Quorn Tool and Cutter Grinder, part 1A, spindle housing

[Toolmaker51]

I'm fiddle-farking my laptop right now, preference of a wallet sized card, maybe RH one side, LH on reverse. A Machinery's Handbook sized insert sounds good too, like a bookmark. Working with flow-chart style might as well been spaghetti....color coding comes to mind, even worse.
Looking first to clarify readability with font, spacing and size combinations. So far, it's Calibri; the code letters in bold, one extra space and 2pt larger than text. But a screen shot works on anyone's phone, save Marv's candle-stick or hand crank phone; Hello Central?

Hey Jon; how does one post a word file, from PC? This version isn't exactly as described above, editing in place.

A - Threading tool upright, point toward lathe back
B - Threading tool inverted, point toward lathe back
C - Threading tool upright, point toward lathe front
D - Threading tool inverted, point toward lathe front

L - Direction of feed = Left
R - Direction of feed = Right
f - Forward Spindle Rotation
r - Reverse Spindle Rotation

To Cut Right Hand External Threads: L f (A/D) R r (B/C)
To Cut Left Hand External Threads: L r (B/C) R f (A/D)
To Cut Right Hand Internal Threads: L f (B/C) R r (A/D)
To Cut Left Hand Internal Threads: L r (A/D) R f (B/C)

To help visualize, this uses conventional toolpost in front position, OR rear position for "tool point toward front" descriptions
