September saw about 16 members show up for our meeting.

to make the shell of his electric furnace. He plans to keep us posted as
he solves the various problems involved in getting his setup going.

Chris Helgesen brought in a race car spindle that he had fabricated.
He discussed the improvements made of the stock unit and the considerations
involved in making the unit rugged enough for race duty.
Dave Welser brought in an "English wheel" device for forming gentle curves in sheet metal.

Horse trading was lively this night. In addition to the English wheel finding
a new home with Chris Daniel, a hand tapper that John McCalla had brought
followed Dave Welser home.
The meeting continued with general discussion until we had dwindled to a handful and then ended about 11:30 PM. The night owls once again headed out for late night eats.
