more pics of stuff i have made or jobs in the shop, will try to explain what i can. first 2pics are my FAA certification card which documents me with the FAA as a repair machinist. there was a pretty extensive back ground check, it took about 3 months to get this. they do a criminal, job history, schooling/training check, and im not sure what else. the FAA can at ANY time come to our shop and drug test me on the spot. 3rd pic ir just a part that has a worn area that needs to be repaired. 4th &5th pic are caller deverter valves for main engine start for i believe 747's and 767's. they use auxiliary engine that once its exhaust is up to temp it is deverted to the main engine to start. that is how it was explained to me. this lathe has been setup just for this part for the last 15+ years!. the company has been doing these parts for mare then 25yrs. the tracer attachment was too much trouble to keep setting up so they decided to just leave it that way. we get these dozens of times a year in new and used condition to either upgrade or repiar with our coatings. i will post more pics later, got to go to work.
