Looking for a good machine shop in the Sterling area of close by.
Any help? Where not to go is good also....................

Depending on the complexity of the work, Allied Machine in Falls Church is quite good. But they are old school so if it's high performance stuff, I can't say how they would do. They do lots of work for dealers and can even fix Ford cyl head plug holes with a guarantee.

C&C in Manassas and T&G Performance in Waldorf

George's Machine shop in Clinton MD. does a pretty good job on a wide range of parts- I cannot remember if there is anything they could NOT do. Burtonsville Performance and Machine in Burtonsville is also recommended.

I second C&C. Carol Carter who runs the place is a really good guy.
