reciprocating) engine behaves. However, he reduced the engine speed to 6000 rpm, because 1000 fps is not that much when the engine speed exceeds 10000 rpm. You can, of course, rent cameras with large higher fps. I would like to use such a camera someday to film the differences (or rather confirm them) between a chainsaw with an electric motor and a combustion (reciprocating) engine. However, my curiosity is not high enough to justify the very high cost of renting such a camera.

@@elpolaco7654 I tried multiple times today and unfortunately it's just not enough. I would need to reduce the chain speed and feed pressure dramatically to be able to capture anything meaningful. I will try again if I can find a saw with a reduced chain speed but for now I'm out of ideas to try
