Any Machinist Custom/Modifying LF Camera Parts Like SKGrimes but in Southern California?

As title, is there anyone reputable and knowledgable like SKGrimes but in the West Coast? Hopefully Southern California.

I've worked with Machinists with no Camera/Photography backgrounds to make me parts and always something goes awry or they don't listen to my instructions causing additional delays. The machinists who work in cinemas near Hollywood and Pasadena won't touch what I need.

I know SKGrimes can understand and have done fantastic work for people in my network but sending my gear to rode Island is very heavy on shipping costs and I prefer someone local in Southern California.

For lenses, boards, shutters, adapters, (all relatively small things), the shipping cost is minimal compared to the cost of top-quality work.
As Rolls-Royce once advertised, 'the quality remains after the price is forgotten".
