Hello all, I am building a 1kw axial flux turbine and want to know: is a furling tail a necessity? I purchased the 10' diameter, 3 blade fiberglass blades...
A straight tail will keep the blades in the wind. A furling tail will move the blades out of the wind when the unit overspeeds, preventing coils from from...
And even furled, the mill will still spin - just at more sane speeds. I'd not recommend going without furling capability..... Be well, Mike -- Zone 8, Texas ...
A furling tail protects at least three things; your tower, your turbine and your blades. Sounds like your blades might be covered. You might want to sacrifice...
Okay, how about the tower then. This may be a bad idea, but I was considering using television antennae towers, with guide wires. I am not sure where to get,...
A lattice tower with (or without) guy wires is possible, but needs to be engineered for the size of the wind turbine and the maximum wind speeds your location...
How do I make a furling tail where the alternator is mounted in the center of the pipe? Most all of the instructions I have found have had the generator and...
The tail is offset and angled, and gravity makes it work. Due to some comments about our tail, we tried a design modification, and added a "T" to the tower...
Look closer at the http://www.otherpower.com layout. The alternator is off-set and not on the center. Gravity on the tail keeps the mill oriented properly...
Our design however does keep the alt centered and not off-set. we tried offsetting due to some advice we received, and found little difference. The off set...
These are a bit smaller than the ones we normally use, but will still generate at least 500 watts. Check them out at http://www.green-trust.org/products/ We...
How much are the bigger ones? Mark ________________________________ From: axialflux@yahoogroups.com [mailto:axialflux@yahoogroups.com] On Behalf Of Steve...
Are these the ones w holes for screws? Mark ________________________________ From: axialflux@yahoogroups.com [mailto:axialflux@yahoogroups.com] On Behalf Of...
how many more do you need for the minimum to get the ones with the hole ... From: Mark McElvy <mmcelvy@...> Subject: RE: [axialflux] $36 for set of 24...
The N50's with 2 double countersunk screw holes are $17 each, plus shipping. A deposit of 50% will allow me to get the manufacturing order in. These are custom...

It's a bigger, more powerful magnet. And yes, it's expensive to get the holes manufactured into the magnet. You can't "drill" a hole in the magnet. Having...
We reached our minimum order. If you want a set of these, please get your order in now. It may be a while before we can place another order. -- Steve Spence ...
OK, makes more sense now with that informaton. I don't understand why a drilling process wouldn't work though. Best, wes On Sun, 07 Dec 2008 17:18:57 -0500,...
If you could get a drill bit through the material, I'm pretty sure you'd find it brittle and prone to breakage, as well as affecting the strength of the...
I may. I can't get past that they're over twice the price with holes...even if they are a little bigger. Best, wes On Sun, 07 Dec 2008 18:14:12 -0500, Steve...
