Full CCS Chart (From ERN/TP/PR 1 to 200)
Using info supplied by the creator of the CCS (Common Cents System), Dr. Bill Hanneman, I built this chart for North Fork Composites (where I have been assisting with some rod-blank development). I figured I’d post this for those FF&W readers who are into the CCS for blank/rod measurement. It’s the full chart of ERN/TP/PR values for the system all way up to 200. I tried to make it reasonably pretty, but with a bias toward “useful.”
If you know what this thing actually does, go get it (click on the chart). If you don’t know, but are curious, click here. If you don’t care, then just move along, there is nothing to see here… ;-)

Now that this thing is “in the wild,” the big question among the CCS-ers out there has become: HOW DO I READ IT?! I’ll get some proper visual aids up soon, but until then, try this:
The bottom of each blue grid shows the numbers of cents (or rolls of cents) used when trying to get any of the ERN, TP or PR values. Those values (1, 2, 3, 4, etc.) are shown in pale red next to the orange lines, which indicate the range of that particular ERN, TP, or PR value. The small bright red numbers over on the left side of the grids show the “tenths” of the ERN/TP/PR values (or for very powerful rods, as on the bottom grid, the whole number value).
For example, one may have used 41 cents to bend a rod to one-third of its length, and one wants to find the corresponding ERN value. One then looks at the grid where the “40″ cent value can be found, and moves over one grid unit to where the value would be “41″ (each unit is a step of “1″). One can then see that the value of “5″ (in pale red) starts right there (the orange line begins at that point). One can also see that on the far left of the grid, the small red number “0″ corresponds to that orange line starting position. That means that the ERN (or TP or PR) value is 5 + .0 — in other words “5.0″.
If the cents used to bend a rod to one-third of its length would have been 45, instead of 41, one would still look at the grid where the “40″ cent value can be found, but then one would move over five grid units to where the value would be “45″ (halfway between 40 ad 50). Moving up the grid to the orange line, one can see that it indicates an ERN (or TP or PR) value of 5 + .6 (the bright red numbers on the far left indicate .6 at that point). Thus the ERN (or TP or PR) is “5.6″.
And for one more…take a look at the top of any of the blue grids. See the “grams” (and kilos) values?” Let’s say you used 200 grams to bend a rod to one-third of its length and you want that ERN number. It works exactly the same as for the cents, just follow the grid line to orange line. Where they intersect gives you the value that you are after. So, 200 grams gives me a value (ERN, TP or PR) of 9 + .8. In other words, “9.8″.
Easy, right? ;-)
Hi Jason,
Do you use one third of the actual rod length or of the “effective rod length” i.e the length from the tipmost clamping point to the rod tip?

Tony.
Hi Tony—The short answer is “full length of the rod” (e.g. a 108-inch blank or rod is deflected 36 inches (one-third total length) to obtain ERN). I obtain my own ERN values using the “one-tenth” support approach—support the blank or rod for one-tenth of its total length (which in the non-metric system, can be anywhere from approx. 4.5 inches out to 20+ inches depending on rod type).
Hope that helps.
