OK I turned it 21 times (of the armature to make one full revolution of the wheels) ..........daniel

Thus, the gear ratio expected based upon the worm and gear train would be 8.33 + 2.45 = 10.78.

That is 8.33 x 2.45 = 20.41:1

WBC, you're probably right about the 11 tooth pinion;

9 tooth pinion would give 25:1

10 tooth pinion would be 22.5:1
