How to reverse engineer globoid worm gear

I need help in reverse engineer worm part of a globoid worm-gear box.As i can't find any good calculation charts for this kind of a worm gear - I'm sure that lot of future engineers would benefit from this question - tutorial.

I provide snapshots of this small worm gear - with dimension scale for scale purpose.

ps. if i find a way of doing it -ill post it here in form of tutorial.

Thank you in advance!

Hm.. i will watch the video to see but i don't have the problem modeling the worm gear , i have the problem measuring the real life worm gear and finding adequate equations to recalculate new one (this one has damaged teeh, used up worm etc. )
