[s-cars] Attempted Translations from Garrett to KKK Speak

[Bob Rossato]

Okay, okay, okay...

The numbers I get are:
Big diameter:  2.597"
Small diameter:  1.867"
Height of tall blades: ~0.860 (kind of hard to measure accurately as
assembled)

Though this was after 6-7 Guinnesses (Guinni?), so I can only guarantee +/-
0.002 accuracy at best ;-)
