This oak clock I made with wood from a tread from an old staircase, the same wood as I used for this cutting board

Materials:
- Wooden oak board
- Clockwork
- 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)

Tools:
- Router
- Straight router bit
- Round router bit
- Planer
- Drill
- Fine grained sandpaper
- Screwdriver

Process:
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.

I have been saying for a while that I need a clock for my workshop. Thanks for a quick, handsome how-to. I hope to get to this project next week.

Sounds good, I would love to see it when you finish.

nice job, sometimes simple is best. Its maybe worth mentioning that rags used to apply linseed oil can get hot and ignite when drying if left scrunched up. I leave mine laying out flat to dr. Strangle but true fact

That's a good point, I had a vague memory of hearing this somewhere, but stupidly ignored it. I have now properly disposed of the rags, and will include a note in the instructable. Thank you!
This came out really nice. Thanks for the share, I love upcycling materials.

Thank you, I try to only use wood that others threw out or gave away.
It adds an interesting constraint to what I can do with it since I don't choose the shape or form that it comes in.
In this case it was a 100cm by 20cm rectangular piece of wood, so no real constraints to speak of except that I wanted to find a use for the clockworks I just inherited.
I still have three more, and I'm looking for inspiration if anyone has ideas.
