[QUOTE="Grimly"] For accuracy, yes. A Vernier caliper is fine for rough work to the nearest mil or so, but I wouldn't believe it any finer than that. The digital Verniers might be more accurate, but I've a feeling it's simply putting icing on a pig.[/QUOTE] For the majority of work I do the good quality verniers I have are accurate enough. I checked them against the local machine shops test pieces - they were classed as "surprisingly good" by Fred; high praise indeed. I do have a couple of micrometers but I only really use them on bearings, journals and gudgeon pins.
