Decorative Wall Clock
Students will design a clock and make a wall clock from scratch using wood, a bunch of nails and thread.
- Draw the clock design
- Decide the dimensions of the clock
- Select a piece of discarded wood and arrange it to shape the base, cut if necessary.
- Use sanding paper to smoothen the surface
- Locate the center
- Draw the circle using your creativity
- Draw the outside shape
- Start hammering the nails on the outer drawn path, with 0.5cm distance
- Count the total number of outer nails
- Calculate the circumference of the circle
- The distance of the nails on the circle should be proportional to the outer number of nails, eg: 1:3, 1:2 or 1:4
- Drill a hole at the center of the wood
- Attache the clock machine from behind
- Smoothen the surface if necessary
- Start looping the thread from outer to inner following the calculated ratio
- Attach battery and test!
It is very important to follow the calculated ratio for perfect results, otherwise, the threads will not proportional and the extra loops on certain nails will be visible once completed, and it will not have a fine homogeneous look
