Tigers,

Luckily, we do not have to guess at the origin if the Tiger steering 
design, and the Ackerman Angle.

In 2002 The Tiger's United meet at Mammoth Lake had a guest speaker, Mr. 
George Boskoff.  George was working for Carroll Shelby, and was given 
the assignment to take an Alpine and make a Tiger out of it.  That was 
about the limit of the "design criteria".

As George tells it, he put it together with no engineering, or technical 
instructions, other than "get it in!".  When it came to the steering, 
the he chose a rack mounted to the front suspension cross member to get 
around the block, but the connecting rods from the rack to the steering 
arms were straight, and would not connect to the steering arms, which 
were much further back.

At this time Carroll was off in Detroit, with his chief engineer (who I 
am led to believe had little to do with the Tiger project), negotiating 
another "big deal" with Ford.  When he returned, George said he asked 
what he should do with this mis-match.  Carroll (known for his driving 
and marketing skills, not his engineering expertise) told George to just 
bend the arms back so they would fit.  "But the Ackerman Angle will be 
all screwed up", George advised (as he tells it).  Carroll's Chief 
Engineer was not involved (we are told) in this project, and neither was 
Ken Miles.

"Just do it",  was Carroll's reply, "we have to ship it."  So, that is 
what George Boskoff did, and Rootes never changed it since it worked 
(sort-of).

That is how George tells it.  Many were present at the dinner and heard 
the talk.  I have the video of the entire presentation, and live 
witnesses to the event, in case you think this is a "tall tale".

Now you know how we got to where we are.  Through schedule based 
engineering, and British design review "It works, don't it?"

Now THAT is the documented truth, as related by the man who did it.  
George attended yet another Tigers United event, this time along with 
Carroll Shelby.  Don't think this matter was discussed, but wasn't there.
