Every craftsman has his own unique way of doing things. Ask questions about a particular tool or method, and you may get as many different answers and suggestions as the professionals in the room. However, some techniques are more useful than others-here are some of the best techniques I know, from how to remove nuts from bolts, to how to (safely) find all the nails or screws scattered around the work area.

If the nut is stuck on the bolt, a pencil lead can be used as a lubricant. Oil will stick to the dust and cause residue to accumulate on the surface of nuts and bolts. But graphite-the material of the pencil lead-is a good dry lubricant and won't cause a sticky buildup on your parts. This method is also suitable for locks, door handles and fixing screws. Simply draw a pencil through the thread of the bolt or the inside of the nut, and then screw or unscrew the nut to the thread.

For the painless mace, please use a "finger protector" made of several different household materials. To secure smaller nails (such as veneer nails), you can use shredded cardboard or food container lids-just drill holes in the material with the nails you plan to use, and then pass the nails through the holes as a retainer. You can then straighten the nail with your fingers, a few inches from where the hammer hit. For larger nails, you can use a hair clip to hold the nails and keep your fingers clear.

Polishing multi-planar or curved surfaces can be challenging. Conventional orbital sanders or sanding blocks cannot reach all the positions you need to reach. For difficult narrow areas, you can use objects other than traditional sanding blocks to reach any hard areas that need to be smoothed. For corners and thin surfaces, you can wrap sandpaper on a tongue depressor or paint stirring rod. For the inside of the curved surface, you can use a pencil, screwdriver, or roller handle. For larger diameter curves, 3 to 4 inch PVC pipe or pool noodles work well. If you have difficulty placing the paper, you can stick it or use double-sided tape to stick it on the temporary block.

The jammed screws are really troublesome. If the screw head you want to remove starts to fall off, you can try placing a strong rubber band on top of the screw head and then pushing the screw gun through the rubber. Sometimes this will give you enough grip to move it forward. If your screw head is covered with paint, you can try to put the screwdriver in the groove on the head and knock off some paint with a hammer so that you can clamp the screw with the screwdriver. For bent screws, try to use a pair of vices to clamp the screw and turn it to remove it.

If you need to drill the hole to a certain depth and you don't have a stop ring, you can use a strip of painter's tape around the drill bit at the height you want to stop drilling. Give it some comfortable wrap so you can feel it hitting your surface. Please note that this method is not foolproof. If you work hard enough, you can go beyond your self-made stop loss, so it requires some skill.

To pull out the nail from the surface without leaving marks on the hammer, use a piece of wood, a piece of cardboard, or a piece of sponge to push it. Place the cushioning material between the hammer and the surface, and then use the claw side of the hammer to pull the nail.

To prevent the screws and nails from causing danger on the floor when they fall, use a magnet to pick them up. Of course, there are special tools that can do this, but in fact any magnet will do. Stick double-sided tape on the end of the roller or tie the magnet to the rope to avoid back pain. For easy disassembly, please use a ziplock bag or a piece of butcher paper between the magnet and the hardware. Remove the lid from the trash can or container. This technique can also attract metal shavings, so you must wear gloves to protect your hands.
