If you can afford the price of a cheap battery operated screw driver,some less than ten dollars and the tool that fit over your winder this costs one dollar and an electric tuner you can change a set of string in 5 minutes.Also when bringing your strings up to pitch with this screw driver bring the string up one note higher than necesary and by the time all the strings have been attached the first string youstrung will be nearly in tune.I carry this in my case all the time plus a pair of dikes to snip off the excess Louie Roy
