Hi guys. Great work and great project. I watched a documentary about blade designs and they had one based on a sperm whale fin. They got intrigued by the propulsion power of such a big whale with such small fins. The key is where the is like a joint in the fin, the bulge creates a vortex and speeds up through water and the same design applied to a wind mill proved to be of superior efficiency. text me if you want more info and I'll try and find it again. I could draw it for you.

ataching some 1/4 plywood will give you more performence

Another reason to not glue the the two blades together is the expansion and contraction of the wood.  Excellent videos!!

Hey there, Dan -

Love the videos. You've got some cool stuff going on there. I was wondering why, since you've got a table saw, why didn't you half - lap these two blades? Once you had them squared up, youi could have marked them and cut 1/2 way through the thickness of each board and assembled them that way...just a recommendation. Love the idea -

Keep up the good work, and be safe!

:-) Great Idea, actually check out part 6 that I just uploaded. Great minds think alike, I did this video last year.

So I see. I didn't know there was another video in the series. Great work!

Thanks for showing this. I've always wondered how to make the blades. Is there any advantage to having the blades come to a point?

[stimulater7]

yep all looks good .... whats the advantage of say a three blade desighn ?/

3 blades have less yaw or rocking and are said to be more balanced. look at the wiki page for turbines

[n2gpin]

There is also more surface area for the wind to push against, increasing the force transferred to rotation.

This is a great series of videos for the experimenter. Thanks for producing these and keep up the Awesome work !

I heard that the Netherlands have these things called windmills; oh yeah for like more than five hundred years now...

[kantwinnada]

hey Dan, Love your videos and am happy to see that your not catching anything on fire! LOL Was wondering if you are going to show us how to actually "hook it up" so we can get electric?

I've spent the last hour or so looking at HAWT & VAWT no one is telling me how to actually use it. Have a great day and again thanks for your videos!!!

This is all good stuff to know

[sockpuppetsfromhell]

I would cut a 1/4in notch out of each blade (maybe with a router and chisel) where it can lock on to the other like Lincoln logs. That set would be just fine though, deck screws can work miracles.

That is in the next video part, It is the advanced hub design. This was just for rookies:-) Actually I used a table saw.

Thank you for the comment.

You make it look easy. Is the DO it Yourself Turbine Link Your Video too?
