We wish to chromium plate the plungers and wedges to a thickness of .0005" the final diameter being as before. Will you please ascertain from New Hudson's what would be the cost on a production basis. We should also like to know the cost on production of enlarging the housing to cover the end of the expander, and allow of a press cap, as fitted to the hydraulic units.
