TITLE
1) PREPARE (OR SELECT) A FLAT MOUNTING
SURFACE OVER A MINIMUM .32 DIAMETER. SURFACE
SHOULD BE FLAT TO .001 TIR FOR BEST HIGH
FREQUENCY RESPONSE.
2) AT THE CENTER, DRILL #50 (Ø .070) X .20 DEEP.
3) TAP #2-56 UNC-2B X .125 MIN DEPTH.
4) CLEAN THE AREA CAREFULLY AFTER MACHINING
TO REMOVE ALL CHIPS AND CUTTING OILS.
