the steel backing plate handles all the heat rejection necessary, and the magnets stick to the steel very well. The superglue doesn't seem necessary, neither...
Hi All In addition to what Mike Johnson has written, if sand blasting is used and the resin is poured within 10 minutes, then very little oxidation takes ...

We sanded our rotor plates right before casting. We don't have sandblasting equipement available. For us it's about making do with what we have, for a solution...
Absolutely agree with you Steve. Same here. Thats exactly how we work and live too. And in an Indian remote village living and working with tribals, I probably...

That's the spirit Michael, Do the best you can with what you've got is what I say! Tim ... -- All the Best Tim from Tang It is never too late to have a happy...
I use a 4.5" hand grinder with a course metal cutting wheel to rough up the disks before casting them. It also seems to make the magnets stay in one place. ......
We use the superglue simply to hold the magnets in place until the resin sets, otherwise the magnets can move around in the still-wet resin like this: ...

Hello, I am interested in building a wind turbine, but would like to source the blades from somewhere. Has anybody used blades from Hydrogenappliances ...
I don't care for those blades. I woul suggest, for small/inexpensive blades that you contact Art Randolf. They're quite flexible (not as flexible as hydrogen...
Steve, That BadBoy Unit that you fellows built in NY (I presume). If you had no furling set-up and you experienced a bad storm with winds hitting 70MPH or...
I don't know, I haven't run the rpm up past 1000. If I lost the tail, I'd throw the brake switch, which shorts the coils and stops the rotor. The tail is...
... Actually, a 12 V battery won't charge at 12V. It needs about 14-15 V to charge and will "trickle" down to about 13.5V. I guess that the 12 Volt winding is...
I am in the process or designing a small wind gen for use on our caravan but have a problem. How is the power transfered from the gen? How do I overcome the...
We let the cable twist inside the tower pole. I have a connector at the bottom I can unhook, untwist, and reconnect. The turbine turns one way, then another,...
Jon, My low speed wind generator has a central disk with magnets attached on each side of the disk so their flux lines fold against one another and reinforce...
Dan, Fourteen feet diameter and each blade is 96 inches, 8 feet high, pointed in the middle, with a 24 inch deep cup. Three blades, 120 degrees apart. Tower is...
Michael, Yes. Currently you reserve a unit built to your specifications (20,30,40,50, or max 60 foot triangular tower built of 1 and 1/2 inch steel tubing)...
Available in 81.5 inch size and above. The one I like is 4 Meters or a little better than 13 feet for a tad under $500 delivered. They come in two models at...
Maybe I misunderstand but it seems to me like you're sweeping about 112 square feet (at best). (14' x 8') And you claim 12KW output. It must be in very high...
Steve, As usual your the boss but it seems a shame because the Alternator's do need to be powered. The Axial Flux movement seems to be headed towards lower and...
I don't need to warn him about anything. I don't have an opinion about the blades. I just asked you to stay more on topic. This is not a wind group, it's an...
Dan, You have to multiply by the height or chord of the rotors for the total swept area and a good handle on the torque moment. Regards, Lawrence ... you ... ...
Hello Dan, Have you thought about a double sided disk with magnets on both sides? My generator design uses a brass disk with 3 inch disk magnets mounted...
