Calibration of your rig tension with SureCheck - 7 mm.

You can adjust the shrouds with the folding rule method but a more easy way is to use a rig tension meter. The only problem is to buy one since most of the tension meters cost a lot of money. Today I have bought a cheap swedish made tension meter and I show how to use it. note : If the turnbuckle squeaks stop tightening - this is a sign of over-tightening and poor lubrication. You can get the tension meter in 4 different sizes : 2.5 - 4 mm. wire - 77 US Dollars 4 - 6 mm. wire - 86 US Dollars 6 - 8 mm. wire - 90 US Dollars 8 - 10 mm. wire - 103 US Dollars Bluewave smartpin : VP1020 : 1/4" VP1225 : 5/16" - 3/8" VP1632 : 7/16" - 1/2" VP2340 : 5/8" - 3/4" price around 26 US Dollars, possible to buy at svb.de
