 (See "conclusions 2003" at the btm. of this page for calculations I made before I realised

that the marks around the centrifuge were in fact 'in feet' *

(Written July 2005)

Seen around the circumference edge of the centrifuge set, are numbers marked 0 to 112.

*although they are regularly spaced, I had not been able to figure what 'units' the marked divisions were.... when it occurred to me to try Pi.(3.141)

 112ft. divided by 3.141(pi) =  35.65 ft.

The Divisions seen on the set edge are in feet (12inches)

and 112 ft is the circumference of the set floor at the marked points.

 (black triangular 'arrows')

The Centrifuge, at 'floor level' is 35.65 ft in diameter, and put another way the floor of the centrifuge if laid out flat, would be 112 feet long.

I came very close to this size a few years earlier, see below.


 Conclusions (Written 2003)

The 2001 novel Quotes 36 ft Dia. for the Centrifuge. The set itself, is universally quoted in 2001 'fandom' at "some 40 ft Dia". But across where? the inside (floor), the outside (under floor structure) or the  support structure......

There are unquestionably 48 tiles around the (floor) circumference.  The centrifuge was a real structure, (A studio set made at 'full size' or 1/1 scale) so by careful measurements of pictures showing the construction of the centrifuge set, I have deduced the following.

PICTURE: Floor access doors open    PICTURE:  pair of access doors open (open seen externally)   PICTURE doors open

The sub floor of the centrifuge Set is made from 8ft x 4 ft. ply-wood sheets....

The ply floor is made accordingly (from edge to edge)....... edge 2ft+4ft+4ft+17 inches, center 17 inches+4ft+4ft+2 ft edge...Plus 3 gaps of

1/4+ 1/4+ 3/8 inch  (for hinge clearance and central slot ) making a total floor width of  22ft. 10&7/8 inches... 

The slot 'doors' around the 'middle' are each  17 in.wide x  4ft 6 in long (54in)..... 

Each Floor tile is divided into 25 x15 small squares...with an equally sized border all around the edge..... (consequently the Tiles are effectively 27 x 17 small squares each)  

The floor is 6 tiles wide 6 x 17'' = 102 inches (8.5feet)   The floor is wider than this in several places, with 'borders'.......making a Max. width of 10 ft 6 inches..........

The 'narrowest' width is 2 tiles wide (plus a 2''  border each side)=17+17+4 inches = 38 inches (3ft 2'')

Two of these tiles will fit on to a single 'Slot' door ....2 x 27''=54''  

The floor tiles are 17 inches x 27 inches.... So consequently the small tile surface squares are  1 (one) inch square.

There are 48 floor tiles around the circumference, (and  24 access doors.)....


Hi res. drawings of the Centrifuge

Over a period of years, I have been working in collaboration with Dennis Gonzales of The 2001 A Space Odyssey Collectibles Exhibit.......Dennis is a very talented graphic artist, working for NASA !.....He has turned my centrifuge drawings into wonderfully detailed high definition renditions, the 'Definitive' Centrifuge'

Over 100 E-Mails of Photos, details, screen grabs, drawings, sketches, and lots of 'tweaks' have been exchanged between us. Below is the result.

Extra Information

The 12 'Light Panel Units' in the centrifuge, do not have their 'centre of radius' corresponding on the 'rotation' axis of the Centrifuge.....They 'Focus' at the 4 points marked with + in the picture titled. "Light units".....  All the Panels were made exactly the same, from just the One type of Mould....This saved having Asymmetrical Panels that do not 'Look right' and did away with the need to make glass-fibre moldings for a Left, Right, and Centre panel . Below are some pictures to show what I mean
