Where it goes
The boards
Every size in millimetres, from one plank 150 wide and 15 thick.
Front
205 × 150 × 15150 wide, 205 high, 15 thick, with a hole 25 across.
Across the front, on the bench. The middle of the hole is in the middle, 155 up from the bottom.
Stuck?Show a hint
The Circle tool takes the radius, half the hole: 25 ÷ 2 = 12.5. A shape on a board's face, pushed as deep as the board is thick, cuts a hole right through it.
