Anyone here make their own laminated core transformers?

(1/1)

Just looking for stories and experiences..I'm planning on making several. Would like to hear about what you've done, especially if you made any fixtures for assembly, varnish dipper, coil winding (bonus points!), made your own bobbins, etc..

It's not worth the effort to buy laminations, wires of wires diameters and so on...  you can buy ready made transformers for reasonable prices these days.

Also, I'd rather go with toroidal transformers any time of day instead of plain transformers. Less weight to deal with.

Is the project here to make specialty high voltage transformers?

If not, it probably isn't worth your time. If you think it is, you can probably buy a used pole pig.
