Watch glass curvature

<p>Showing the curvature of the glass. I put this picture into blender and modelled an ellipsoid to best fit the watch glass. When I got the parameters I used these to <a href="http://www.mdmorris.co.uk/explore/photo/radius-top-section-match-curvature-watch-glass/">continue the curve in the top watch section</a>. I also used the parameters to make an ellipsoid brass die for squashing a copper disc to the same curvature, this is to be the dial.</p>
