The old engine has just been removed, I've taken out the centering pins, leaving two oblong holes. I've made a third one at the top of the photo.

The surface of the support plate is ribbed so that the Loncin motor rests well on a flat surface; I made a new plate out of 4mm sheet metal to receive the motor.

Three spacers are inserted between the new plate and the old one to allow the screw heads to pass through.
