Now imagine I remove the tube and cut the object so formed across both ends at an angle of 25 degrees to  the axis of the semicircular surface to form a chute with vertical sides, vertical ends, and a semicicular chute surface at an angle of 25 degrees to the vertical. \r<BR>\n" );

document.write( "In this case how can I precisely quantify the dimensions, and in particular specify a design plan for both the finished object and the cutting template for a piece of sheet metal that could be bent into the desired shape? In the template of the flattened opbject, what will be the angle between the four lines that will form the vertical ends of the completed chute (the ends of the two sides), and how can I specify the arc between them (semicircle in the final object, but arbitrary arc in the template)? I think the arc will still be circular, is that correct? (In which case it will be defined by the radius, the angle between the two lines, and the location of the centre of the arc).\r<BR>\n" );

document.write( "Reason for the question: I need to make plans for a modified coffee grinder exit chute, from which someone can construct the part for me. The original chute is horizontal, the coffee grinds are pushed out in large clumps and then fall through a tube - not surprisingly the result is very poor. My aim is to make a new chute that falls at a steep slope right from the start, to prevent clumping.\r<BR>\n" );
