Disassembled the L. side HS and deburred all holes. Then, tried out the new C-frame. Works like a champ, and setting it up on ther end of the CNC machine made a great workspace for these smaller sheets. Only a few hole that could not be reached with the C- Frame. Those were either done with the hand squeezer, or the "Close Quarters" POP rivet dies i got from Cleaveland aircraft. They worked great, Glad i had to forsight to order them before the day i needed them!
