New Zealand's beekeepers use a range of frame wiring jigs, involving 
some form of compression of the end bars.  My preference has been the 
cam that Joe Mc Cool refers to.  And when used properly, wiring 3 
wire full depth frames can progress at est 50 per hour without too 
much strain (so to speak...).  More troublesome than any worry about 
the outermost wires is the problem of soft wood, and the wires 
cutting into the end bars (not many here would ever use eyelets that 
I have seen for the purpose).

And my experience is that it is easier to put heat to all the wires 
(wire in fact - just one long wire...) at once, with the wire above 
the foundation, letting it melt its way down in, then maybe touching 
it briefly to finish off embedding any piece that hasn't fully sunk 
in.
