Twin Drive

I went ahead and mounted the second Gear Drive system.
I have some work to do to this shoulder, But I wanted to see how they
would look inside the droid.

More 2-3-2

The drive system is bolted in the frame now.
I had a hard time figuring out how to bolt all the parts and being able to get to
the screws.
I drilled a 1/2 inch hole just above the main shaft on the gear and the way I bolt everything is:
Bolt the bearing to the frame, Through the 1/2 inch hole screw the body to shoulder hub
to the outer flange of the bearing.
Then mount the drive system into the frame.
I'll show pictures next time.
Now the only thing I need is the drive motor. getting the right size, speed and strength will be the hardest part.

Shoulder Work

I cut a body to leg circle today and I routed into it to mount a aluminum
plate. The plate will act as a gear so the D shaft from the gear box will
have something to lock and turn the legs.

You can see the bearing bolts to the circle and the aluminum plate is under it.
The shoulder looks off right now because I need to sand it with my drum sander to true the circle.
It really is not that far out of round it's just the camera makes it look bad.
The bottom picture shows the gear box inside the frame. It's not bolted yet,
It's just for the picture.

2-3-2 Motor

I got this motor setup out of a brand new Linear Garage Door Opener.
The opener is rated at 1/2 Hp and can lift up to a 18 foot x 7 foot garage door.
It's more than enough to move the legs.
It already has limit switches built into the drive system.
All I need is to locate another one for the other outer leg.
