"No doctors and dentists don't use this particular drill okay? They have different types of drills."

His gaze drifted to Jake for a moment, "I am only going to say this once. Behave yourself whilst using the drill."


Moving back to his desk, Lawson picked up the power drill and held it up for everyone to see. "Okay so as you can see on the bottom of the drill is the battery. Moving up we have the trigger switch. This is button you press to make the drill go, as some of you have already figured out." He looked at Jake and Miranda as he said this.

"Up the top of the drill is the screw driver bit. As I explained before there are two types screwdrivers. Flat blade and cross head blade. Then we have the speed selector switch which I think is self explanatory. You have a choice of slow, medium and fast speeds. And over here is the reversing switch. Flick it forward and it pushes the drill in. Flick it back and it will go backwards, taking the screw back out."

He paused to take a breath before continuing, "This here is the torque adjustment collar. What this does is determines the depth you want to the screw to go in. The higher up the torque you go the deeper the screw will go in." And then he pointed to the last component on the drill. "This is called the keyless chuck. By turning the chuck counter clockwise it will release your drill bit, by turning it clockwise tightens the drill bit, keeping it in place."

Putting the drill down for the moment, Lawson placed a piece of wood onto his desk and then picked up a two inch screw. "Okay so as you can see I have a cross head screw, so I need to use the cross head blade. I now turned the chuck counter clockwise and then place the drill bit into the centre and then tighten the chuck again by turning it clockwise." He held up the drill so that the students could see what he was doing.

"Now that I have my drill bit in place, I need my screw which I have right here. What you need to do now is hold the screw against the piece of wood, pointy end down. Fit your drill bit into the screw and hold it steady and then place your finger on the trigger and the screw will go into the wood. Now because you are all beginners at this I want you all to make that your speed setting is on slow. Make sure your fingers are well out of the way when you get the drill going."

And now was the moment of truth. "You may all try it now."
