For this project the only material you'll need is a hard wood dowel
an inch in diameter. I used a hard wood for the original device, but (without thinking/realizing) used a soft wood dowel for the device documented in the Instructable.
I used the following tools. As always if you don't have them you can acheive the same effect a different way with what you have...or use it as an excuse to buy a new tool.
* Tape measure
* Bench vise
* Work piece protectors
* Straight cut router bit (I used a 1/4" bit. This will vary depending on the thickness of your key.)
* Drill with 1/4" bit
* Wood burner with tips (Optional)
