Turnabout - A K'nex windmill

Ahoy!

Many a time now I have tried to come up with a design for a little windmill, and this is my latest and most successful attempt. It's a small, simple and stable design that catches the air very well. The best feature of this windmill is the rotating head, which allows the tail to rotate the blades straight into the wind, regardless of direction.  It preforms very well in light wind yet can handle very rough and gusty weather. I've left it out for days on end without having it malfunction.

Enjoy!

I really want to build this, and I have all the pieces except I only have two (2) square-9 hole panels. Help?

[the_burrito_master]

wrap the frame in plastic wrap duct tape,packaging tape, a it'll work even better ;)

[I_am_Canadian]

Sure, just make as dense a panel as you can with snowflake and yellow connectors, green and white rods. It probably wont be quite as efficient, but hey, its K'nex :-)

[Knexman15]

Ok, I wasn't sure if it would still spin because of more gaps in the tail and the blades, but I guess it will work. Thanks!

[I_am_Canadian]

Im sure it will work, it probably just wont spin as fast.

[Zeethesquirrel]

Can you make it so the video is only viewable from instructibles not youtube???

[I_am_Canadian]

Why would I do that?

[the_burrito_master]

Ha i knew this was from you just by looking at the first picture. Wonderful job.

[I_am_Canadian]

:-D

Thanks!

[knex builder36472418]

hey mate, this looks sweeeeeeet, i might build this

[MegaMetal8]

Very Nice, keep it up.

[I_am_Canadian]

Thank you!

[MegaMetal8]

Tis Ok

[Zeethesquirrel]

I have a question I_am_Canadian next ball machine can u make it not using the orange 5-ways with tabs? because I only have 20 of those and I can't build any of your ball machines (but maby the circle one

[I_am_Canadian]

Hey :-)

I'm not building another turnpike-style ball machine, but most of my ball machines use those pieces regardless.

Stay tuned :-)

[Zeethesquirrel]

Cool I only have 26 of the orange tabbed but I have a butload of peices and just something else I built your circle ball machiene and I have big ideas I'm building a ball machiene on top of it :D if I make a vid I'll give u a link

[I_am_Canadian]

Sounds great!

[MegaMetal8]

Im Not IAC. You replyed to me. =)

[Zeethesquirrel]

anyways he still got the message so it doesn't matter

[MegaMetal8]

kk

[Zeethesquirrel]

I did ???

[MegaMetal8]

Yes.

[~Vortex~]

VERY VERY COOL!

[I_am_Canadian]

Thanks very much!

[DJ Radio]

Cool stuff bro. What exactly is the purpose of the wheels though?

[I_am_Canadian]

Thanks!

It allows the head to rotate on the base, so that it can take wind from all sides.

[DJ Radio]

Couldn't that happen without the wheels though?

[TheFoofinator]

Ball Bearings, works in the same way.

[I_am_Canadian]

You could, but depending on your design you'd either have enormous amounts of friction or just an extremely unstable connection.

I don't know where anyone gets any of those square panels. I personally don't have any and have never seen one before. But anyways, that's a great windmill you have there :D

[I_am_Canadian]

Thank you :-D

I'm working on a substitute, as apparently those panels arn't too common. I think one came with Trampoline Tower, thats where I got mine at least.

[Seleziona]

Ohh, okay. I never really got any big knex sets like that. I usually got my knex from garage sales, and you get what you get from them. lol

[I_am_Canadian]

Too true :-p

[TheRacker]

I have tons of them from my 6ft ball machine, a really old knexcavators set, and some from other places too.

[I_am_Canadian]

Score! I'm glad I'm not the only one :-)

[Shadowman39]

This is great! You have a lot of panels. For the record, it would be cool to build 100 and line them all up like a wind farm. :-P

[I_am_Canadian]

Thanks! Yes it does use a lot of panels... Perhaps a bit of a drawback.

The K'nex windfarm would be a pretty awesome sight :-)

[instruct39]

very cool, great job!

[I_am_Canadian]

Thanks!

[Gortess]

Good stuff as usual. Good job with the video editing :-)
