First we put the flange on the machine and made holes in it so we can use them later as a center for alignment for milling the arcs of the part.
And start with roughing .
After making sure the workpiece is in the center of the machine I started with
roughing the outer arc.
After that we are roughing the cylindrical section and then turn over the workpiece and cut away the biggest arc.
But first we made the small arc .
After finishing the outer arc the arc shaped slots ware made.
In a later stage the piece is taken in the chuck of my lathe.
The first operations are facing of and drilling .
With a other tool we made the chamber for the motor.
After turning over the workpiece the other side is machined .
Now the workpiece is going back to the milling machine and it is centered and holes ware made in to it so the motor can be attached .
In to the side of the flange a tapped hole is made to attach a handle for tightening the belt of the motor.
now the motor flange is ready for paint.
