I considered doing this to re-create swicth handles for the PDP-8 replica
I built a few years ago, but fortunately Robert Krten had a supply of
spare handles that he didn't need and was kind enough to supply them to
me.
At any rate, I think it's entirely feasible to make them with chemically
setting resins as Bill suggests. One day I'll even try this.
