Repair of a single core plan? Absolutely!
The size of the beads will determine what size
needle threaded with wire to use.
Early planes used beads so large that you can re-thread t
hem with sewing needles!
Core planes are (were) often threaded without needles - there just
wasn't
enough room in each core for a needle once the first two (or three)
wires
were strung. The wire itself is the needle. IBM invented a very simple
solution - the wire to be strung was simply pulled apart gently. At the
break was a nicley formed taper.
