I don't believe the scribe thing is ever going to work well, but you'll  
see.

Those R/C motors are plenty powerful. A few hundred watts is not unusual  
for RC aircraft motors.
But the brushed motors don't last long.

Maybe you should look into building a brushless motor. Should be very easy  
with your machining skills.
I know someone making brushless motors for CNC and machining applications  
and selling them for big bucks...
