Matt wax ring sizer is a ring mandrel specially machined to incorporate a cutting steel blade that extends from the handle to the tip. To enlarge the finger size in a wax ring model or ring tube, slide this tool through the hole abd gently rotate clockwise, after two or three rotations remove the ring sizer, turn the wax ring and repeat the operation throught the other side.
With each turn the blade scrapes the inner wall enlarging the wax ring to the desired size which is clearly marked along the ring sizer.
