I'm guessing that is the predicament this guy found himself in. There are hundreds of different styles of drills, grinders, sanders, cutters out there, but all use either compressed air or you have to plug them in. Sure, there are battery powered tools, but they lack the punch this guy (man) wanted.
So with no air and no electricity, what do you do? You strap a nitromethane engine to it, duh.
This video, by johnnyq90, takes us down the fascinating path of not only using the aforementioned nitromethane die grinder, but shows the steps in the creation of the little monster. A lathe is his main too of choice, and he even shows us how the first few iterations failed. Not all things happen by magic and on the first try like the TV and internet wants you to believe. He (johnnyq90) has another, slightly longer, vid showing him strapping a nitromethane engine to a drill. I haven't watched that one yet....so I will now.
