Apologies for not getting back to anyone sooner; I just found that book.
It's called "Race Car Chassis Design and Construction" by Forbes Aird,
published by MBI. ISBN is 0-7603-0283-9.

The basic problem in stopping racking (as it's called in table
construction) is in the bracing. I can recommend a couple of books on
car chassis design. Unfortunately only one comes to hand; I'll keep
looking for the other one (I'm building some bookcases and storage
cabinets for the Missus, and my books and magazines, which have got
somewhat out of hand... :-? )  

Racecar Chassis Design and Engineering, written by Forbes Aird.
Published by MBI in 1997. ISBN is 0-7603-0283-9.

The other book is something "Chassis Engineering"; it's a similar format
(8.5" x 11"). 

I heard good things about both books and got them some time ago, mainly
because I was thinking of a motion platform. 

I also an interesting site sometime ago for a motion platform based on
air-pressure. I believe it was supplied from a vacuum cleaner. I think
the person was selling the plans for about $40 (US, if memory serves). 

Hope this helps and I'll try and find that other book!

Jonas,
Don't even think of using anything ROUND as in piping - it bends far too
easy. Forget timber too. For a motion platform I'd use nothing less than
heavy square steel tubing or similar welded together - with
crossbracing.
The motion platform will have to move in at least two or three planes so
it
HAS to be extremely strong and rigid. Also your simulator is going to
end up
being very heavy esp. when you have two or three people sitting in it.
My
F-111 sim is very heavy by itself - I need a hydraulic car jack and
stands
to raise it enough to work underneath.
If you intend to use motion, you must also ensure that your simulator
frame\structure is sound. Again I wouldn't use timber. My F-111 has
timber
framing\ribs etc that are glued, bolted and screwed together firmly but
it
can still go out of shape even when I just wheel it around to reposition
it
! I found this out when I went to refit my canopies. The alignment was
out
on each by a good inch !!!
