I have an exhaust manifold, a turbine housing and a swingvalve housing that I need the mating surfaces to be machined flat, no one seems to want to do it.
I visited two automotive machine shop, they say they can't do it.
I visited two custom machine shop, one says they don't have the correct machine, the other doesn't do any outside work.
Other than a belt sander machine or put a sand paper on the glass top, anyone know of any shop that would machine the surface flat?
