... Yeah, Larry,..I've done it that way,..seems to be the best/easiest way...If there's enough slack,I've even cut back on the old BX casing and found the wires to be in perfect condition,like the day they were made...1800 years ago,complete with the beeswax cloth wrapping..I'm gonna try shrink tubing next,as I run into this alot,and want to find an effective way of dealing with it..
