I built a small strong vane powered alternator to replace the old generator on my 1941 J4 Cub. That was how they recharged the battery on the limited electrical system back then. I used a Delco alternator and adjusted the pitch so it didn't scare me from the high speed screaming. It came apart in flight one day causing fear and grief. I researched the alternator market for one with higher capacity thrust bearing and found a nippondenso. It worked great. For all you sharp shooters out there, no it wasn't stc FAA approved. I have had my life nearly ended several times by shoddy A&P mechanics. Being an ex Air Force mechanic, it's my life and I'll do the maintenance thank you.
So good to see people discussing and finding better ways to do same thing. Is there anyone who has professionally worked on small wind turbines projects ? I would like to discuss a couple of things and would appreciate any assistance.
A variation on the Hub to make it stronger with a bit more bite in the overall pitch to allow efficient use to my most common wind preference is an easy carry forward. You have provided me with inspiration! Thanks.

Thanks for the idea. I intend to build a slow speed fan in my workshop to circulate warm air from above the stove and across the roof, down to where I am. It has to be big, but slow moving, otherwise the wind-chill outweighs the heat gain (as I have found out with a desktop fan). At the moment it takes about 2-3 hours to warm it up by natural warm-air currents so hopefully this would speed that up.
@@devfern2270 I found out at more or less the same time about some very small fans only about 6" diameter. Spacing them one at each corner and each of them blowing horizontally towards the next one, creates a gentle draft and gave me the effect I wanted. They are often used by bootleg cannabis growers in confined spacers.
@@devfern2270 Difficult to advise you without physically being at your place to see the problem, and even then I am no expert. Can I suggest you discuss the matter with your local garden centre who will give you expert advice.
The 90 degree cut at the blade base will like be the point of failure, better to just cut those two connecting points at 45 degrees and have the extra material for strength.
Great insight into the build just subscribed and it’s a nice compact turbine I also have built a homemade 650 watts wind turbine, a treadmill motor turbine and a little but powerful ametek 30v turbine and built 2 diy solar panels, be careful in high winds one of my first turbines blew up 😕and now have only 2 wonderful turbines working daily 😊it’s very satisfying watching those things working, keep up the good work buddy 👍
Teach me too. If i want air to be pushed fwd & sucked from back like an exhaust fan. shud the blade curvature be different. Why do some house fans have 4 blades? Is it better for windmills with low wind speeds to have fewer blades?
You've got a grinder and a welder and you still work on the floor? Build a workbench then build a vice. Nice little project though looking at the generator, I think you should upscale to something that will spin a car alternator.
As per my previous experiences u should add three more blades and also increase the length of blades for better results n more stable rotation even in slow wind speeds
Interesting video. I heard also about so called "vertical turbines" - I am not sure if I wrote the name in English correctly. You could make a video showing how to construct such a turbine. Regarding to this video maybe I am wrong but I am a bit afraid if this construction resist in case of very strong wind (eg. screws, pcv, welds).
A creative idea... you said Wearing eyeglasses when welding but it hasn't angle grinders power tool protection! It can cause damage if stones are exploded.
NEW Physicist 🌹👍❤️ good afternoon my friend very nice very good your working and your video I like this work goodbye I’m OTH Riyadh Saudi Arabia 5-2-2018 7:20 PM
I have been building wind turbines for over 50 years. Using PVC can be really dangerous and Highwinds, just for your information. Not being negative, but you can build a much more robust airfoil using carbon fiber rod and dollar store foam board.
I find that cutting the square notch at the end will eventually cause it to snap at that point (even with the steel), better to just a 45 degree angle there and have the extra material as reinforcement.
Waouh is great. I like your videos . your are amazing. I'm a Cameroonian student and a fascinating to wind turbine. I want to learn to make it how can I do? Please can you help me!?
hey try conveyor motor on the turbine stator for your wind turbine instead and plug in wall (you get more out of it.)plus you get five billion views in five years. it has sixty magnets right conveyor is always one rotation per second on you put on dial. do it fast. then upgrade magnets for more amps and voltage. use power box extra one electric company one extra (IT WORKS YOU JUST HAVE TO REMEMBER TO GREASE IT.)
Cool solution. But the rear edge of the blades is allways 0° this is ideal. I guess it is worth to spend a little more time and fasten the whole blade with an angle. In this case you should put the edge with the different angele to the rear. I would expect that this would fit better to the different angle of attack along the different sections of the turbine. Do you have some experience what wind speeds can be hanled by such a construction?
The supported edge should be the leading edge. Twist them. Also as noted in some of the other coments PVC might not be best choise as will become brittle or melt in the sun.
This is a nice design. There's something I've never understood however. Why are wind turbine propeller blades so narrow? Wouldn't more energy be transferred to the blades if they were wider?

