These are photos of the planing of the metal sheets into the correct thicknesses for our new organ pipes.
Werner Ullrich in Hamburg, Germany customizes the metal sheets for the pipes. After mounting the sheets on 16′ chipping machine (made in bella Italia 1959), three cycles are necessary to archive a superb surface.
First rough chipping for an even surface. Second chipping for adjusting the correct thickness. Third machining for a final shining appearance.
