Carving Wooden Wind Turbine Blades. I carved these blades from laminated red cedar last year (03/20/17) for the 1 kW axial flux wind turbine. Some of you have probably seen the original video already. However, due to copyright issues, I've had to re-edit and upload it again - sorry for the repeat.

These aren't just blades, these are works of Art. Well done sir.
While having an awareness of certain wood forming techniques presented, I did not know they could be done to this extent. Thank you, James, for an excellent and innovative approach. Well done!
Been following your videos, you truly are a great craftsman. Lots of love from Nigeria
It is nice to see genuine green reusable energy.
A 3d printer hands , perfect blades .
Have you thought about covering the blades in fiberglass ? To keep them out of the weather. And making sure them stronger well maybe stronger.
Gran trabajo
Nice!
Spruce might be a better wood to use - it's a bit heavier, but harder and stronger than cedar by a wide margin. Cheaper too, at least here, and it's fairly easy to find straight grained pieces that are relatively free of knots.
Thanks for the tip, John!
I would not have expected any less from the master himself ! I am eager to see what you come up with your reaper turbine project
John from I build it sent me, glad you did I can feel a binge watch session coming on.
Un gran trabajo. Felicitaciones!!!!
Great to see any video from you! And thanks for sharing good design. The plans are clear and precise.
Wonderful craftsmanship.
adorable, man, you have golden hands,👏👏👏
Parece magia cuando se le ve a usted trabajando con esa precisión la madera, muy buen trabajo.
Un gran saludo desde Albacete España.
Nice work
Awesome woodworking
I like the idea for wood parts for the turbine. Sure, they aren't as durable as steel. But, they're easy to fabricate and light! Looking forward to more on the Reaper too!
Some small aircraft manufacturers still use cedar as their choice material for prop's. If it's good enough for a small plane, it's good enough for a small turbine imo. And it's renewable!
@@JamesBiggar LOL, that's funny I really didn't expect it, I thought only the old planes like wright brothers use them. Could you give an example of such a plane right now?
Good job. Pretty good...
Excellent work 👍🇲🇽
Beautiful work!!
Amazing work. Id finish 1 and be pissed I had to do 2 more.
Lol, that's how I felt the first time. But you get used to it, like anything. I have something better planned for carving the blades for the Reaper turbine though.

Good blades.
Молодец как всегда супер лайк👍👍👍👍👍
Муслим Юсупов он не понимает😀
Nice 😀👍
What about aluminium/metal blades? What's your opinion/experience on the subject?
James, I always enjoy your craftsmanship. Do you think they would've been stronger, if the lamination was all ... clear wood? I look forward to the Reaper blades.
Thanks! Yes and no - it depends. Perfectly clear lumber is nice, but rare these days and expensive when it is accessible. Generally, if the knots are solid then there's no structural compromise (at least, that's what the NRCC teaches us in the carpenter apprenticeship). If the knot is cracked, loose, etc, then it's no different than a hole and becomes a problem. I then knock out the knot and fill the hole with resin (when it comes to turbine blades). The broken blade actually didn't result from anything wrong with the wood - but it was my fault regardless. I broke that blade during the initial turbine installation (turbine swung around on the tower as it was being raised and the blade hit the deck). I wasn't in the mood to carve a new blade after that, so decided to do a quick temporary fix by cutting out the damaged portion and gluing in a new piece. I didn't expect it to last, but it held up for 2 or 3 months before the piece started to de-laminate. I saw it the night before and figured I would lose it by morning. Sure enough. Once it de-laminated then the blade became too flexible in strong gusts, bent back and hit the tower.
Thanks for the back story on how the blade broke. It all makes sense now. I had saw you epoxying a Knot in the vid and had thought that would hold up. When I used to make pine furniture I never worried about live knots, but always knocked out dead knots and glued them back in. James you ROCK!
@Rosen, @James Have you thought of using flat metal in the middle and then sandwiching wood pieces to the base metal with screws and glue? That would add to the strength and even lower your cost if a full length wood is not available.
Great work , how can i get the detailed measurments in order to make one of those effective blades? Thank you , all the best.
good job
Nice....
Are you going to do this with fiberglass and foam in the future
Very nice! Have you ever thought about fiber glassing those?
Thanks! Yep, but my fiberglass skills aren't quite up to the task just yet lol
mi jenerador es de24vcuanto me cobraria por aserme 3 blades
mayb u r due for a 3D printer or cutter :-) enjoy ur video thank u
Thanks! A cnc mill is a bit too expensive for my budget atm, but will be building the next best thing for the Reaper turbine blades very soon ;)
Why did you choose cedar?
Light weight, naturally rot resistant, easy to work with (compared to composites). Some small aircraft manufacturers still use cedar for their propellers, so it has a pretty good reputation for these applications.
Great job but, far too much work.
Thanks! But 6-8 hrs of honest work to save over $300 for reasonable quality blades of the same size is a pretty good deal imo. Won't be any cheap plastic composite lawn ornament blade sets or hacked up pvc pipe attached to my turbines. Just finished up some molds for fiberglass blades for the new 12 ft dual pmg turbine. Video on the blade construction will be uploaded next week. So now there won't be any more wooden blades attached to my turbines either ;)
A wood CNC milling would lower that hardship. There's plenty of bad ass DIY CNC in youtube, and they're not complex, arduino shit, etc
Maybe it is too much work for you. Other folks might just enjoy the challenge.
This isn't hardship, it is a labour of love. Where is the green energy in an electric cnc cutter.
if you have no time for audio , don't make a vid
What language do you suggest or would you like him to make it in all of them.
