10 Blade dual windmill

Dual 10-blade windmill Requires: 3 x 608zz bearings super glue (optional but helps) An 8mm dowel or bamboo cane Assembly is a case of pressing the bearing into the recesses on the rotors and the ‘base’. They're intentionally snug but do fit with a little force. The spigot/rod can be glued into the hub and the rotors go onto the shaft in any order with the spacer between. The nut should snug up without pressure on the front rotor bearing but just enough so they don't wobble. The spigot is then pressed into the centre of the bearing that was pressed into the base.
