The equipment for this lab can be
made very inexpensively.
- The base is a 4' x 1" x
3" piece of wood.
- The pvc pipe I use has an outside
diameter of 7/8". Iy cost me $0.73 for a 10 foot section as a local hardware
store, (bought September 2000.)
- It uses cross supports made of
1/4" diameter wooden dowel rod, ($0.50 per 3 foot stick.)
- The wooden dowels are held on
to the pvc pipe with rubber bands.
- The foam insulation is cut in
half with a razor blade. Use a fresh blade.A fresh blade will take less effort
to cut, make clean cut and is safer than a dull blade.
- The foam insulation is held onto
the dowel with a piece of tape under the tube.
- To connect several insulation
tubes together, is a piece of pvc pipe big enough to snugly fit around the
insulation. I use a 1-1/4" pvc pipe coupler.
