Step 1: Preparation and planning
- A Kitchen cart (ideally solid wood)
- A bowl
- A router - this can be rented from most hardware stores, if you don't have one. You may also need a piece of wood to attach to your router to serve as the pivot point.
- Two bits for your router: one regular bit that's long enough to cut through the depth of your cutting surface, and a rabbeting bit the size of your bowl's lip.
- Some scrap wood at least half the size of your kitchen cart's top.
- 4 screws long enough to attach your cutting board to the scrap board.
- Measuring tape
The first step, clearly, is to get a kitchen cart. It's good to find one whose surface is not too thick, as a really thick cutting surface will require a larger routing bit, or more creative routing. The Forhoja cart's surface is solid wood that's about an inch and a quarter thick.
The next step should be to get a bowl (or bowls). It will be important in the next step to know the bowl's diameter as well as the width of its lip. I found two bowls that have the same width lip and the same diameter, but different depths, so I can change the bowl depending on the purpose or amount of food I'm cutting. It is also convenient to get a bowl with a flat lip, so that finely chopped food will not get hung up on the curve of the lip.
Finally, you want to think about the way you chop vegetables; this will determine into which side you want to embed the bowl. For instance, I tend to cut right to left, making it more comfortable to place the bowl on the right, so it's easy to sweep the produce into the bowl when I'm done chopping.
