Cork ring gauge.
Our new cork ring gauge is the result of the good work of Craig Crumbliss. Craig designed the gauge to help with sorting individual cork rings. The idea is pretty straightforward. You take a cork ring and slip it onto the gauge. The face of the gauge has a number of concentric circles with corresponding measurements. If you need a ring that is say 1 1/8" for a given grip you simply put a cork ring on the gauge and the concentric circles will show you if there are any major pits at 1 1/8". The gauge has a number of markings that will take you through the range of pretty much any grip or reel seat insert. There are also holes drilled at each measurement if you want to insert a fine tipped pen to mark the ring.
You can see from the picture below that the ring on the gauge has a large pit on the 1 1/4" and 1 1/8" part of the ring. The rest of the ring looks pretty good so you can space it accordingly.
The gauge is made from plexiglass.
