Morning guys,
Had to catch up on my reading this morning...you guys have really been posting this weekend.
Anyway, regarding the calibrated tools. At our shop, I'll allow all sorts of tools (homemade and store bought) that are used by the fitters, but.....the inspectors, I calibrate/verify every tool in their box. Any tool used for final inspection requires a calibration sticker. So far this approach has satified all of the auditors that have audited our shop.
When I started working as the QC, they had me verify every tool in the shop. I found this to be very time consuming and redundant. From then on, I rewrote our calibration procedure and I gathered up only the inspector's tools and gave them a check against our calibrated tools. After all the inspector's are the ones who will sign off that everything was fit-up correctly and if it isn't then the fitter gets to knock it all apart and refit it before he gets the "OK2W"(OK to weld).
Nice to have all calibrated/verified tools, but it isn't always necessary.
