Essential measuring tools for the home shop

[PixMan]

I have the Starrett versions of those small hole gauges, both the full round set S829EZ and the half-round S830EZ, plus for larger holes the S579EZ set of telescopic with dual sliding arms. The No.579 telescopic work fine and I trust my meaurements within .001". I really don't care for the feel of the 829/830 gauges, and prefer to use gauge pins. The trouble is, I haven't bought any of those yet. ;)
