GWatPE said Hi Bob,

I think I put Jim onto the WattsUp meter. I got mine years ago, online from the manufacturer in the US. Around $50- . Probably more, better spec units available now.

These are used by modellers testing electric motors in cars, planes etc.

Gordon.

I did a google search on that meter a while ago. Apparently its no longer available. If anybody finds a suitable substitute I would be interested too.

TINKER,
From the info in the posts above This model WU 100-B seems to be close to what I'm reading, If not, there are a few more to chose from.

Hi Greenbelt and Jimbo

I found the site it has no specs on the 100-b but it looks good.

Thanks a lot

All the best

Thanks Greenbelt

It looks like a handy tool to plug in and check things with better than a heap of multimeter s wires and sparks smoke and the exiting actions.

All the best

Sorry for the slow reply
top work Jimbo!

looks to me like 1/2 the axial flux mill is already there, just glue on some magnets to that hub, start winding coils, another "hub" for the other side and some more magnets and you're away....

Luck favours the well prepared

Wish the AX/FX was that easy.

Getting warm here now, summer is on it's way, time to go back to work and make some $$$$

The AX/FX will have to wait for awhile or until Gordon or Phill decide to give away some of there drawings and or specs?

Thanks for your response.

I'm building an ax-fx from scratch. Just follow my lead and let me make all the mistakes.

I've started a thread in Windmills called "New Ax-Fx Design" and it started out as a reply to John Tulloch (Oxtules) showing him a little sketch I'd made. I wanted to throw it into a PM reply, but the system wouldn't allow any pictures, so . . .

Right now, I'm working on manufacturing my own lightweight blades from coroflute plastic (it's like plastic cardboard more or less). Everyone has told me they'll explode; they're probably right, but I'm building them anyway. I just like building stuff from scratch and if it works or not is part of the fun for me.

So, like I said, hide and watch; learn by my mistakes and before you know it, you'll have your own "working" ax-fx flying above your home.

Hello Mac

Yes I have been following your AX/FX posting.
Sure' go ahead and make the blades the way you like if they don't work then make ones that will work. If the alternator works then I am sure you will come up with some blades that work as well. You may want to reinforce the lower or root section of the blades just to be on the safe side.
Mistakes hummmmmm you can show me what not to do.

Best of luck.

Jim
