Peninsulators HQ was mid-San Francisco peninsula, only few miles from the
San Andreas fault. Yes, that San Andreas fault. Visualize an angry
giant picking up your house and shaking it. HARD. That's a big
earthquake, and they will happen here, the only question is when.
Lots of little ones are preferred, but sometimes they save up and you get
the big kahuna. But big or little, you must plan for them all.
At PHQ, we live by the motto "You can't fall off the floor."
If it's not mounted securely on a pin, it sits on the carpeted floor-- or
is safely packed in a box. Museum Wax et al are not positive enough. |

Crossarms with wood/steel pins are a good period choice-- every collection
should have a pole-top. But with original spacing, they don't hold many
insulators. Plus, the solid pins block the light, and they're not suitable
for windows or display cases. So: shelves.
But without a threaded pin, the glass is just sitting there, not held in
place. Waiting for the inevitable shaking. In a display case with front
doors the carnage is contained, but open shelving is disaster. How then
to safely display on shelves in a way that's unobtrusive?
