Hi, Richard-
Before working on ANY Vintage appliance, recite the Oath of Hippocrates which tells you to "DO NO HARM!".
The
T77 Toaster is a Gem made by GE, and is very easy to disassemble -
there are two nameplates that say "General Electric" - one on each end -
they about a quarter-inch wide and two inches long - simply pry them
off with a thin-blade knife, exposing a small, sheet metal screw
holding the upper shell. Pull off the two small curved knobs that
control the "color" and "pop-up" levers, and the upper shell should be
free. On most models, the end pieces slide down away from the lower
body, which can be removed by removing the screws holding it to the
metal chassis.
The toaster presents no
hazards - the original cord is Type HPD, which is a cotton-covered
asbestos-insulated cord, U/L Red Label, rated at 3,000 cycles (bends).
The elements are wound with flat nichrome wire on Mica Sheets - mica is a
mineral substance mined from the earth, and presents no hazzard. If
you replace the cord, it must be type HPN, a neoprene cord rated to be
used on a Heating Appliance. DO NOT use a plastic insulated cord on a
heating appliance. It is not necessary to use a three-wire cord as the
appliance was manufactured before they were required. The only hazzard
from the asbestos cord is if you inhale the fibers, which can cause lung
cancer.
If the mica element is damaged,
there is no "glue" or silicone product which can be used to repair it -
that flat nichrome wire gets red-hot and will burn anything but the
original mica, or its replacement, Micarta board, which is the only
suitable replacement. Micarta board is used on some microwave ovens as a
waveguide cover, and is readily-available in a size which can be cut to
the shape and size to repair a broken element.
When
you work on a vintage appliance, remember that it is valuable to a
collector and there are no replacement parts available from the factory,
so be very careful not to cause irreparable harm.
