can you give a more exact description of your drivetrain? What gear ratios do you have? What are you using to acheive these gear ratios? Is there any misalignment anywhere? Your explanation is a little confusing?

Oh and btw to answer your question about drills vs. chips, they both have their place. The drills are i believe slightly more powerful than the chips. The drills have a much higher free speed and a much lower torque output. The chips have much higher torque and much lower speed. The CIMs are much more reliable and durable than the drills.
