<br>
I think David Love counts himself as one of these fellows. I point you to
the following post made earlier in the present discussion... thats where I get
the figure of 25% remaining crown. Of course no one as specifically said
that such short ribs with such tight radii are pressed so low... but
glance at the post and you'll see where my querrie comes from.<br>

<br>
I'd agree with your last paragraph below... along with rib dimensions and
expected amount of residual crown after downbearing is applied.<br>
<br>
Cheers<br>

First of all, I won't question this figure simply because I haven't <br>
time to trawl the archives for a statement to this effect, but it <br>
would be good to have confirmation from one of the practitioners that <br>
this is so. It seems unlikely if I'm not mistaken in what follows.<br>
<br>
I think it would be useful first to have a true figure from one of <br>
the RCS-heads for the radius of curvature of the belly at a point <br>
where the rib is say, 1 metre long instead of the extreme cases given <br>
by Terry F. and Ron N.<br>
