Last two nights I have been working on the motor drive sprockets.

I had to make an adapter for the centre of the sprocket so I could centre
 the hole saw in the sprocket for drilling the hole for the hub.

 I then drilled a hole in a board to put the adapter into.

Now I can put the sprockets on and have a centre hole for the drilling.

28mm tungsten carbide tipped 28mm Hole Saw.

Drilled the mounting holes to hold the sprocket onto the hub.

Drilled the centre hole for the hub.

Fit perfect.

Both drive sprockets fitted.

I also made the plates for holding the clear acrylic for when I make
the lenses for the eyes. I will have photos of this tomorrow.
