Regarding that cantankerous troublesome lower-edge of
the two plastic halves when taking apart a "spice" HP-34C.............
Did anybody try sliding a steel ruler between the
two halves, along that troublesome lower edge,
sliding it in between the two uncooperative halves ?
The trick is to allow the back-half
to slide translationally past the top-half, true?
But it doesn't slide because of the molded ledge
on the top-half. A thin, stiff piece of metal would
allow it to slide past the top-half.
It may enough to use a steel-ruler. One of those shiny spring-metal drafter's templates (the ones about 2" x 4") would be even thinner. The ultimate would be a piece of .010" Tungsten metal foil (nothing is stiffer than Tungsten while avoiding britleness). But I haven't seen any of that since I was working in a laboratory.
Once the stiff piece of metal is in between, the back-half should translate past the top-half and the clamp should release?
Wanted to know if anybody else had tried this.
