measuring lifelines ?

[Brian Duff]

ahh, but with lifelines you have to deal with bearing points-not pin centers, and then there are the gate eyes, pelican hooks and the like, so a side might have 3 or 4 very important measures. I bring all this up as part of a dispute with a supplier.

He agrees that my way of measuring is the standard, and that it was their mistake, but am I really right ?

this industry would be so much easier (perhaps less rewarding, but easier) if there were published standards of how to do all this stuff. The RA is great, but we need a real nuts and bolts manual similar to Nigel Calders book, even more technical. I guess I'd better get writing (yeah!)

so I am here hunting more input
