[jpdesroc]

Thanks for your nice comment Dave,

I used an old Hammond M organ scanner AO-21869 like this one:

Notice the small 'bit' that goes out at the center of the rotating
piece. This is where I screwed (a very tight space..) the machined brass
cylinder..

that goes inside my linking spring to the DC motor..
