The sheets I made for second shift so nobody had to wake up a lead at 2am. Twenty two pages, each one a single problem type with a worked example on a real print: bolt circles, chamfer and taper angles, sine bar setups, thread depth, drill point allowance, decimal and fractional conversion under time pressure, feeds and speeds arithmetic, and tolerance stack basics. No theory sections and no exercises with the answers in the back. Formatted to print at letter size and live inside a toolbox lid. Includes a version with metric callouts. PDF, immediate download, and you can copy it for your crew without asking me.
