The
framework comprising the base and the two uprights may be made
either of hardwood or asbestos board, says Popular Electricity. If
constructed of the former, the portion of the base under the coil,
and the inside surfaces of the two uprights should be covered with
a 1/8-in. sheet of well made asbestos paper, or thin asbestos
board may be substituted for this lining. Asbestos board is to be
preferred, and this material in almost any degree of hardness may
be purchased. It can be worked into shape and will hold wood
screws. The detail drawing gives all dimensions necessary to shape
the wood or asbestos board.
After preparing the base and uprights, drill 15 holes, 1/4 in.
deep, into the inside face of each upright to support the No. 6
gauge wires shown. The wires at the top and bottom for holding the
resistance wire are covered with asbestos paper and the holes for
these wires are 3/4 in. from the top and bottom, respectively, of
the uprights. The wires that form the cage about the heater coil
and are used for a support for the toast are 15 pieces of No. 6
gauge iron wire each 8 in. long.
