[Public-List] dye-penetrant - NDT engineering inspection

[David Terrell]

My rigging was original and so was about 38 years old when I replaced 
it. I used Riggingonly.com in Mass and got good work as well as a good 
price. I have a friend who runs the lifts at Alta in Utah - in charge of 
maintenance, replacement and operation of the whole lift system - and he 
immediately noticed that the rigging was new when he came sailing that 
year. The advice to ditch it if it is old seems best to me. Documenting 
the change with the insurance company makes a lot of sense as well.
