Would like to replicate a worm but 3 times smaller.

So armed with the above information I have had a go at hobbing a worm wheel.
Then I set the lathe the cut the hob, 64dp which meant swapping the input gear for a 33t. The hob screwcut, then some cutting edges formed with a slitting saw. Couldn't find a piece of 8mm silver steel so I used a piece of printer rod, I haven't harden it as it was only a test;
Final test achived the magic 180t (gashed with a slitting saw) and a single enveloping wheel;
So all in all not bad, totally doable I reckon, I will now refine the hob in silver steel, harden then have a go in a piece of metal!
I think I will now take the time to do some drawings of the BCA, I might start a thread when I come to do my model for those who are interested.
Many thanks for all the input
