Re Dickerson 8012 Taper - Lee Koch

Hi John - I think I can reply for Dennis, as I was one of the guys who 
measured those rods.  Ralph Tuttle did the actual spreadsheet work.

In the upper left corner, in blue, you'll see the real measurements we took, 
for all 3 flats at each measurement point.  The 3 flats got averaged and put 
into a column in the center of the page.  (There is a table of blue numbers 
for each rod section)

To the right of that you'll see there is a column allowing for varnish.  The 
thickness of varnish of course was just our guess.  The long column to the 
right of that is what we think the raw cane would have measured, subtracting 
for varnish, and interpolating between our measurements so as to put 
everything back on 5-inch stations.

The last page shows our interpolated numbers, on 5 inch stations, with 
varnish already subtracted, using both the Howell method (measure stations 
from the butt up) or the "classic" method (measure stations from the tip 
down.)  That's the "raw cane" numbers.

So the data exists both ways in the spreadsheet.  If you're willing to 
accept our assumptions about varnish thickness and how to interpolate 
between measurements, then the table on the last page is the one to use.  If 
you want to adjust for a different varnish assumption, or if you want to 
interpolate differently, then our actual measurements are there for you (or 
anyone, of course) to do so.

Hope this helps,

Lee
