Powering up Project Page 6

After talking to Chemlec he suggested to rewind the secoundary with copper foil. This worked great the foil I used is actually thin paper backed copper flashing. The roll to flashing was 6" wide, but I wrapped the end tightly with ducttape and used a electric chop saw [miter saw]to cut 1" of the end of the entire roll.I used 1& 1/2 inch paper masking tape, to insulate the edges of the 1" copper roll, befor starting the easy task of winding on to the transformer. This 1 inch strip of copper will handle the 20 to 25 amps easily.Gary Explained :The Inner Wire and Outer Wire that go Out of the Transformer Get Soldered

This is a photo Chemlec sent me along with the above discription.

Check out this "Frankinformer" Chemlec has built. This could give some guys big ideas. Chemlec says: Its about 2 Volts. (No Load, Open Circuit Voltage.)
Short Circuit Current is about 650 Amps

Instead of Wire, This is Flattened 1/2 Inch Copper water Pipe.
(Soldered Together in L Shapes, because it would be Nearly Impossible to Actually WRAP IT AROUND.)

But Copper or Brass Foil also works well for Quite High Currents.

Take care.....Gary

This shows the 10 gauge wire soldered on and the winding nearing completion.

Here is the quickest and neatest rewind!
