Then all modifications, porting, machining blueprinting, and ending to all critical surfaces is done. Up coming the areas receive a superior temperature detergent bath and substantial pressure rinse by a 10hp cleaning device. Soon after this, pre-assembly starts plus more inspections. To move the pre-assembly inspections, a crucial surface finish of 12-18 micron is required.
