If I order my st20y with 24 (half index?) station turret, am I able to use the dual output live tool holders to have potentially 2-4 (2 main, 2 sub) holders per live tool drive?

Link to some holders for reference.

RADIAL SINGLE-SIDE TWIN HEAD DRIVEN TOOL IN Y-AXIS – MD Tooling – Precision Live & Static Tooling
AXIAL SINGLE SIDE TWIN HEAD DRIVEN TOOL IN Y – MD Tooling – Precision Live & Static Tooling

Is this something that is called via a tool number and thus easily used with cam programs such as fusion easy?
 
Those you wouldn't use a half index for. Just setup those tools with y-offsets, along with x and z of course.

And make sure your post spits out a Y-value on the approach move so it can apply the offset. I have mine to go Y Z first, then X. Changed that a long time ago, before I got my live tooling stuff setup. Very easy to keep static tools on centerline that way. No shims needed!
 
Yes, you can use the multiheaded live tools. If you have multiple tools in the same station, you use the same tool numbers but different offset numbers.

The half indexes are only for turning tools.

You can use double turning tool holders on a Y-axis machine without half indexing, but I when I ordered our ST20Ys, I spec'd ours with it anyway. Half indexing provides better part clearance between turning tools and is slightly more error proof. The option includes some half-index holders, which helps offset the price premium. Time will tell if it was worth the money.
 
I've not run a y axis lathe, how do you call different y and z offsets for same tool number?

T (tool number) (offset number)

T0101 = tool #1, tool offset #1

You can use whatever offset number you want. T0138 is tool #1 with offset #38


I made a triple Ø1" od holder for drill/c'sink/tap. Code like this:

Code:
N12 
(DRILL 5MM FOR M6 TAP) 
G99 G80 G40 G00 G18 
G0 G53 X-.10 Y0
M1 
T1222 
(TOOL #12 OFFSET #22, Z-MIN: Z-.4252)
G97 S760 M3 
G0 Y0 Z1. /M8 
X0 
G83 G99 Z-.4252 R.05 F.005 I.25 J.05 K.08

Makes perfect sense. Thanks for the explanation and sample code! I understand what needs to happen now. I still plan to get half indexing for turning, I want to be able to easily call as many tools as possible. editing a post to allow for difference offsets should be doable.
