Shop Math and Precision Measurement

If you can't trust the number, you can't trust the work. Real plant work runs on math you can do at the bench and measurements you can stake your name on. This volume builds both, without the classroom filler.

Shop Math and Precision Measurement is Volume 2 of The Journeyman Series, a ground-up path from high-school graduate to the technician a plant trusts with its hardest work. In plain shop-floor language, it teaches what a working technician actually needs from the first shift: shop arithmetic, algebra, geometry, and trig; unit conversions across US, metric, and process units; calipers, micrometers, and dial indicators; tolerances, gauges, and reading scales; and measurement error and significant figures.

Every volume comes in two editions: the trade paperback for reading and reference, and a companion 8x10 workbook of labs, worksheets, checklists, and competency sign-offs. In the workbook you read a vernier caliper and a micrometer, figure tank volume in gallons, measure runout with a dial indicator, and round and report a number to the precision the job actually needs. Get the numbers right and the rest of the trade gets easier.
