Yes, that's starting to look like a good idea. I'll do that. I have two of each type of 3kW cores so I'll measure one of each and compare them.   Quote   That may be excellent top quality steel you have there, but some Chinese guy has probably bought a lot of odd offcuts fairly cheaply as scrap, which all ends up looking a lot worse than it actually is. So you may be in luck. But its probably worth knowing what you have before putting a LOT of time and effort into doing the winding. Haha  ...  and it might be the total opposite too!     Quote   Its just not worth the time and trouble to mess about with joins on their big fully automated machine. And probably not worth messing about with joins on a one off coil either  ...  though I was looking forward to it. Not sure what it is really  ...  I could have just bought a couple of brand new larger cores from AEM and sandwiched those  ...  then I'd know they've been wound properly, annealed and demagnetised  ... ...  there's just something appealing about building something from junk.   I'll do these tests and then make a decision. Thanks so much for your advice Tony.
