To build the Trammel of Archimedes, follow these steps: 1. First, gather all necessary materials, including a drill press, a lathe, and various cutting tools. 2. Next, create the base plate using 1/4 inch steel plate, with dimensions of 6 inches by 8 inches. 3. Cut two pieces of 1-1/2 inch aluminum rod to fit inside the base plate, spaced evenly apart. 4. Attach a small bearing to each end of the rods, ensuring smooth rotation. 5. Construct the trammel body using 1 inch steel tubing, with dimensions of 6 inches by 12 inches. 6. Mount the trammel body to the base plate using screws and washers. 7. Install the bearings onto the trammel body, making sure they are securely fastened. 8. Attach a small pulley wheel to one end of each rod, allowing for smooth rotation. 9. Connect the pulleys to a pair of hand cranks, ensuring easy operation. 10. Add a small spring to each crank, providing tension and stability.
