Step 4: Make the bike axle notch
In the end of the 500mm ‘Main ‘A’ strut side B’ drill a 10mm hole in the middle of the strut, around 30mm down from one end.
Cut from the top of the strut down to the edge of the hole on each side using a hacksaw, to make a slot and then file any sharp edges. This is for the back bike axle to sit in. The nut on the back axle will be loosened at this point to fit into the slot and then tightened up to hold onto this slot.
Also drill a 10mm hole in the same place on the 650mm ‘Main ‘A’ strut side A’. This will be used to hold the box section nut holder on the other side of the back bike axle.
Cut the end of the 500mm strut across at an angle of around 30 degrees. This is because the bike frame (when attached) will hit into this piece of metal if it is not removed.
