Abstract: A go/no go pipe deflection gauge to be pulled through a pipe to determine whether the pipe wall has been deflected from a substantially circular cross-section. The gauge includes a spindle having an axis of length and a pair of ends. A cable can be connected to both of said ends so that the cable can pull the gauge through a pipe, and pull it back out if it becomes stuck. A plurality of vanes extends radially from the spindle. The vanes are angularly spaced from one another and extend parallel to the spindle axis. Each of the vanes has an outer boundary which includes a central substantially straight segment parallel to the axis, and a pair of end segments extending from the respective ends of the central segment toward the axis.
