METAL FATIGUE AND HOW TO SPOT IT
Fatigue failures are among the most common causes of problems on yachts, particularly the standing rigging of the mast.Fatigue can affect almost every part of the rig, including chainplates, turnbuckles, swaged fittings, the cable itself, the T-balls or stemballs swaged onto the upper end of the cable and the fixed mast plates or tangs that connect these fittings to the mast.Inside this Metallurgist Vyv Cox shows how strongly-coloured dyes can be used to reveal fatigue cracks in rig components.
