Neil,
The horn in the TR6 operates as follows:
When you push the horn button, you energize the horn relay, which closes
the relay contacts. When the contacts close, the horns sound.
If the horns don't operate, the fault is either the relay, which if it
operates you should hear click; the horns themselves; the wiring which
ties it all together; or the horn button on the steering wheel (including
the button tube inside the wheel hub).
You mention that you change the rotation position of the steering wheel,
do you mean that you turn the wheel, or that you turn the horn button?
The horn button has a contact on it, and if you turn it, it won't come
into contact with the sleeve in the hub.
You also make mention of grounding it with a screwdriver. Ground what?