This is a great great idea. Don't listen to the negative comments from people who criticize others, but do nothing themselves. Keep up the good work!
+Robert Baker, Thank you for your support.👍
That will totally work. And adjustments could always be made to improve it, if needed. All by hand, great job and thank you.
So good to see people discussing and finding better ways to do same thing. Is there anyone who has professionally worked on small wind turbines projects ? I would like to discuss a couple of things and would appreciate any assistance.
Good job! Keep them coming. Thanks for posting this.
the bike bearing and chains is a great idea as it takes away the strain on the motor's bearings.
Fantastic, Sir! Twisted, slim blades for a minimal cost! That's clever. I wish you god winds! Best regards, Andreas, Sweden
your all videos are awesome
Very easy to make. You my friend, are a genius.
I knew he is going to get a lot of pain for welding even before I read the comments. :-) Anyway, thanks for sharing. Good job!
+Vilo Conshmillo 😂😁thanks
this guy has not got the faintest idea of real life in the physical world of engineering
A variation on the Hub to make it stronger with a bit more bite in the overall pitch to allow efficient use to my most common wind preference is an easy carry forward.
You have provided me with inspiration!
Thanks.
Great way to show a general concept.
Thanks for the tip! Realy appreciate it!
Welding level 1000, very smart little brown ! :D
Yes, this is great idea. I was think more the along the idea of soldered aluminum, but that might be bitting off more then I could chew.
start small and work your way up to bigger and better things good job use what you can find
Brilliant. The simplest plans are usually the best.

Super. Very helpful. Keep posting bro
excellent your explanation.

Thanks. Change the chain for a belt
Thanks for making this video. Awesome.
Good technology and very very good a
Excellent.
Very cool!
Pls post a follow up as sool as you get some wind so we van see it do ots thing!👍
great video ...cheers
As per my previous experiences u should add three more blades and also increase the length of blades for better results n more stable rotation even in slow wind speeds
If there r more blades wud it really be better in low wind. Plz help.

Instead of welding one can drill holes and use bolts to secure the pieces at 4:30...
Good job thanks

My brother, I asked if it was made of aluminum with a thick thickness. But it looks like that can it be mounted on a zenithch750 stol plane?
very nice
A simple idea you can go to a local electronic repair shop and take a ceiling fan use the blades to make your own wind turbine
This is going to solve all the electric problems in India.
Bhai nice

Blades are kinda thin. Looks good
to keep the pitch constant the wdith of the blade is not linear but arctangent of the distance from the center .
10/10 for effort
I had this idea for a long time now
it look good when finished thank
This is a nice design. There's something I've never understood however. Why are wind turbine propeller blades so narrow? Wouldn't more energy be transferred to the blades if they were wider?
I think more heavier it gets if blades are big so diff to turn if low wind
A grinder and paint makes a welder what he ain't.
They'd work best if their 'pitch'-angle was reduced from the hub to the blade tips; like the huge commercial
commercial wind-turbines.
I also work on this topic which is quite interesting
0:34 "Safety First" but he has removed the grinder safety guard...... LOL
