Cut the can top off below the chime; deburr. 2. Print cap, stands, hub, syringe cradle (and diaphragm rings if using a balloon). 3. Cut the foam displacer with the template; 2 mm wire rod through it, into the 3 mm brass-tube guide in the cap. 4. Cap on the can (grub screws + silicone); syringe in its cradle; 4 mm tube between. 5. Skewer crankshaft in 623s on the stands; crank discs 90° apart; wire con-rods. 6. CD on the hub; balance with a coin; tea light under the can.
