The Hacker A30-16M is 38mm in diameter and so does not fit in the tiny hole for the Permax400. The idea was simple enough, make room and make it stable. Looking at the hole I would need to enlarge made me realise that enlarging it would need the kind of delicacy that I simply couldn't achieve with any sort of implement (machine or otherwise). So I carefully trimmed of sections to try and make it look nice as well as fit but that did not work until I got right down. I followed the curve of the motor inlet and the straight edge on the inside of the motor mount until they met to create a semicircular pit for the motor.
I marked up the front of a CD jewel case for drilling the mounting holes (using the metal motor mount supplied). I then put a 1" masking tape strip on the jewel case centered over the mounting holes. I used a soldering iron to burn along the edges of the masking tape. By now I had a rectangular plastic piece with holes in it. I attached this to the motor with the screws supplied and used the soldering iron the curve the upper edges. I later used the soldering iron to "trim" the rectangle to fit above the magnet mounting point.
The only thing left was to cut a little valley to CA glue the mount into so I used masking tape to help the motor where I wanted it and cut out a valley. Once done I pressed the halves of the chassis together enough to create an impression and did the valley cut for the opposite side.
Pants I forgot the wires another valley was cut to fit the wire just in front of the mount cut and after the CA glue had dried. Again both halves received the cuts (for balance and ease).
