This is very conservative for a 2 string bale I use the conservative rating of
R5-6 based on SI units. See the excell spreadsheet for more details.

I have also included a summary I found on the internet of some of the R

Anybody who wants these drop me a line and I will send then to you.

You can use my technical pages to do the conversion from imperial to metric.
