I'll never use either of those at work, but i'll be screwing together a few engines in the future and these will certainly come in handy, added to the list if i don't run out of money.
You can have any brew you want... as long as it's a Datsun / Corolla / What is that?
Use an inside mic if your unfamiliar with the T gauge, however T gauges can hit your really small inside diams where you might struggle with an inside mic, make your verniers Digital and get a set of 200 mm and 150 mm ones imo, Starret or Mitutoyo anything else isnt really worth your time, (personal preference) also i believe you can measure with a vernier on T gauges, but i wouldnt be trusting it if you have a tolerance above + / - 0.03![]()
