1. What is one type of job (such as installing hand-guards or a buttstock) where you think it would be appropriate to complete your measurements using a tape or rule? When would you need a caliper? When would you need a micrometer?
  2. Explain what the course text means when it says the “dial indicator is used to measure ‘travel’ or play”.
  3. Another use for the dial indicator is measuring “runout”. Define the term “runout”, and cite one job or project you think a gunsmith might undertake in which measuring runout would be important.
