Todd,  Yep freight from OZ is aust post who are reasonable compared to the rest.  I am on "standard" freight from the US whatever that is.  Still have time to redesign the cushion drive which is already done, now to get it made ---Sigh>

Did you not say you have an electric water pump??  If so a few details please??  I have just taken Paul lamars figures and thought no more about it -- until last night.  200 litres a minutes (quoted) is way over kill.  THe water would not have time to collect any heat.  THat is nearly 1 gallon US per second!!  Why?  THe electric voulme is??  I would have thought that one foot/ second, water speed is more realistic.  Am I mad as usual?

Neil, I feel your pain. As a Canadian I too am subject to the rise and fall of the dollar and have learned to play the shipping game.
I am surprised about the shipping time to Oz though as I have bought a few items from down under and shipping was fast.
  My radio is an X-com which came from there and last winter I sent it back for an update. It was there and back inside of 2 weeks including shop time. I also have a Davies Craig EWP and last year I wanted to upgrade the electronic speed controller to their new one so I actually got it on Australian Ebay new including another pump as a spare at a great price and it was here in a week.
  Ebay.com now has a global shipping program that simplifies exports for the seller and saves the buyer all the brokerage fees, but it's slow and usually takes about 2 weeks for shipments out of the US.
  Amazon.ca Prime, on the other hand has it figured out. I see that there is an Amazon.au but it seems that inventory selection is lacking. But have heart because if it is like the Canadian site, then you'll find that they will increase the selection exponentially soon.
  All part of Jeff Bezos plan for world domination, before Google does it, or Apple, or Elon Musk......

Hi Neil;
   I can't confirm for certain but yes, 2.77" sounds about right.
  After the flywheel and damper drive modifications to increase clearance, I still only had 1.43" to squeeze it in there, so that is why I also shaved a little off of both sides of the rotor cup and also machined a shallow depression into the backside of the psru backplate to allow mounting the stator close to the plate and still have clearance for the windings.
This link will show a pic of where I measured the 1.43"
  At a little over 1.5" before any modifications to increase that room, then you are much better off than I was when i began. 
   When I decided to try it, I really had no more than the desire & determination to experiment and a "Hairy chested hero" idea that I set down $400 at the local Harley shop as a bet that I could make this work, knowing also that I was modifying an expensive PSRU, that is no longer available for purchase. That gamble paid off for me and I proved that it can be done.
  So I would say that you gotta ask yourself whether this is something that you really want in your own installation and if yes then put that money down on a single rotor/stator and go to work to see if you can make it work for yourself on your own design.
  Then if you are as happy with it as I am with mine, you can figure out at what cost you can offer it as an option.
  If I were in your shoes I don't think that I would go to the trouble if your only motivation is to provide it as an option for others. But if like I said, you want this for yourself as well, then go for it and if successful and affordable, then others can have the option of one as well.

Todd,

                   From what I can gather  the ID of the stator is 2.77
inches.  Does that sound correct?    To land a unit from the US or buy
in OZ , the cost is  Pushing $375 AUD or $285 USD.  I have a little over
1.5 inches to mount in between the drive and the plate. Do you remember
what space you had?  Thanks,  Neil.
