No, I'm still on the first one. I doubt the rest will never be 
addressed, but I'd still like an answer to this one. If I ever get 
it, we'll try the next. If the crowned bridge supports soundboard 
crown, as you said, why do so many Steinways (with crowned bridges) 
have negative soundboard crowns before they even get out of the 
showroom? There is a fundamental contradiction here I'm trying to get 
you to answer to.

I also would like to know, how a long bridge supports sound board crown?

Again, I'm not discussing re-engineering. I asked for an explanation 
of a claim you made. It's very simple.

Agreed Ron, but nevertheless John, there is nothing wrong with 
re-engineering a piano if you;

a) have the skills and knowledge to carry it through and

b) if the resultant piano warrants to the effort required.

That just depends on the understanding and knowledge of the 
rebuilder. On the other hand, replicating the original techniques 
could be a complete waste of time and effort. Everything should be 
reconsidered. If the original idea is good lets do it, if there are 
better ways of obtaining equal or better results lets dump the old 
idea.

Of course. We all start out interested in the basics, which hopefully 
will lead to a pursuit of further knowledge, over an above the 
understanding of our forebears.  To recreate something in its 
original form, just as it was (warts and all), would seem to be 
nothing short of a wasted opportunity.

I would like to add in conclusion that, like Ron Nossaman, I have 
found the bridges do not need to be 'crowned' to follow the contour 
of a crowned sound board. Sure the long bridge will rotate backwards 
on its axis (from end to end) just slightly to accommodate the crown 
of the board, but it will be so minimal as to be insignificant. The 
rib profile,  'stress in extreme fibre' and paring profile is where 
its at!
