Table size- 5ft wide, 12 ft. long, 36 inches  high to top of surface.
Surface Detail-  Aluminum plate surface with a  hole pattern 30cm. on
center.  Holes to be either 3/16 dia. or 1/4 inch dia.   suitable for
dowel pin registration of assemblies which  may be placed on the top.
The two arms will be placed opposite each other, 44 inches apart, and
31 inches from one end of the table.  The two television cameras will
also be mounted on the  table- loacted about 44 inches apartalso, and
60 inches from the opposite end of the table. The laser-scanner  will
be placed under  the table, with  the periscope part comming  up thru
the center of the table.

The table structure  will be a honeycomb type, using single sheets of
3/4 inch thick 5'  x12' grade AC Ext. Plywood  as the top and  bottom
skins.  These skins will be backed with a structure made of 2x6 clear
fir  webs set  on 12  inch centers.   Suitable inspection  and access
ports will be placed in the bottom skin to enable installation of the
arms  and television cameras  which require  bolting from  the bottom

The top surface plate  will be anodized  after punching and  reaming.
Color to be decided upon later.  Also, the material thickness will be
1/8  inch plate  or sheet type  6061-T6 Aluminum.   This will  be N-C
punched to  an  finished  dimension  which may  be  about  .001  inch
oversize to allow  for N-C punching tolerances, which  are claimed to
be  +/- .005 inches, but  in reality may be  better, as that includes
some allowance for  part alignment, and  also is maximum error  which
could  occur.   Closely spaced  holes may  be expected  to  have less
position error.

	The legs of the table will be wood, 4x4 Clear Fir, glued  and
screwed to both gussets  and a mounting plate, both made  of 3/4 inch
thick plywood.  Six  legs will be used, inset 6 inches from the edges
of the table.   And equally spaced.  Shimming  will be used to  level
the table once it is in place.

The Aluminum top  will be held in  place with a few  flat head screws
placed  around the edges  of the plate.   Also, all  unused dowel pin
holes will be  covered by  flat head acrews  screwed into the  T-nuts
mounted in the plywood plate  from inside the table.  Thus, each hole
will have a chamfer for the flat head screws, for about 1/3 to 1/2 of
the plate  thickness.  The  flat head, socket  head screws  will then
countersink flush with  the plate top, providing a smooth, relatively
hole free surface.
