- Wooden oak board
- Keyhole hanger (incl. screws)
- Piece of wood cut in 60 (or 30) degree angle for measuring positions of hour markers
- Raw linseed oil (Be aware that rags used for applying linseed oil can spontaneously catch on fire, so make sure to dispose of them properly)
- Straight router bit
- Round router bit
- Fine grained sandpaper
First I cleaned up the board using a sharp piece of metal on a handle to scrape off the top millimeter. This was necessary because the board surface was in bad shape (sand, pieces of glass), and I didn't want to damage the planer.
After that I put it through the planer.
The round shape was cut using a router with a circle cutting jig and a straight router bit. I had to do .5cm depth at a time since that's what the router could handle.
The hole in the back for the clockwork was made with a straight router bit.
The individual hour markers were made using a rounded router bit. The darkening of the wood was a coincidence and a result of the router bit burning the wood a little. To find the exact spot for each marker, I first used a regular squares tool for the hours 12, 3, 6 and 9. I then cut a 60 degree angle piece of wood and drew the lines for the rest of the markers based on that and the existing lines.
After routing the hour markers, I then treated the wood with raw linseed oil.
The clockwork I inherited from my grandmother who used to make clocks out of old vinyl records. There was also a red second hand, but the color didn't fit with the wood, so I left it out.
Finally I bought and attached a keyhole hanger. I first drilled about .5cm into the back to allow space for the screw head when hanged and then attached it with two small screws.
