Yes, I do need the inch by inch interpolation. The fly rod's action, depends heavily on getting the numbers over the length of the rod spot on to the cross-sectional dimensions calculated. Little differences at different points in the taper can make huge differences in the action of the rod. It really does need, and really does depend, on the taper cross-sectional dimension at each inch in order for the taper to do what it was intended to do. There's a lot of cantilever beam theory that goes into creating the taper, and the numbers work for a given station along the X axis. Stretching it out and making the machine interpolate the cross-sectional dimension over a greater difference between the X stations would, and could, give you a completely different taper, changing the action of the rod, and also possibly changing the line weight required. > This same idea could enhance the accuracy of my lathe too. :) > > Cheers, Gene Heskett > Cheers, Mark ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
