Alan,
The most economical method to get them close to equal tension again, is as described with the bungee around the wires. This is done (obviously) with main sail not hoisted, leaves both hands free to measure distance from the mast to each wire and adjust turnbuckles to make equal distance. Prior to, ensure the mast rotates freely and adjust shroud (sidestay) tension following diamond adjustment.
The other method is to borrow a Loos tension gauge. This device measures and gives you a numerical reading to compare each wire.
Now once your sails are up and your making fine tune adjustments you should be able to keep them close by counting turns (that's why I say borrow the Loos guage, they'll never be exact). Adjust your tension for the days' (crew) weight, wind (strength), and wave (choppy or smooth)...the three W's
John, thanks for looking up those old posts
