The goals of this project are two-fold:
- Make an awesome and beautiful citrus juicer
- Create a mechanical/metal project that someone can build with almost no tooling of their own, as a means of learning more about outsourcing manufacturing steps.
The result is this juicer constructed of waterjet-cut mild steel plate, using wedged mortise and tenon joints, as well as some commercially available hardware. This is not a cheap project by any means, but produces an absolutely beautiful piece that works well.
What you'll need:
- Tools as shown in the image above
- Hardware as shown in the image above or similar (Parts list shown below as well).
- Most of the hardware can be substituted if something is easier to get (for example, you don't need brass acorn nuts; any nuts will do fine; I just like brass)
- The DXF for this pattern will only work with the juicer parts shown. If you get different parts you will have to alter the DXF.
- Use the attached DXF and get your parts cut at a shop of your choice
- See my tutorial on getting parts cut for help with this.
- Parts must be 3/16" unless you alter the pattern to work with a different thickness.
--NB: I'm including Mcmaster #s for all hardware, but many of them are sold in packs of 25 any you only need 1 or 2; check your local store first unless you are a hardware horder like me :)
