Typical Lego sets provide a free-wheeling, imagination-run-wild construction experience. But, Lego construction sets, such as the Lego Road Roller set 30003, direct users to build specific and customizable replicas of heavy equipment and their operators. As with other Lego construction toys, the simplicity of its parts makes the assembly process a basic yet educational experience for young children.
Assemble your construction worker. Snap the blue torso section into the blue leg piece and then attach the yellow head and red hat.
Assemble the side pieces. To each long, thin, 1-by-8 yellow piece, attach a black "plus" cylinder at each end. Over each cylinder, attach a gray nut. Then, place a large gray roller wheel on each cylinder, followed by a second nut.
Connect the two side pieces. With the wheel loader sides facing inward, attach the center circle of each side piece's yellow base to the gray 2-by-4 piece. The wheels from the two side pieces should now be flush against one another.
Attach the flat, black 2-by-6 piece between the two sets of wheels. Centered and on top of this piece, place the yellow brick that has the lowered 2-by-2 center section. Its upward extensions should be over each set of roller wheels. This creates the seating base.
Attach the safety light. Snap the gray pole onto one side of the roller's back end. On top of the pole, attach the orange lamp piece.
Attach the seating and controls. On the rear extension of the yellow seating base, attach the yellow seat-back. To the front extension, attach the steering wheel. At the back of the center depression, attach the flat, gray 1-by-2 piece. On the front of the center depression, place the 1-by-2 black grill piece.

Making ammunition is a hobby or business that can easily be done out of your home's garage or other area that has a concrete floor. Bullet casting machine requires certain types of equipment that must be gathered with safety in mind.

Get the first piece of equipment that you must have for bullet casting. Precision melting pots come in either electric or gas. Gas melting pots usually come in the form of a furnace. This keeps your lead melted so that you're able to cast your bullets.

Find a good ladle as an important piece of equipment for bullet die casting. Your ladle is used to pour the melted lead into your bullet molds. These ladles need to be well-insulated on the handle end so that you do not get burned.

Decide what type of molds you need for bullet casting. There are single bullet molds or multi-bullet molds. Check to see that you are getting the correct caliber of mold for the size bullets you want to cast. You must also get a block of wood to knock the bullets out of your mold once they've been cast. The wood prevents damage occurring to your mold.

Acquire the right type of safety equipment for bullet iron casting. A fire extinguisher is a must when you are melting lead. Always wear safety glasses to protect your eyesight. Splattering lead can damage or destroy your eyes. Wear a long sleeve shirt. It's better to burn a shirt than to have hot lead penetrating the skin on your arms.

Sing a cutting machine for casting concrete floors gives the finished product a professional look. Power trowels are used for both floating and finishing concrete floors. Compared to hand trowels, power trowels significantly increase the productivity and quality of the finished product. They come in walk-behind and riding models, and they are quite expensive. However, consumers can rent power trowel machines from tool rental businesses for a reasonable amount, and then they don't have to worry about the large expense or upkeep of the casting machine.
Instructions
Procure a power trowel machine. Unless you can buy or borrow a power trowel machine, rent one from your local home improvement store. Read the machine's instructions because you don't want any surprises once the concrete is ready to set.
Prepare the area. If the floor requires any wooden forms before the concrete is poured, make sure your forms are in the correct positions. Brace the forms securely to avoid frustrating mistakes later on. Make sure the floor is reinforced according to local regulations.
Determine how much concrete you'll need by measuring the floor and multiplying the square footage by the depth of the intended floor. Add five to 10 percent to account for losses or spillage.
Pour the concrete evenly on a cool, humid day. If you pour it in hot, dry weather, it will dry out before it cures properly. Have several helpers available to help you rake the concrete evenly over the area for the floor. This should be done quickly. Using a side-to-side motion, rake it evenly over the form.
Use a bull float to float the surface and remove air bubbles from the concrete. Push the bull float away from you across the surface until the entire surface has been worked.
Wait until the concrete has cured enough that you barely leave a print on the concrete when you walk on it.
Before starting the power trowel machine, check the stranding machine for gasoline, oil and water levels. Wear safety glasses and a dust mask, and make sure that onlookers stand at a safe distance from the machine.
Connect the battery wires. Make sure you read the operation manual for instructions specific to your model.
Run the machine across the surface of the concrete, overlapping rows, until the entire surface has been smoothed and is completely level. If you desire a non-slip surface, you may need to roughen it up after you are done with the trowel machine.
Clean the concrete off of the power trowel machine with water. An old paint brush can help to loosen concrete that has started to harden. Never get water on the engine while you clean the machine.
