Tools needed

• Screwdriver with drill (3mm)

• 3 Clamps

• 4 folding trestle legs

• 4 wood stripes

• Sandpaper

• Protective foil

• Protective cloves and work clothes

• Plastic bag (for paint tray)

Building Instruction

Step 1

• Wood sawing at the hardware store (Hint: please use straight wood)

•

Edit edges with sandpaper

Step 2

• Taping backs of boards (Hint: 750 ml paint are enough to paint everything twice if

the backsides of the boards stay untreated)

• Paint boards, scantlings and dummy with black paint

Hint: use a paint roller for smooth surfaces, allow to dry paint well, during drying times,

keep paint roller and paint tray in plastic bag – so both can be re-used.

Step 3

• Fix scantlings with clamps on the boards

• Pre-drill boards and scantlings

• Fix the scantlings with 2 screws to the board (Hint: let at least 10 cm from the outer

edge – this prevents bursting of the wood and there is enough space to mount the

hinges

• Secure board and scantlings with additional screws

• Fix scantlings with each other – 2 screws

Step 4

•

Fix the dummy border in the middle of board B (position see Fig. 1). It is there to

simulate a second FLL table. During the tournament there are two teams at a time

competing at two FLL tables fronting each other. Often there are mission models

being placed in the center of the top of the inner field borders

Step 5

That the table can be folded, the hinges have to be places at specific points. (Position

see Fig. 1)

• Connecting part A and B – screw the hinges under the board

• Connecting part B and C – screw the hinges on the scantlings

Step 6

• Attach draw latch on the outer sides of the scantlings over the joints, this stabilize

the table in unfolded form.

Hint: Put this table on the long edges, bring the draw latch under tension – 1–2 mm, lay

the wood strips on the floor while you attach the draw latches on the other side.

Step 7

The field plate is now finished. We wish you lots of fun practicing and tinkering!
