As soon as my parts have emerged from the machine shop, I will supply detailed photographs. My parts were created by successful B9 builder Gwen Meunier and are identical to hers. So, in the meantime, here are some photographs that I snapped of Gwen Meunier's ingenious design for the aluminum assembly consisting of the donut, waist plate, and toothed Rockler lazy Susan. My donut and waist plate assembly is identical in design. I hope it will be identical in execution.

The first picture is of the entire unit assembled. Each picture shows successive layers of parts being removed to reveal the part underneath.

Gwen Meunier very cleverly designed a top plate that sits on top of the lazy Susan. This serves as a floor to the torso and serves to hold any devices or racks that cannot be mounted to the interior sides of the robot's torso.

With the top plate removed, one can see the toothed lazy Susan. A gear wheel, run by a motor, spins the lazy Susan around. I believe that this is a superior design to that more conventional system of using a rubber wheel to turn the lazy Susan. A gear wheel need not sit so tight against the lazy susan, would not have any slippage, and would require much less power to drive.

Here is another shot of the toothed lazy Susan. You can also see the bay cut into the waist plate to make room for the drive motor.

Now, the lazy susan has been lifted out of the aluminum donut. You can see that Gwen has set four bolts to attach the waist plate to the white sub-waist plate beneath it. The sub-waist plate serves to hold up the rubber legs, the top of which are sandwiched between the sub-waist plate and the waist plate.

Finally, the donut has been lifted off of the waist plate. It is clear that this assembly would not allow Gwen's robot to be used as a costume.

My donut and waist plate assembly is identical. My machinist is performing the following tasks:

• Cut out a hole in the solid waist plate
• Cut gear teeth into the lazy susan
• Drill holes into the solid top plate to accept the bolts coming up out of the lazy Susan
• Drilling holes up from the bottom plane of the waist plate through the donut to accept bolts to attach the two structures
• Drill holes through the sub-waist plate and the waist plate so that bolts can attach these two structures.
• Buff, polish, and glass bead blast the exposed aluminum surfaces
