seams every six scale feet across the overall height of 60 scale
feet. Then I measured the vertical seams half the width of the
sheet, every 15.1 scale feet, skipping every other weld seam so
the joints wouldn’t overlap. The final step was to cut the width
of the sheet at 22.78 scale feet, which is the correct circumfer-
ence for the 1” PVC pipe.
Wrapping the styrene is a bit of a challenge, but as shown in
the photos it’s not as difficult as it looks, particularly if the seam
isn’t visible on the completed model (thereby not requiring any
sanding or filling). Finding suitable conical shapes for the silo
bottoms was accomplished by perusing the local Michael’s Craft
store cooking and cake decorating section. A company named
“Wilton” makes frosting application cones which were about the
20
20. Partially completed silo base with auger installed
and some of the .020” by .060” diagonal bracing and
horizontal .060” angle glued in place between each
column support.
