I don't think it is possible to get any form of indexing working the way you describe and I am pretty sure from memory that positron levers had no friction mode either as they used a solid wire rather than a cable.

Thanks Kermit- your memory serves you well. The indexing comes from the derailleur but The Positron lever is all I want to keep, I've attached a conventional cable to the shifter,
So all I want it to do is friction shift.
The problem I'm anticipating is that the Positron lever might not have enough pull to move the mech through the 6 speed uniglide cassette.
If that was the case I might have to cut the plastic on the shifter to get more pull.
What I ideally need is some info on how much cable a Sachs rear dérailleur would need to pull through a six speed uniglide cassette.
