Preparations for DIY Water Jet Cutter
Let’s lay the groundwork for a successful and safe exploration:
- Pressure Washer (Approx. $150): Obtain a low-cost pressure washer with a rating of around 2,000 psi at 1.7 gallons per minute. The suggested model is one of the most popular electric pressure washers available on Amazon, costing approximately $150.
- Modification Essentials: Familiarize yourself with the pressure washer’s internals by disassembling the plastic case and extracting the pump and motor assembly. Modify the system to eliminate the feature that stops the pump when the trigger is released. This involves disassembling a valve housing and adjusting its components for continuous operation.
- Additional Cooling Fan: Enhance the cooling system by adding an extra fan to the motor assembly. This precautionary measure helps to mitigate potential overheating issues during prolonged usage.
- Pressure Measurement Tools: Incorporate a pressure gauge into the system to monitor and regulate the water pressure effectively. Ensure that the pressure levels are within the safe operating range to prevent damage.
- Safety Measures: Implement safety precautions to handle the increased pressure, such as reinforcing seals and ensuring the pump casing is sturdy. Safety goggles and protective gear are imperative for personal protection.
- Electrical Adjustments: Modify the motor’s pressure cutouts to accommodate the increased power demand. Be mindful of the electrical circuit’s limitations and avoid drawing more amps than the system can handle.
- Abrasive Materials: Acquire abrasive materials, preferably 80 grit garnet, to facilitate the cutting process effectively. Ensure a steady supply for continuous experimentation.
- Cutting Head Assembly: Assemble the cutting head, comprising a tungsten carbide tube and a precision orifice, in the correct configuration. Utilize a ruby orifice with an 18,000-inch diameter to optimize cutting efficiency.
- Stainless Steel Piping: Utilize stainless steel piping for connecting high-pressure components, ensuring a reliable and robust setup. Follow recommended interconnect styles to maintain precision and efficiency.
- Abrasive Hopper: Construct a gravity-feed abrasive hopper, essentially a tub with a hole, to dispense abrasive materials to the cutting head. Consider anti-flow back mechanisms to prevent water from contaminating the abrasive.
- Protective Measures: Safeguard the system from potential leaks and water ingress. Adequate measures, such as placing the machine in a water-filled tub, can prevent unwanted consequences.
- Future Considerations: Contemplate future enhancements, such as adding CNC control for more precise and automated cutting capabilities. Explore low-cost CNC machines or consider innovative solutions like the “Waser” Kickstarter project.
