I used 2,5 mm copper wire for the base. I used copper beacuse I could not find this thick aluminum wire here. If you find aluminum it should be better.
0,9 mm aluminum wire for the arms and hands over copper wire.
Covering wire with epoxy putty for the bones. I did not use 5 min. epoxy. I made couple different armatures and tested. I even tried using super sculpy for the bones. I ended up using Pattex 15min epoxy which seems stronger.
notice the nuts inside epoxy feet for tie downs
