Windmill mk4

Okay, so I've uploaded something like this before. However each time I've had to replace the windmill due to ageing of the ABS plastic I use I tend to make a slight change.

This is the model that I've put up this summer.

Compared with the previous version (https://www.thingiverse.com/thing:451363) it's mounting is more flexible both how you can mount it, how much variation is possible with vertical placement of the windmill and also because it can flex a bit more then the previous plastic stand.

For this version one needs to buy:

• M8 theaded rod, stainless for endless reusability, zinc plated might start to corrode in a while.
• one M8 nut
• one M8 bolt hex head, If I recall correctly about 80 or 100 mm long.
• One M8 round coupler nut (I used 2 because my bolt was slightly to long)
• One cleaned out 608 bearing.
• 4 sunken head Screws

I clean out the grease from the bearing and remove the dustcaps from the bearing. As long as it moves it won't rust out to much. Cleaning it will give a windmill that will turn at the slightest breeze

Tools:

• M8 thread cutting tap
• Blowtorch (or your kitchen stove)
• Some sandpaper or file

Assembly:

Try to test fit the arms to the hub and sand of file down till they fit snuggle, then either use acetone (if printed with ABS) or glue that works with your material. Remember to put the cups all in the same direction ;)

Insert the bearing into the hub.

Apply heat to the hex head of the bolt and when hot enough press it through the hoed (hat). This will make the hoed watertight.

Put the bolt thought the bearing in the hub and screw on a coupler nut to secure the bearing. Do not overtighten, slightly loose works best. If you've got the perfect length of bolt then you've got some nut left to use on the threaded rod. ( I didn't and used a second coupler nut)

Use the tap on the M8 paalhouder (poleholder) to make some threads.

Put the nut on the threaded rod and screw the threaded nut rod into the paalhouder. And tighten the nut slightly against the paalhouder.

Put the threaded rod in the coupler nut of the top part.

Screw the paalhouder to a wall or fence post.

One could also extend the threaded rod and/or spike it into a something like a lawn or garden.

Have fun.
