MT True-Scale Coupler Instruction Typo

MTL in the instructions for mounting BROWN TRUE-SCALE LONG SHANK COUPLER 001 25 301 (1301-10-B) states "Use a #56 bit and a 00-90 tap."

DO NOT FOLLOW THIS INSTRUCTION!!  It will lead to drilling a hole that is too big to tap with a 00-90 tap, in fact being larger than the tap cutter diameter.

The correct drill to use for a 00-90 tap is a #65 with an o.d. of .035"

Obviously a transposition of numbers, but could cause big headaches if followed.

Cheerio!

Gozer the Traveler. He will come in one of the pre-chosen forms. During the rectification of the Vuldrini, the traveler came as a large and moving Torg! Then, during the third reconciliation of the last of the McKetrick supplicants, they chose a new form for him: that of a giant Slor!
