can complete the cutting operation in one stroke. I cut 72° of each end
of 100 firebricks (see photo 2), grooved them, and then restacked them
in their boxes with the chaffing strips--as they are very fragile. All
end cuts were saved as well as the useable powdered firebrick. There
was a surprising amount of this powder all over me, the saw, and the
backyard where I had had the sense to do the cutting.

The elements were wound on a 3/16" cold rolled steel rod--I later
found that they should have been wound on a 3/16" hardwood dowel as
elements should never touch steel, As a frame for winding the ele-
ments, two two-by-fours were braced against the ceiling in my apart-
ment at about 4-1/2' apart. A 3/16" hole was drilled in each one at
about waist height. The rod was passed through the holes and a hand
operated wood drill was applied to one end of the rod. The contraption
resembled a medieval ox-spit. Miss Anna K. Hill supplied the motive
power on the drill and the element wire was clamped to the rod with a
2""C-clamp. The spool of 410 feet of wire was placed on a peg which
allowed it to turn freely, My right hand was curled around the wire
and my left hand was curled around the rod, both thumbs applied even
pressure to the wire--after a few false starts we were having
enormous success. (See photo 1).

The bricks were taken to a packing and shipping company where the
sets of twelve bricks were fastened into a unit with strapping iron.
Then, later, at home I squatted inside the rings and ruined my 3/8"
drill by grinding a gutter in each element groove inside each ring of
bricks. This could have been done previously with a table saw by
simply tilting the blade.
