Coil, twists & turns

[Master303]

Hello!
I'm about to make my first coil for the bedini, and have a few questions ..

When twisting the threads, does it matter which direction i twist them?
and also, how many 'twists' per inch or cm?

I thought i should ask before spending 4 hours and alot of copper making a flawed coil

welcome master.


For coil winding it is advisabe to wind like so. Hold spool in right hand facing upwards. Start winding at the bottom in a clockwise direction (looking down on the coil). When you get to the top continue back down and repeat until you run out of wire. Try to end the last half foot at the top of the coil.

Thanks ren, but i couldn't wait and have already built it
i didn't go for the top 1/8 wound, but did a 'regular' wind with twists (also in clockwise direction)
Its only about 400-420 winds but it will do as a first coil!

i made 1 twist/inch give or take.. dont know if more twists makes it better?

here's a pic of the coil and the things i used to wind it

Being lefthanded I can tell you that it really did not matter for me which way I wound mine. I have wound them back and forth and they have all worked, as long as you properly pinpoint the North end of the coil and wire it from there on.

Now if you want to fine tune your coils, then it matters which way they are wound, the spacing of the twists, etc, because all these details influence the coil final parameters.

You're right amigo, a coils a coil. The only reason I gave specific instructions was to make it as easy as possible to follow the schematics.
