for the overlay, and manually impressed rivets with a scriber.
The great advantage of the transparency is that you can posi-
tion graph paper underneath, to guide the formation of exactly
spaced and aligned rivets.
For supports, I cut two from 1/8" balsa sheet, with an upper
radius to fit the tank. I painted these a concrete color, as shown
in (20).
The rivet-impressed overlay sheets were glued to the paper tube
with canopy glue. Then I sprayed the finished tank with gray
primer, and it is shown on the supports in (21). The finish color
was silver, followed by weathering with acrylic washes.
The propane tank
Propane was a
relatively new fuel
in 1953, but some
dealers in rural
areas were begin-
ning to supply it.
I decided to add
such a capability
to my bulk plant.
I began with a
length of Plastruct
tubing, 7/8"
diameter, which
I cut to about a
6-1/2" length.
Plastruct makes
hemispherical
ends for this tube
diameter, part no.

ered tanks are attached to the base,
with walkways and the stile remain-
ing to be attached.
