G'Day all I need some advice with the CCS system . As 1cent US coins are a bit thin on the ground down here I decided to use some OZ coins, because we don't use 1 or 2 cents any more I have had to settle on 5 cent coins. Now there is a weight difference between them with the Oz coin weighing in at 2.87 grams . So I have written a simple conversion calculator ,as you are probably aware when using 2 fixed weight you can't always achieve a perfect balance there will be some variation E.G, 60 U.S. cents = 150G -- 52 Aus coins = 149.24G will this sort of variation make that much difference

The CCS system would be more useful converted to some standard measure of weight anyway. Since it is about weight, there is no reason you couldn't do as you propose. As long as you have an accurate conversion from cents to Aus 5 cents it should work fine. Hopefully, someone will come up the the gram equivalent of cents and the CCS system could be gram based rather than penny based.

Sorry about the duplicate post

G'Day Drew the calculator does that it gives the grams in both currency's plus the variation between the US & Oz coins

At one point in time CCS data was being aggregated in a shared online database. This data is very useful to builders who needed an objective way to assess blanks that they had never built on.

Unfortunately, the CCS data available online is limited. How does a rod builder make use of that data if they have no basis for comparison? (i.e. have done CCS measurements on their own blanks or built on blanks that already had CCS data recorded in a shared database).

I realize my knowledge of CCS is limited, and know that certain CCS measurements depict how fast, relatively speaking, a blank might be. Nonetheless, I hope that CCS data can continue to be aggregated as new blanks become available. Isn't the basis for CCS to be able to compare one measurement with another?

This is not a criticism of the technique! Rather, it is a hope that CCS data sharing grows over time, ensuring that CCS will be used in the future.

try this: [northforkcomposites.com] with a small digital scale, no need to count coins

It will make a difference, the more coins the greater the difference.

If you can't get US cents, I'd move to pure weight and use that.

I don't know if this helps a lot, but 1 penny weighs 3.1 grams. If you need it in grains let me know. My email is unhidden. Hope this helps. I simply pulled one out of my pocket and measured it on my scale to get an average of a slightly used American penny.

Make sure the penny you weigh is post 1996. The weight is 38.61 grains.

If I remember correctly, a modern US one cent piece weighs 2.5 grams.

We use pennies that are post 96, but then we weigh the entire package (pennies, bag, clip) and then use the conversion chart on our website. I've brought a copy of the charts with me to High Point.

Thanks everyone you've given some food for thought
