3.1 Power tools

There are many types of power tools. All brands also have their own types and colors. The photos in this chapter are therefore an example. It can prevent machine needs to work.

Follow the following 8 agreements every time you start working with power tools.

 

Rules  Why?
1. First remove the plug from the socket when you need to change a drill, saw or milling cutter. You concentrate on changing the drill bit, saw or milling cutter. You can accidentally press the power button. This is dangerous, because you can injure your hands and fingers.
2. When you need to set up the machine, unplug it first. You concentrate on setting up the machine. You can accidentally press the power button. This is dangerous, because you can injure your hands and fingers.
3. Check the cord. Will not work with a machine with a broken cord or plug. You can get a power surge and a short circuit can occur.
4. Clamp the workpiece securely to the workbench. For example with a glue clamp. Usually you need both hands to hold and operate the machine.
5. Make sure you do not drill or saw in the workbench. The workbench should last longer.
6. Always carry the machine cord over your shoulder while working. This way it doesn’t get in the way and you can’t accidentally saw through it.
7. Do not make rough movements when working with machines. Also, do not use more force than necessary. Do the work slowly and gradually. It is safer and you get a better result when you work quietly.
8. Always wear hearing protection. Working with machines is bad for your ears. Protect your ears so you won’t be deaf in 10 years.

3.2 The chisel sharpening machine

What can you do with a chisel sharpening machine?

How do you use a chisel sharpener?

  1. Set the leaning tool that the chisel rests on to the same skew as the crease of the chisel.
  2. Check that the grinding stone is clean and can rotate freely.
  3. Check your own safety. Don’t have loose clothes, cords, jewelery or hair that can get into the machine.
  4. Start the machine.
  5. Place the chisel on the leaning tool.
  6. Gently push the chisel against the sharpening stone. Sparks are generated during sharpening. In principle, these are not dangerous.
  7. Gently move the chisel back and forth along the sharpening stone.
  8. Cool the chisel in water regularly. This way you ensure that there are no blue burn marks on the chisel.

 

Sharpening on a chisel sharpening machine creates a burr at the crease of the chisel. After sharpening, you must therefore ‘sharpen’ the chisel with a whetstone.

  1. Moisten the whetstone.
  2. Wet the back of the chisel with a twisting motion first.
  3. After that, turn the chisel over and also sharpen the crease of the chisel.
  4. Repeat this several times.

Sharpening and honing a chisel is a skill that you have to practice a few times to get the hang of it.

You have to make sure that the right drill bit is in the machine. Because a drill bit to drill a hole in the wall is different from a drill bit to drill into wood.

How do you drill a hole?

You can poke a small hole in the wood with an awl. That’s where you put the tip of the drill. Keep the drill straight. Don’t press too hard yet. Turn on the machine. Then drill the hole. Do not do this too roughly or too hard, otherwise the drill will break.

If you need to drill a deep hole, back off the drill a few times as you drill. This will allow the sawdust to drain out of the hole. This retrieval of the drill is called ‘unloading’.

3.5 The Jigsaw Machine
What can you do with a jigsaw machine?
With a jigsaw machine you can cut round or curved shapes from wood or sheet material. The jigsaw is electrically powered.
What does a jigsaw look like?
At the top is the handle with the on/off button. There is also a stop button. This blocks the on/off button so that you can release it during sawing. This works better for you. The saw is at the bottom. The saw goes through the base plate of the machine. You can usually mount a vacuum cleaner hose on the back of the machine. When you turn on the machine, the saw moves back and forth quickly. The saw makes a sawing movement from top to bottom and back. With a switch you can make the sawing movement larger and smaller.
How do you use a jigsaw?
If you hold the saw by the handle, you can easily reach the on/off button. You press the base plate onto the wood while sawing.
  1. Draw the line you want to cut out on the wood.
  2. Place the tip of the base plate on the wood.
  3. Make sure you keep the saw exactly behind the line (the saw must not touch the wood).
  4. Then turn on the machine.
  5. You can press the detent button during sawing. You block the on/off button that you don’t have to hold down. This works better for you.
  6. Slowly move the machine forward.
  7. Blow the sawdust away each time to keep seeing the line.

 

If your saw bounces and it is difficult to keep cutting along the line. So take it easy!

 

Turn off the machine before pulling it out of the wood (or pulling it back).
