Breakfast Express - Toy Train from toilet roll tubes

Step 5 Assemble the wheels

" Pick a roll tube and pass the ear bud stick through one set of holes made in 1st step. For doing this, pass one end of the stick through the first hole, bend the stick slightly inside the tube using your finger and try to bring the stick out of the second hole
" Once the stick is out from the second hole using your fingers make the stick straight and centre it
" Pick a tea light candle pin and pass the stick through it. Pin tip should be inside and the flat circular side facing outwards
" Adjust the pin so that there is about 5mm of stick protruding outside the pin
" Similarly, fix a pin on other side of the stick [flat circular side facing outwards]
" Pick a bottle cap and pass it through the stick. Make sure inside of the cap is facing outwards
" Pick another pin and pass it through the stick, this time the pin tip is facing outwards and flat circular side against the cap. Idea here is to hold the cap [wheel] in place
" Adjust the pin so that the stick and the tip of the pin are on the same level
" Holding the tube firmly spin the wheel [cap]. If there is enough play between the 2 pins the wheel will spin smoothly. If not adjust the pins to bring in more play
" Similarly, fix the wheel on the other side of the stick
" Pick wire roll and cut 2 pieces of wire approx. 3 and pass these through the hollow bud stick
" Bend the tip of the wires on both ends to ensure they dont slip out from the hollow stick. This will ensure the pins dont fall out when the train is in motion
" Repeat above steps using other bottle caps to make rest of the wheels
