Re: Pickup winding machines?
I haven't seen the Schatten but supposedly it comes with everything you need, including a built-in counter.
Right now since I don't have a real machine, I just occasionally stop, scrape some of the insulation off the wire and read the DC resistance with the multimeter.
You don't change the movement of the bobbin to change the wind pattern because the bobbin doesn't move at all -- other than spinning of course. You guide the wire onto the bobbin with one hand and move it back and forth on the bobbin to fill it from top to bottom.
A precise definition of scatter winding varies some depending on who you're talking to. Some call it any winding that is not 100% automated, which means "hand-winding", even though a machine is involved in spinning the bobbin, because it is by nature a bit random since your hand is doing the guiding.
But some scatter-winding is more scattered than others. In the context of what I do (keeping in mind I have to be considered a novice having been at this only for about 10 days), I call scatter-winding when I move my hand backand forth quickly at lower speeds for a couple of seconds to guarantee some steep angles in there (a slight ball of yarn effect) once in a while during the winding process, just enough to break up the pattern but not too much or the coil might bulge too much in the middle for you to get the cover on it when you're done.
Technically, the wire always layers at least at very slight angles unless you never move the wire back and forth, which would obviously be a bit impractical.
