No but it's something I'd love to bottom out at some point soon. I can't sensibly rigid tap on my Acorn machine due to the need for a directly connected spindle encoder which isn't really practical on a turret mill.

I have a Tapmatic clone, so that would be a pragmatic compromise. If you plan to have a go, I'd be interested to see how you get one and might be provoked into joining in for the ride.
