okay thanks for explaining all that. Could you please tell me about your set up that looks like a huge low gear on an older bike, love it! How does that older derailleur handle the big sprocket?

You will also need two chain whips to remove the outer sprocket.
This hub is similar to yours. I have built a custom cassette out of modern sprockets.
