Nifty thread cutting technique
I thought it was going to be something complex or complicated - the DOC is pretty impressive by itself

Just doing the math on this and for those with more discrete dials, perhaps metric, and smaller machines taking less material per pass setting a ratio of 10:5.6 or 100:56 on infeed versus compound feed yields 29.24 degrees.
So if I was taking 0.25mm cuts I'd advance the compound 0.14 - it also makes it easier as my compound leadscrew has a lot of free play as it is currently, I'd only need to be advancing it, not in and back out, then back in with the occasional overshoot...then rinse repeat

That type of method is nothing new.

It's not a bad idea, that had never occurred to me - same overall result as setting the topslide over 30deg.
