    Thats awesome man, I know some of my other engines I have on youtube would be ripped apart from my dad's drill.

    (posted on step three) you can put another grey spacer on the other side of the blue rod for the first pic, either that or have the grey connector bump up against the yellow rod on the flywheel side of the crankshaft

    ah, okay then, you don't seem to need me, either way, I like the engine

    interesting design, it's an okay design, you may want to add some pistons to it, but as an experiment it does nicely, build on it and I'm sure that you'll have a good engine there.

    nice one!

    Oh wat does it do??? It can produce power when hooked up to a drill for one. It can also explode if redlined for too long!!!
