Week 4 – Do the Vehicles Move?

We are so pleased that our Engineer Level 1 entries move forwards and backwards. This wouldn’t have happened if we hadn’t have made the switches.

With a ruler, we carefully measured 25cm from one end of an MDF wheel to the other. Once we had made a mark, we added a metal drawing pin to either side. We carefully used a hand drill to make a hole for the wire connection to fit through.Mr Dougill helped us to attach the battery with a glue gun, before wrapping the wires around the metal pins.

With the second MDF wheel, we made sure the wires were connected to the motor. When we joined the wheels, we made sure the metal pins were on the inside. The, there we had it – a switch!

 

We tested the switch and our vehicles moved. We practiced moving the vehicles backwards and forwards and are very excited to test them properly!

Week 3 – The Gearing System and the Wheels

Our Engineer Level 1 entries are really coming together. Both the Bluebirds and the Mini Beans have attached the wheels and gearing system to their vehicles.

Firstly, we measured the dowel accurately and we made an axle. We attached this to the chassis, before carefully attaching the the wooden wheels. We made the gearing systems for both of the vehicles by using a hand drill. Once we had made the hole for the drive wheels, we attached an electric motor. The motor is joined to the drive wheel with elastic bands. We had to make sure that they were joined, ‘small to big’.

 

Next week we are making the shells for our vehicle… Watch this space!

Week 4 – Making the Vehicles Move!

After working hard to make a switch for the vehicles, both the Mystery Machine and the VW camper van move forwards and backwards! Here’s how we made the switch:

We had to carefully use a ruler to measure 25cm from one end of an MDF wheel to the other, carefully adding a metal drawing pin to either side. We then used a hand drill to make a hole for the wire connection to fit through. We used a glue gun (with the help of Mr Dougill) to attach the battery pack to the wooden wheel and wrapped the wires around the metal pins.

We repeated this process with a second wheel, but this time the wire connected to the motor. We joined the two MDF wheels together (metal pins on the inside) with a piece of dowel. There we had it – a switch!

We tested the switch and our vehicles moved. We practiced moving the vehicles backwards and forwards and are very excited to test them properly!

Week 3 – The Wheels and the Gearing System

Things are moving quickly with our Engineer Level 1 entry. We have attached the wheels and gearing systems on both the VW camper van and the Mystery Machine!

Firstly, we measured the dowel accurately with a ruler to make the axle. We then attached this to the chassis, before carefully attaching the wooden wheels.

To make the gearing system for both of the vehicles, we had to use a hand-drill to form the holes for the drive wheel. The drive wheel goes from the electric motor, to the center of the vehicle. We then use elastic bands to join the motor to the drive wheel: small to big.

Soon, we will have made the body to our vehicles! Watch this space..!IMG_0625 IMG_0629
