I picked up a parts stash last week and have a problem removing the derailleur cables from a set of Simplex DT braze-on shifters. The cable end seems fused inside the shifters. I've seen this before but usually a good shove/twist on the cable while holding it with some blunt nose pliers work.
In this case the cables eventually frayed and broke off. I tried pushing from the backside with a needle but it snapped and bent.
Does anyone have any tips / hints / techniques?
