The attached roller bearing, made by the Chain Roller Bearing Co., will fit the back axle pinion bearing of either Goshawk I or Goshawk II. We think it might be worth while building up one of these axles with this type of roller bearing to see if it has any advantages over the Hoffman type. DA.{Bernard Day - Chassis Design} | ||
