Select Faces of the Actuating Coupler shown above.

<< FRONT VIEW >>
With the faces selected Extrude out to the first corner. (Red Arrow)
|
<< FRONT VIEW >>
With the faces still selected Extrude again out to the upper corner. (Red Arrow)
*Notice that the extrusion does not align up because the Actuating Coupler is angled slightly.
.

<< FRONT VIEW >>
Select the following vertices of the Actuating Coupler with the lasso tool. *Note that not all the vertices are selected. The lower left-hand corner and middle vertices are not selected.
Rotate the vertices to align with the diagram. It is very sensitive

Create the Shoulder Hub
Create a cylinder with 20 division (defaultdeafault) rotate and scale it to align with the blueprint above. This time scale it slightly smaller so that there is a decent gap.
|
<< FRONT VIEW >>
Also position and scale the Shoulder Hub in the front view.
|
<< PERSPECTIVE VIEW >>
The Shoulder Hub should stick out a bit.
|
<< PERSPECTIVE VIEW >>
Select and delete the back faces of the Shoulder Hub.
|
<< SIDE VIEW >>
*Rings not centered in image
<< PERSPECTIVE VIEW >>
This is a two step process. Select the center faces and extrude. Change the Offset to 0.035. This will scale down the faces.
Extrude again. This time change the Thickness to -0.06 which will push the faces back 0.06 units.

<< SIDE VIEW >>
*Rings not centered in image
<< PERSPECTIVE VIEW >>
This is also a two step process. Select the center faces and extrude. Change the Offset to 0.035. This will scale down the faces.
Extrude once again. This time change the Thickness to 0.04 which will push the faces back 0.04 units.
|
<< SIDE VIEW >> *Rings not centered in image
<< FRONT VIEW >>
This is also a two step process. Select the center faces and extrude. Change the Offset to 0.08. This will scale down the faces.
Extrude once again. This time change the Thickness to -0.45 which will push the faces back 0.45 units.

<< PERSPECTIVE VIEW >>
As you can see the main leg gets in the way . . . Let’s hide it.
Select the main section of the leg and press {Ctrl} + {h}
*To unhide, press {Ctrl} + {Shift} + {h}
Another way is to isolate an object. Select the object(s) and press {Alt} + {i}. This hides everything else.
|
<< PERSPECTIVE VIEW >>
Select the following faces.
|
<< PERSPECTIVE VIEW >>
Extrude the selected faces inward, change the Thickness to –0.07 or 0.07 depending on the direction it extrudes.
|
<< FRONT VIEW >>
Switch to Face Mode, select the back faces of the newly extruded section. Scale them
|
<< SIDE VIEW >>
Scale the faces to align with the edge as shown above.
*Rings not centered in image
|
<< FRONT VIEW >>
The Shoulder Hub should look like this in the side view.
|
<< PERSPECTIVE VIEW >>
The Shoulder Hub should look like this in the perspective view.
|
<< PERSPECTIVE VIEW >>
We need to see the main leg again . . .
So let’s unhide it. There are a number of ways:
First try to unhide it, press {Ctrl} + {Shift} + {h} this unhides last hidden object.
If it doesn’t reappear, you can open the Outliner or Hypergraph, find the leg, select it and then Display > Show > Show Selection
The last way is to show all Display > Show > Show All
|
<< FRONT VIEW >>
Select the newly extruded Shoulder Hub, Duplicate it {Ctrl} + {d} and then hide it {Ctrl} + {h} .
Select the 2nd Shoulder Hub and and scale it as shown above. We are going to use it as a cookie cutter.
*I scaled it only in the Y direction.
|
<< FRONT VIEW >>
Select the leg and then the stretch out Shoulder Hub. We are going to perform a Boolean operation or in other words, subtract the Shoulder Hub from the leg. Mesh > Booleans > Difference
|
<< PERSPECTIVE VIEW >>
It should look like this.
|
<< PERSPECTIVE VIEW >>
Now show the duplicated Shoulder Hub.
There are a number of ways:
First try to unhide it, press {Ctrl} + {Shift} + {h} this unhides last hidden object.
If it doesn’t reappear, you can open the Outliner or Hypergraph, find the leg, select it and then Display > Show > Show Selection
The last way is to show all Display > Show > Show All
