Adventures in Sculpting, Part 3

Now we have a plan!

In yesterdays picture, you could see the beginnings of an armature for the upper body. Today comes the fun part: cutting lengths of aluminum armature wire for the actual armature. Well, it would be if I had watched the video instead of plowing on... again. :P

But, moving on... The armature will be supporting approximately 2-3 pounds of pastalina (oil-based modeling clay, which I'm really hoping is mildly recyclable after molding. Cause its a little expensive. Not bad as far as clay goes, but I'm cheap.).

The base will be a 12"x12"x1" wood board. The supports for the armature consist of galvanized steal pipe attached to the board with a flange and wood screws. The supports on the feet are bolted to the board from the bottom and ancored with some of the 2part epoxy putty.

Here is the picture from part 1. You can see the pipe sitting on the table. The t-section will actually reside in the navel of the armature.

Now, obviously, I'll have to use slightly smaller pipes to support my smaller armature. But you get the idea.

Alright! Next, we draw from the top of the sternum on the front view of the armature map down through the center to about 1/2 way between the navel line and the crotch. Then, from that point, draw to where the insertion of the leg would be and then straight down to the bottom of the foot. Repeat this idea for the arm: Sternum to shoulder, elbow, wrist and a little ways beyond the hand for the fingers (like 1/4"). Be sure and make pivot points for where the hip is, knee, elbow, wrist, ankles, etc.

So, since we're going to make the arms and head removable, we're going to measure the wire about 1/4" beyond the shoulder pivot and down along the spine line and through to 1/4" beyond the foot. Loop and go back up past the navel and cut. Repeat on the other side. Straighten out the wire, except where the foot loop is. Twist the overlap together and epoxy into the t-pipe section where it would sit comfortably inside the sculpture. This is where it would be easier to show you, but since I did it a little different, I think I'll cover this on the next sculpture attempt.

Mine looked like this when I was done putting the armature beginnings along with the wired on head piece.

Now would be a good time to mark with small pieces of duct tape where the knees are for later reference.

Just wanted to say thanks for the comment on my blog. This looks like a pretty cool project your working on. Good idea fitting the armature into the sketch, I’ll have to adopt that.

Thanks! I wish it was my idea... It was on the video series we got. If you have time, you should check out the gnomon website. Its crazy good stuff on there. Little spendy sometimes... but the teaser clips are pretty helpful. :D
