Coil Question... need help

[Enigma516]

So I am experimenting with a few ideas we (myself and 2 others) have to build an efficient generator.

The coil we have designed is very hard to wind and i was wondering if I cut the wire (or lets say i ran out) an I just sand off the enamel solder the new wire and put some enamel or shrink wrap on the joint?

Hi,

It sounds ok that you want to solder and then shrink wrap the joint but maybe you wish to consider having some more flexibility for your generator:  bringing out those joints to the outside as if you deliberately have made taps on the windings, the advantage being able to use more or less number of turns, for adjusting output voltage etc.  Doing either way, the joints or taps will not influence badly the operation at all.

As Gyula said, it should be just fine to solder a new length into the existing one.
If the windings are likely to get hot in operation you could also consider a small amount of Polyimide tape around the solder joint. Polyimide is nice and flexible, but very heat resistant and a good insulator.
It's sold under the name 'Kapton' and its handy to have around the lab!

I love that idea, thank you very much

Do you have a good source for Polyimide tape ?
