And one cross-piece with handles:

Then one very long one like this:

The thing to do was to guess what they would make when put together.

Just then the Toyman arrived with three barrel hoops. And he worked away with his tools until the hoops were almost straight. Then he made little holes in them and nailed them with little nails, very neatly, on the four long curved pieces of wood. Then he fastened these curved pieces together by nailing the cross-pieces between. He fastened the other pair in the same way, and the affair began to look something like catamarans, those funny boats the geographies say folks use in Australasia.

But when he nailed the big board on and attached the steering gear, it was easy to see what all the time the Toyman had been planning to make. And when he painted the runners yellow with a little blue edge running around them, and the seat bright red, with a white star on it, they decided it was the finest bobsled in the world.

And, oh yes, he had to paint the word "Scud" in blue letters, right near the star.
