Sizing-up Progress in the Engine Shop

The engine shop at MMS Aviation has been a busy place lately.  Dale is supervising the assembly and test of a Lycoming engine for a ministry in Alaska.  Today cylinders and pistons were measured to assure proper clearance between them. 

Tim gave a mini refresher course about how to set up and use the cylinder bore gauge.  Dale, right, observes.

Dale measures each cylinder, checking dimensions in several places of the cylinder bore.

Joel records the dimensions on the engine build-up sheet as Dale gives him the gauge's reading.
