Sorry if I was a little conufsing. This is what I was looking for feedback on:

http://www.shotguncombogauge.com/combogauge.html

The same company has other tools, but this is the actual "combo gauge."

I have seen the Galazan thickness gauge in action and really like it. I just don't do enough with shotguns to justify it at this time. If I were to start doing shotgun work to any extent, then I would get the Galazan tool and never look back. I thought about making one, but with the time and materials it would take me, I would just as soon buy it.
