Armature timing gauge (ext. version)
This gauge is used to accurately measure the timing of slot car motor armatures. (Please click photos to enlarge)
 |
Carefully engage the small index bolt on the gauge of the meter into a slot of the collector. The snap-in is effected by spring pressure. | |
 |
Push the opposing holder (on the picture above) onto the armature shaft and center the gap between the windings with the large index bolt. | |
 |
The exact timing of the armature can now be read off the large dimensioned scale. | |
 |
Spacers can be used to adjust the height to the appropriate stack length, for example Stack .250 or Stack .500, etc. |
