Tip & How-To about Watches
The"lead" in a pencil is graphite. This is commonly used in industry for lubrication in situations where there are high temperatures or pressures or where dirt would stick to oil. Around the home it can be used to lubricate where grease or oil would be messy, e.g.lubricating zips, drawing instruments, sliding surfaces, locks etc.To lubricate a zip simply run the tip up and down the teeth of the open zip.To lubricate a tumbler lock, first break off a lump of lead from a pencil. Push this into the keyhole of the lock. The aim is to crush the lead up into powder in the lock. Push the key into the lock and turn it backwards and forwards. If you meet any resistance just keep sliding the key in and out and backwards and forwards until the lead is broken up. Alternatively run the tip of a pencil backwards and forwards along the teeth on the key.Graphite can also be used for lubrication where a surface can become very hot and where oil would be unsuitable e.g. hinges on stoves, sliding parts. Make some graphite powder by splitting up a pencil using a knife or otherwise and extract the lead. Crush this in the lid of a jar with a blunt object such as the handle of a screwdriver or something similar. The powder can then be shaken into the hinges. If it is mixed with oil, it can be formed into a paste. This can then be worked into the joint or onto the surface to be lubricated.
