III.  SKELETAL RECONSTRUCTION - PART II 

 

In today's lab you will follow the guide book to finish reconstructing your skeleton, including the following major steps:

 

1)  Determine what additional supports or struts will be needed to support the axial skeleton.  Fashion these with the instructor's help and mount these to the wooden base.

 

3)   Suspend the axial skeleton and attach each of the appendages.

 

3)   Attach the skull and tail.

 

4)   Check your skeletal mount for structural integrity.  Reinforce the joints as necessary by carefully adding hot glue and/or super glue.
