helical gear shaping

Interesting how it can produce the under cut :-) I'd be interested seeing s larger gear cut using this method

Yeah, I didn't film the cutting of that plastic "gear" 🤦‍♂️. But it worked the similar manner, so that cut begins at the one end and moves gradually to the other end. But brains will definetely overheat when thinking how this helical shaping works 🤯😂
