Nail punch.
Stay out of the hammer lane.
You should take a hammer, put you Ipod on a very breakable surface, and then throw your hammer down on the Ipod with sutch force that you are blown into the next year
they should be about 1 foot above road surface.
large hammer because is has more driving force and the head is more far away from the pivot point (your hand) making it more powerful as you strike
Put some sand on it to increase friction!
Just something to add, if your replacing the rotors, damage by hammer should be of little concern. But DO be cautious of studs and other things in that area. Use lots of WD40 on the studs. Let it sit for a while. Get a rubber mallet or a deadblow hammer and strike the surface on each side. Never use a metallic hammer, it will ruin the rotor surface. Be sure not to hit the studs.
You should practice hitting the nail very slowly but with force. You cold also try wearing gloves for the extra protection.
Since it takes further to stop on a wet roadway you should slow down and increase your following distance
To break a brick painlessly over your hand by slamming it with a hammer, hold the brick securely on a stable surface with your hand underneath. Then, swiftly and firmly strike the center of the brick with the hammer. The force of the impact should break the brick cleanly in half without harming your hand.
What should you do before driving
The head of a carpenter hammer should be made of hardened steel for durability, have a smooth striking surface for accuracy, and have a slightly domed shape for better contact with nails. To manufacture a hammer head, the steel is heated, shaped into the desired form using molds or forging techniques, then cooled and tempered to achieve the desired hardness and strength. Finally, the head is polished and coated for corrosion resistance.
The magnitude of the force determines how deep the nail will be driven into the wood. A greater force will drive the nail deeper. The direction of the force should be aligned with the nail to ensure efficient driving, and the point of application should be concentrated on the nail head to prevent it from bending.
