Nice video, although I highly suspect that you don't have the permission to use those musics in the video, so it is a copyright infringement
And there is a certain *cough* "reputation" *cough* towards YouCrap, so next time use PhotoBucket or similar
GENERAL ADVICE! As I have seen that in many videos nobody brings the issue up front, I'd like to share a little warning on grinding metals: If you suspect or you know that the grinder has been used to grind aluminium in the past, please clean it up outside and inside and also the workspace. If aluminium has been grinded and you go and grind your hacksaw blades or anything ferrous, there is a very high risk of thermite reaction. Thermite reaction happens for example between finely grinded aluminium and ferrous oxide metal (as in rust). Thermite is a compound that ignited (from a grindering sparks for example) burns a few thousands of degrees in temperature and melts any metal in contact with it!
From Google I once found an article from a newspaper, that told of an accident like this. There was a son who had grinded twelve aluminium pop rivets and his dad, unaware of that, started to grind something ferrous metal. Couple of minutes after starting there was a bright flash and a half a meter wide fireball/sparkshower engaged. The father had eye protection, so his eyes were saved but arms, T-shirt, hair, moustache, and face suffered from burns.
So, remember your protection always and clean out your equipment and workspace and remember that nasty thermite runaway reaction while grinding
