CD Windmill

This is a metal working project- brass and Stainless and  also nylon and plastic CD's
This is a decorative wind mill made with CD's to catch the wind. They have prismatic grooves in them to refract the light and give off a variety of colors. There are 2 CD's mounted back to back on plastic blocks that are then screwed to the aluminum rod with  8-32 screws.  The rods are fastened to the hub with a 3/32" SS roll pins. All the fasteners are stainless.
This one has 7 arms on each side and they are counter rotating. Each CD is turned at 35 degrees- one wheel to the right and the other to the left. They have high quality sealed bearings on the wheels and the center block and each one has a cap screwed on top to keep out the water,

This one will be a gift to my daughter.

Cheers, Jim

One way to use outdated materials. Must put on a nice light show when the sun hits it just right. Nice work as usual Jim.
That really creative, very nice job.  I'm sure your daughter will love it.

COOL JIM !!!!

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.

A piece of art for sure, and it looks really cool. Reminds me of some of the spinners I have seen in the past and in the movie Twister. Well done.

Modern art!

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".

That's way cool! I have a stack of unburned CDs than can give their all for one of these.

JJ that is bloody cool... however if that was on my neighbours porch, at the wrong sunlight and a bad choice of music, I'd write/complain to my council... unless it played XXX DVD's.  

If your first cut is too short... Take the second cut from the longer end... LBD

It's all about recycling

Pretty ingenious use of the CDs, and their highly reflective surface must look nice on a sunny & windy day.
Very Nifty project. good use of old out dated CD's and a tribute to a time we enjoyed playing the CD's. You described a well designed and executed build, looks great. Super Job Jim.

Thanks you all for all the nice comments.

Hi Dark lightning. The hardest part of the project was making all those little 3/4" square blocks with the round section turned on them to accept the hole in the CD's.

Hi Alex, it does throw quite a lot of reflections when it gets going, My other one, with 9 arms on each side, lights up my shop at a certain time of the day!!

I like it,   might have to buy a new lathe after all.  Do the CDs stand up to the outdoor exposure?   Sunlight can be a problem with some plastics.

Thanks Albert I have another one with 2 rings of 9 arms ( 36 CD's in all) and it runs all year. The CD's get dull after about 3 years  in 3 seasons. I usually take it in  in the winter when we are gone. Last year the other one was frozen in the pipe that is always there in the ground so it stayed out all winter. The wind and snow was so bad in the winter that it flexed the rods and the CD's hit the pole and chipped every one of them- it still ran fine.. So I changed all of the CD's and made new spacer pins for the reels that put them out 3/4" more on a side for more clearance. I will take it down earlier this year.

Another great visual yard art display!

I've been collecting the glass platters from computer hard discs I disassemble for the magnets. Never could think of a good use until now 😀

3-3/4" highly reflective and seem impervious to the elements. Dead-flat surface so just like a mirror (no prismatic effects) but the drives have the hubs and bearings (aluminum) so mounting would be easy. 
Hi Bruce. I Wait to see you windmill. With a  CNC you'll be able to make the needed parts a lot faster than I could!!

Microwave ovens each have two nice sized magnets in them too. I take them apart at the scrap metal drive and I collected a dozen in May!

Jim, are those RE magnets or the alnico magnets (black) like found in speakers?
Hi Bruce, I think they are  alnico magnets- they look just like the ones in speakers. I must have 30 of them stuck to the  door in my barn waiting for them to tell me what they want to be!! I did put handles on a  few and use them to hold up stuff on cabinets in my shop. They are pretty huge for refrigerator magnets, though.

I've been salvaging any kind of magnet I could find since I was a kid, just something about their magic 🙂

Get enough on your door and you may become the new magnetic north that all the birds and lost cub scouts will navigate to!

Put a few into a cube of wood and they make great stops for alignment on the drill press!
