I know I could get a rough idea by munising the radius of my head tube and seat tube, but this does not seem very exact.
Suggestions welcome!
Cheers

Just plug in the numbers and it does most of the work ... as this is demoware only, look for free stuff on uTube, etc., that does similar functions. If looking for technique, the Medford site has a free pdf file re tube notching 101 that covers a lot of helpful ground.
If shopping for tools recommend this one in particular:
