Pinewood Derby Wheel Inspection Gauge Go / No-Go

$14.95

Our Wheel Go/No-go gauge will help you improve your race by providing a consistent and quick way to inspect pinewood derby wheels while the wheels are mounted on the car.  Inspection is a breeze once you understand how to use this tool and there will be no arguing about caliper bias.

Please do not try and force the wheel between the tongs. Simply try to pass the gauge through the wheel from the bottom up. If the wheel does not pass through then the wheel PASSES inspection. If the wheel is able to pass through the tongs, then it fails that measurement.

Weight reduced wheels are very pliable and thus calipers will make them fail every time.  Bring one of these guides on race day to ensure you do not get D/Q because of measuring bias.  If a car is built with wheel wells (fenders) , the OD gauges cannot be used (of course a digital caliper cannot be used in this situation either).  Be prepared.

  • No Wheel Modification Allowed – If the wheels may not be sanded or modified in any way, then use the 1.180 OD gauge and the .360 width gauge.
  • Wheel Modification Allowed – If the wheels may be sanded or lathed, then use the 1.170 OD gauge and the .320 width gauge unless otherwise stated by your packs rules.
