I found this topic while searching for machine shops to do work on my case, as I'm getting set to start a stock, reliable 1600 rebuild. I've gotten a lot of help and parts from AVR so far into the Square, but was surprised to read on here to try them for machining, I didn't think they did any. I went in there today to inquire and as suspected they don't do any machine work themselves, they outsource. Just thought I'd clarify. Apparently they give their work to The Bug Shop in Delta, so I'll be going there. Hope this is helpful to anyone else looking for local machining.
Cheers,
Lane
