David, best way I know to get the Cplane correct is to set the Cplane at each face with two right angle lines that form the correct Cplane. Select X axis first then Y. It's easiest if the lines intersect at one endpoint but not mandatory. It is a more bulletproof method than selecting named Cplanes for me.

What's the old name, NewName?
LEDs... Now you're talking changes in tech. Won't be long and LED arrays will be replacing incandecent and flourecent bulbs for general illumination. This will have a dramatic effect on energy consumption. Of course population growth will offset the LED reduction, but it's still a good thing.
To make it a bit simpler to think through, forget about the helix thing and just think about the row of tooth points 1 pitch distance apart touching a line. Then move the whole array of tooth points some distance and see what you get.
EG. 1TPI= 1" tooth point spacing, think about 3 teeth numbered 1,2,3 from left to right. the bottom of the hole is on the right.
If you linear feed the array of teeth left 1" through a helix, tooth 3 will move directly into tooth 2's start point.
If you linear feed 2" through the helix, tooth 3 will end up in tooth 1's start point.
The difference between this and starting 2 helixs 180 degrees apart is that if the bottom of the hole is to the right of tooth 3, the screw will bottom out at tooth 2 start point.

I don't have time to try but I think your 2X feed idea would work. However, the 20 degree included thread angle is working against that because you'd need 2X the normal side clearance angle and the correct tooth form would be extremely fragile.
Dude ain't asking for much, is he?
One pass creates one helix.
For double lead you need double heli. Hmmm...what's plural for helix?
Oops... After more thought, I think you might be right! The angle of side relief on the cutter might limit feed rate though.
Are you going to try it?
I remember the article too dOOd. I think I have it on email at home.
Of the many people murdered in Spain, I think its safe to say that virually none were directly responsible for the murderer's grievences. The murderers are simply the vilest of humans on the planet.
President Bush is a fallible human leading other fallible humans against the vilest of humans. That's going to be dirty business, but it must be done.

Google search "form tap drill chart".
Not yelling at you for not trying it... I just can't belive it worked. Is Google good, or what?
Thanks for the demo, Dave.
I hope you sell them by the bushel.
If any of you Integrex guys are interested, I'd like to correspond a bit so that if possible we can submit improvement requests that will be complimentary rather than conflicting so Dave can offer a better off the shelf product with broad appeal for Integrexers. And hopefully save a customization buck as well.
Tweek on.
Macro programming is algebra with funny looking variables. You have to work at it to get it. The machine will judge your work, but never tell you the correct answer.
One of the post guys needs to jump in.
You need to go from A-93.731 to A-229.313 in way fewer increments. Looks like you are in degree/min feed. Roughly converts to 15 in/min at 1" radius.
Check the switches for breaking up A moves.
