Now that I have a lovely granite plate in my shed (thanks Greg and John ) I need to buy or make some metrology tools. (I am new to machining so have limited stuff)

I think my plan is to use the mill, lathe and surface grinder to make some bits - squareness comparator, 123 blocks and possibly indicator holders. In order to make measurement tools it appears I need measurement tools (chicken and egg) to ensure accuracy.

How would you peeps suggest I proceed? Are there some basic measurement tools I need to buy such as indicator holders, angle plate, height gauge so that I can make other stuff? I have a few indicators although I cannot recall if they are tenths (or the real world equivalent - 0.001mm?). I cannot throw a huge amount of money at this hence the desire to make stuff (plus its fun and interesting).

Where would you suggest I source the bits you think I need? There are plenty of places selling the Chinese Vertex brand. I have nothing against Chinese as long as its accurate. Anybody got excess bits laying around that you want to sell?

Any thoughts appreciated as I am a little lost.............
