Hello, normally I would hate asking for help, but I just can't seem to find a way out of here:

Spoiler below!

I'm at the place with the cogwheels, Rods and levers. I have the Blue and the Red Rod. I have all the cogwheels placed on the machine. I found a bucket. I can't go back, and I can't find a way to continue. I also have a Pipe and a Knife, but they don't seem useful at this moment. I've been in this place for over 40 minutes, trying to figure out a way to progress.

I hope someone is able to help me.
