aerosharp rewind

[stockers08]

hello good people
i hope you are all safe and well in these strange times.

i am looking for a little advice if i may.
i have read as many posts as i can regarding the ozinverter etc and rewinding the aerosharp transformer.
i have acquired a single unit. i cannot get my hands on a second to make a 6kw transformer,.

so i have decided i will go with a single.
can the original secondary (230v) be left in place and used as is. just rewind the secondary (now primary)

if so, what size primary would i need and how many turns for 24v?
i am guessing 14 turns and 50mm. (9:1 ration or there abouts.

i am hoping i can leave the 230v winding as is. 

i plan to use the wire from the 250v winding to make my primary  just unsure how many in hand i would need to make 50mm.

with a sufficiant sized board, could the transformer do short bursts of 4kw?


many thanks guys
stay safe

Hi stockers08,
Welcome to Fieldlines.
Of course obviously you are looking for Oztules.  He does check in, but not frequently.
To get you help more promptly, I know where you can post your question where Oz is more likely to see it.
There's an irony to this, but you'll have better luck reaching Oztules where he is more frequently seen:
Anotherpower.com
He regularly responds to inverter builds, whether help is need or not (and in those cases is full of encouragement).
Here's an example that may be relevant to you:

Oztules is not very well.

I see that you have posted on Anotherpower.com and 'Warpspeed' has replied.

'Warpspeed' is a retired power electrical engineer who specialised in the art of toroid's.

He is also a very nice guy, and really knows what he is talking about. 

He has also developed the Warpspeed Step inverter that uses 3 and a 4 differing size toroid's.

Very sorry to read about OZ  .
As i read about Warpspeed and the Torrids  , my brain went directly to StarTerk's warp bubble .

I'll jump over to Anotherpower and check out those posts too.

ClockmanFRA,

Would you be so kind as to pass on my concern and best wishes to Oztules, as I have only fond memories of our discussions "back in the day".
Things have changed since, and my attempts to reach out more directly are never successful.
