Brad in Wisconsin Posted May 28, 2007 Share Posted May 28, 2007 Does anyone know what these gauges are. They go from 1 - 16, the ring is 4' in diameter. The number 16 plug is a 1/4' in diameter. The number 1 is 1/8' in diameter. What are these plugs used to measure. Link to comment Share on other sites More sharing options...
Guest Faust Posted June 13, 2007 Share Posted June 13, 2007 Looks like a form of "thread gauge" I still see in use, at places like Home Depot. I am assuming that the threads are are all different, but duplicated in "male" and "female" Link to comment Share on other sites More sharing options...
Brad in Wisconsin Posted August 14, 2011 Author Share Posted August 14, 2011 wanted to revive this post ........the plugs have a series of rings but they are not threads made of pot/monkey metal if your English Link to comment Share on other sites More sharing options...
Guest prs519 Posted August 14, 2011 Share Posted August 14, 2011 Are there duplicates? Seems like there must be, since it does not seem reasonabler thatsomeone would split the the one-eighth interval into 16 equal fractions? It appears the ring can come apart to add or remove the "gauges"? Reminds me for some reason of something to do with gas like acetylene or some such. I have no idea where that thought comes from...ho! Link to comment Share on other sites More sharing options...
