Hi Ted,
I suggest that you DON'T use point in a cup, knife edge, or fishing
line.
Cardan type metal foil or wire, crossed metal foil or wires, ball on a
plane, crossed cylinders, rolling metal foil or wires all work OK in that
order.
On the LPVERTO or STM8 you need crossed foils. If you are using an AS1
type, a pair of crossed cylinders would be fine, alternatively pairs of
Cardan foils or wires.
Cardan type is a single short flexing element in tension.
Hope that this helps.
Regards,
Chris Chapman
