Suitable Dial Bore Gauge

Hi everyone,

Looking at buying a dial bore gauge for engine assembly.

What's a suitable graduation/resolution for engine building?

Thanks

The gauge I'm using is a metric gauge that has a precision of 0.01 mm. The commonly available imperial dial gauges will measure down to 0.001". These are sufficient for most purposes. you can purchase dial gauges that are more precise but you find that the costs start ramping up quite sharply.
