Very nice work! I wound 1000s of stators for my company but this is truly a work of art. Where can I get parts and is there a site that shows how to wind these?

Thanks

parts are all available locally in manila, the irons used costs P110 per kilo, this traffo used about 9.5kgs. so total cost of irons is P1045 or U$24...

stateside, you can get then from Thomas and Skinner.........Thomas and Skinner
