armature teaser
by sven at 11:59 pm
I just wanted to tease y'all a little... Saturday (3/25) I started work on a new armature.
The big picture:
- steel again
- actual ball-and-socket joints (rather than open-hole)
Design improvements:
- square stock at neck for better attachment of head
- body blocks perpendicular to incoming rods
- different shoulder design, to increase range of motion
- step-block wrist joints
- wire fingers
- ankles closer to soles of feet
- hinged toes
Changes in the construction process:
- drilling balls using mill (instead of lathe)
- brazing using oxy-propane "little torch"
- cleaning balls using Scotch-Brite pads
- doing rough-cuts using mini cut-off wheel
- on the mill, I've learned how to use a "wiggler" for locating edges
- using drill press for through-holes
- sandwich plates radiused using grinder (rather than a jig and rotary table)
- trimming the joints using Scotch-Brite wheel on grinder
- handy metal bowls to keep groups of parts together
More soon!
