Was section lead QA for 2 years

These are used almost daily.

JB Machine 1997-1999

Calipers, indicators, 0 to 6” mikes, telescope gages, inside mikes were used daily to produce lathe and mill parts. Also used groove mikes and snap gages to inspect oring and snap ring grooves,

Used many of these daily.

Performed as found, assembly, and final reads on gas turbine overhaul. Using feelers depth mikes, plastigage for bearing . During alignments used feelers, mikes,and indicators

. At Metropolitan Water District as shop machinist see standard shop bench tools, mikes to 6”, calipers to 18”, bore and telescope gages as needed. Did precision layouts with height gages.

2002-present LADWP During field work regularly used ID and OD mikes; to 24”; feelers, calipers and telescope gages. During shop work use height gages ID and OD mikes to 6”, calipers to 12” on a daily basis.
