Plus all the mics, a good swiss .0001" test indicator, etc, etc. The Starrett Vernier Protractor is pretty handy as well. But those are for the extreme precision situations...

Better to have more precision than you need than not enough. Nick,

Speaking from painful experience, it’s like many other things. Better to have more precision than you need than not enough.

You ideally want under .001" over the total length, if not .0005" total for precision work, especially when aligning machines and setting up work. Borwn and Sharpe (although an old US brand, they are likely imported) has a 3 piece set that is good to .0006" for about $53.00 from Enco. It all depends on how much precision you need... .0005″ per inch is ok for a 2″ square, but for a 6″ (.003″ out) or 8″ (.004″ out) and up it’s really only good for woodworking & welding.

This is not that bad of a price. I might just raid some from my dads garage though. I hope he doesn't read this...
