I bought the ME Threadpal from MRainey a few years ago (I don't really remember how long exactly). I use it ALL the time. It is so cool to be able to get the measurements over wires for various thread sizes with a few inputs. Amazing! This is not a paid endorsement - I don't even know MRainey except from this forum. For those of you who are like me and do all kinds of threads and don't want to pay for or sit on a bunch of thread gages this is really cool software. Just sayin'
