Carlos Puch


Materials needed:

-One DIN 6 pins, 270 degrees, audio type female plug.
-One mini-DIN male or female external plastic hood.
-One metal cylinder (aluminum, brass), with a center 3mm hole, aprox. 9mm
dia. -One bolt and one nut, aprox. 3mm (M3 or 1/8").

Construction:

1. Disassemble the DIN 6 connector (photo 1), leaving alone the inner plastic
piece.


 


2. Drill a ~3mm dia hole on the center pin hole of the piece, and join
the piece and the metal cylinder together using the bolt and the nut.



 

3. Mount the assembly on a drill, and, with the help of a file, reduce
the diameter of the plastic piece to, aprox. 10 mm. A LOW TURNING SPEED
MUST BE USED TO AVOID BURNING THE PLASTIC !!! (photo 3).



 

4. Finish the flat side of the piece with the file, mount the pins



 

5. Solder the wires and cover the back side of the connector with a
mini-DIN hood that must be cut to the appropriate length and glued with
super-glue.
