Thank you for posting this. Also, if this forum is capable of hosting the file and if anybody is interested, I have a Excel based spreadsheet file that does the calcs for you. You just plug in the variables like sprocket and wheel sizes, RPM etc, and it spits out the answers.

If you upload the spreadsheet onto a file hosting site and give me the download link, I can post it as a note on the Facebook page. All credit will go to you, of course.
