@Wayne has achieved another great milestone in the development of his famous charts. You'll find these charts, organized by vendor, extremely useful in your penmaking. The Apple and Android apps have not yet been updated, but that's in the works.
I just looked at the app that I have installed on my phone. I am assuming that it updated on its own or I must have not been paying attention. But WOW! Have the instructions is awesome and having the drill bit size conversion function has just made my day!
Again, thanks for all the hard work you put into this! This Rocks!
