WOW!!!!! This definitely the best thread cutting method I have seen and as a bonus it looks like it will be "fool proof". (Great consideration in my case)

Yep, that was the one I was linking to.

Great Youtube link, thanks for posting it. I think the problem with the McJing cutter is it's shank dia. of 3/8".
I will have to check my collet sizes. I have seen a car inlet valve with teeth ground into the outside dia. and presumably a rough clearance ground behind the teeth used as a cutter for box making. The stem was cut down to a suitable length, not sure how lucky you would be in getting a valve stem with a suitable diameter to suit a router collet. Would an electric drill be fast enough to drive the cutter?

Anyway, a great thread, thanks for starting it,

He used a Jacobs chuck ,but I'm pretty sure I can machine it down to 1/4" o(r persuade a mate in the club to do it for me on a metal lathe) couldn't quite justify $1200 for a mini metal one that Dave was flogging at Turnfest lol

Done Cheers!

Scotty, Carbatec used to sell one for threading on woodlathes, not sure if they still do as a spare part. It had only 2 teeth.
