Tied bass string, will it break?

[Richard Moody]

	I am servicing an Emerson upright from 1890.  In raising to pitch a half step(to
438 hoping for 435) , one bass string broke.  The first single going down in the
bass.  I tied it and have pulled it up to 1/4 step of its intended pitch.  However
the tuning pin resistance feels like it is ready to snap again. Am I being a
chicken, or will this string break?  (Core wire  #22+, tire wire, 22) 
	How many of you have tied bass strings only to have them break upon pulling them up
to pitch?
	Does anyone know if APSCO 24441 P.78  will fit?
