God of War 1 rotating saws puzzle? Help Please :(

I'm stuck in the room full of rotating saws :cry:

There are 2 levers either side of the room, which open the metal bar gates. i'm not entirely sure about the sequence or timing in relation to the rotating cogs & sand bags. This is so frustrating :(

Someone please help :oops:

Thanks taste & matt - much appreciated :), finally progressed woohoo ;) :) :D

Some puzzles drove me insane espically the one with the saws.

puzzles and platforming was painful in GoW that's why I like 2 so much more.
