Eric,

Later in the day sheer occurred to me.
I will follow up w/ Don after I do my homework.
Yes, chemical and other tests can be done. Question is for what reason?

On the one hand you can simply look at these rivets and surmise that 
there is nothing particularly odd about them. They have been doing their 
thing for more than a hundred years. Balance that against repeated 
statements re: we have a budget for this investigation (undisclosed 
budget target), and in the walk-about a cost-benefit analysis sort of 
happens in the discussion. Up to that point of the walk-about the RFP 
was very diffuse in scope -- which caused us on our end to feel that we 
were wasting our time in responding at all (but good relationships 
prevailed and possibly what was actually happening was that a newcomer 
to an existing cluster of relationships was being brought into focus). 
Information, as you all know, can be costly. Sometimes the pursuit of it 
is not worth the cost. Once we had a clear idea what information was 
needed we were able to express how physically the desired information 
could be obtained with least cost and effort and we reduced the field 
cost on our part to a 5th of what we had been previously looking at. We 
also walked away comfortable and confident that we know exactly what 
needs to be done... that craftsmanship thing, obviously.

So, now I am curious if a timber peg works like a rivet, in tension and 
sheer?
