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
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.
