i never said its not enough revs. please reread my post. it says not enough info on the motor he wants to use.
that hotwheels principle is what i was attempting to explain too.

KenWittlief has a good point. other than the whole coolness of a rod flying 30feet to go through a sheet of metal, why do you need it to move so much?
and how about having a spike on the flywheel itslef and move that flywheel closer to the sheetmetal. and then itll more rip the sheet than just puncture (well not necessarily i know)
