Very boring video.
That shows how long it actually takes to split 270mm long piece of 170mm thick rr-track.
Answers also question about "how many wheels it takes?", " Is it hard Job?" And If watched carefully, also gives some hints about how to.
Cutting happens in real time, only parts where i adjust camera etc are speed up.
Video is boring and lasts about 30min. Don't watch it If you have better things to do.
