"Ferrosaurus YSC-iccus:"
(October, 2003)
For the second annual "overnight at the Farm," the Math
Team (group of teens I work with at the Museum, in the Youth Science
Center) and I came up with a couple of projects using welding tools
and steel. The first started with a trip to the Museum's store, where
we picked up one of those wooden dinosaur models (where the pieces interlock
at right angles). We chose a stegosaurus model because it looked the
most sculptural. I traced the pieces, and set up the toolpaths (70 of
them), and then cut them on my
home-built CNC plasma cutting table at the Farm. When the kids came
out, we started to piece the skeleton together, and everyone took turns
using the MIG welder ("wirefeed"):

Some grinding, and more welding, then transport to the Museum:

Temporary home, in the YSC:
Our second project involved heat-bending a fractal shape, using teams
of two people-- one directing the oxyacetylene torch, and the other
bending when the 1/2" steel softened as it glowed orange:

The resulting sculpture was presented to the Math Team's Lead (Chris
R.), as a wedding present.
