Drill water pump

This is a drill water pump. You can use 4x120mm nails for creating the shaft of this pump. For example, I used a nail. Assembly Steps: 1. Cut off the top of the nail. 2. Cut a 10mm piece from another nail and weld it to the main nail section to form the shaft key. 3. Insert the shaft into the impeller hole and secure it with the impeller lock. 4. Add grease to the friction areas within the pump caps (I used bearings grease from my washing machine). 5. Assemble the pump, using grease or sealant to seal the case-cap connections. 6. Secure the caps to the pump case with small screws.
