Finished dimpling the HS skins and started collecting the elevator parts.  The DRDT-2, pneumatic squeezer, and close quarters dimple die kit worked very well.  My steel mandrels for the close quarters dimple die did not last long enough for the holes so I emailed Cleaveland and they sent some replacements FREE of charge (they are finishing nails– 4 D  1.5 inch).  Great customer service.
