1) Measure the width / diameter of the axle
2) Draw the marks on the plank indicating the center of the plank and the width / diameter of the axle
3) Make the axle retainer by several sealer tapes:
  1. one short sealer tape with its sticky side facing the sticky side of the middle region of another longer sealer tape
  2. attach the longer sealer tape to the plank (centered)
  3. two same sized sealer tape wrap around the longer sealer tape (as close to the rim of the axle as possible)

Note: The axle may be placed at the center of the plank to assist positioning

(a bit = from 0.5cm to 1.0cm)
2) Trim the axle to the appropriate length
