Decorative Vawt Mk2

thingiverse

A new and improved version of my previous vawt.. https://www.thingiverse.com/thing:5405518 Improved design, Increased speed and lower wind speed to start. Now spins so fast in moderate wind its a BLURR.. Super spiral glue to the base AFTER putting m5x16 bolt through from Inside area and securing it tightly with nut. (once tight a dab of super glue is recommended as once you glue on the spiral the bolt top is inaccessible.) Extra Parts Required.. 16.5mm x 1ft long aluminium pipe (I used a piece of transair pipe) 4x.. m5x12 set screws 1x.. m5x16 set screw 6x.. m5 nuts 4x.. m5 light washer 1x.. F688zz Flanged ball bearing (8mm ID. 16mm OD. 18mm Flange. 5mm thickness) 2x.. screws with rawlplug for mounting few mills of 99.9% isopropyl.. some petroleum based white spirit(!not the water based safe stuff!).. Before assembly thoroughly wash out the bearing with isopropyl making sure not to introduce any water or dirt (wear latex gloves or similar). once totally clean and spinning fast soak in white spirit to lubricate and protect the bearing from moisture or it will seize up after a few days outside. Ensure level mounting of the pole for optimal balance and spin. The post at the back of my garden is off slightly so I made the 1.6 Degree spacer. probably wont be any use to most but added just in case it is. UPDATE ON BEARING CLEANING METHOD. Take a pea sized amount of motor grease and mix it with 4-5 caps of the white spirits taking care not to introduce any dirt or dust into the mixture. If any heavier components of the grease settle out try not to get this on the bearing. Take the cleaned bearing and soak it in the mixture for a better greased and longer lasting result.
