i will work on getting them cleaned up and when i got the money ill get a manifold worked out for them but this is going to be a slow project. ill post some more info tomorrow but i am too tired right now.
take a piece of glass, say 18" sq., get some spray mount at Michael's or another art store, buy some 320 grit sand paper. adhere a sheet of sandpaper to the glass and use it to clean up the mating surfaces of those parts. just use even pressure and a circular motion. it's a poor man's mill.
