[pianotech] bridle wires

[David Nereson]

    Has anybody replaced the "stupid"-type bridle wires (where 
the strap can slide down the wire if the hole in the tab gets 
enlarged) on some Baldwin verticals with "real" bridle wires? 
What's an efficient way of pushing the new ones in (into the 
same wippens)?  The new wires have fluted, not threaded ends. 
I'm wondering if it can be done without unscrewing all the 
wippens from the action.
