Hi Mike
It's funny you should say that, out of all the junk I have on the wall in the shop the chart I have is the one thing that does'nt get covered up with jigs and other stuff, LOL
I keep most of them in my head but can't keep them all ,like drill hole size for a tap and thread size setup.
I think I use it every time I'm in the shop for something, it's a big one 24" x 36" so I can see it from 6 to 8ft away from it, that metic stuff gets me looking at it all the time,but then I find myseft more and more using the dig.mike to do the same thing but I just can't get along without it when it comes to drilling and taping.
I got mind from a company called Rickard's Ind.Tool Supply a nice white plastic one, they give them out for free with the Richard's name on the top, a write off item I'm sure and it works because I still use them from time to time.
At one time I got 12" cut off wheels from them by the case (144ea.) it's funny what you can recall when you thing about someone.
