i already tryed searching for this but cant seem to find it(i get alot of off topic topics like engine rpms) but where can i find a rpm controller for an electric die grinder, i mean like how to build one

 

Search on threads that talk about porting heads.

Also look in the tech article about porting heads linked from the thirdgen.org homepage. It might be discussed there (don't recall off the top of my head).

 

its in the porting head porting section. but if you cant finde it. go to your local hardware store and buy a dimmer switch, (for celing fan or lights) single gang box, two wire nuts and short extension cord. cut the cord in half. run the hot wire (black) through switch and tie the white ones togher then the green ones. got it ?
