SATYR (Armature for nymph Day 2)
PLACEMENT OF SUPPORT
I have taken the original sketch and laid in the two basic armatures as red lines. The 14 gauge wire will support each of these figures on its own so I know that I will not need any special support just for them.
The green line is the support for the entire piece. We want this support to be along as direct a line as can be from the base to the bulk of the second figure. It will bend and curve to fit along the male armature but is relatively strait. The picture shows the green support stopping at the hand of the female but we really want the support to run all the way to the shoulder so we are close to the bulk (torso) of the supported female.
SIZE OF SUPPORT
This is going to be an experience issue. I have worked in bronze and other metals for about 20 years so I have a "feel" for how metal stresses and fails. A nice test at home for those who did not manage a foundry is to take some different rods of assorted diameters, bend them in an arc, and hang some weight on the end.
Once the armatures are assembled, you can work out the balance issue. Each figure will weigh about the same so I want to make the hands the center of a seesaw with the same weight on each side. The hands will align over the foot which inserts into the base so if the piece pivots, the weight stays balanced. All I need to do is gently adjust the bends at the ankle and shoulder until the figures stand in the base without falling one way or the other. Test this by pushing then side to side. they should right themselves without falling over.
I hope this explains the process a bit more for you.
As mention before, the female armature starts out as a simple wire armature just like we used for Tristan. I have then straightened one arm and shoulder and cut down the wrapping of the spine to open half the armature so we can build on it.
Keep in mind-SIMPLE. The standard armature will support the clay. The spine has four wires in it so it is very rigid. If we transfer the stress of supporting the figure into the spine, she will hold herself up without anything else added.
She will simply be hung from the support by her arm so no extra support is needed in the legs.
I cut a 5/32" tube as long as her spine and shoulder added together and slipped it over the 14g. wire. We are going to build a rod in place on the armature by slipping tubes over tubes for support.
This tube is larger than my support rod so it will slide down the rod to the male hand. I now have what will become a hollow arm on the woman which slides over the solid support rod from the male.
Tomorrow we will start on the male torso.
Have a great day!
