need help with big script

[LoneWolf]

Hi, i need help with a big script. I decided i wanted to make my 5th map unique so i decided that:

I wanted there to be an area like the sewers where you need to move the handles (lever machine) to slow down the spinning wheel(cant find it right in level editor so i have no idea what its called...) i then want it to slow down to a stop. No pipe needed. But if its neccessary then make a pipe work to stop it too.

Tell me if your interested in helping thanks.
