Square cores are the worst to wind... use your credit card to press every turn... you will see the benefit when doing the secondary.. when you start to think it got trouble just take out some turns and as it should have pressed the layer under it will be now easy to wind this turns again.. this happens every end of layer..

i was using varnish but maybe is not a good idea.. each layer using 29awg wire will have around 0,29mm... so if you lose the count you just measure it..

I already did use thew creditcard trick. Thanks for that good tip :-)
I agree that it is absolutly neccesary to make clean windings. The wire must have enough tenson and delay force on the system, but also not too much.
My tip of today: i use two plastic clothes pegs on the axis of the windrig. They provide enough delayforce and they take care that the axis do not turn back whenever i stop winding....

Cheers!

Today i finished assembling one vic and will start testing this morning with the coils i already had...

I get to wind the coils again...

I will be posting here somewhere soon a complete pLL circuit (updated)... for every one can use... i'm just missing the feedback part... for now...

How are the tests going Steve?

Ron
I always take a look at russ site but i never saw he doing other than epg stuff..

Alex site is there for a while.. he seems to be very interested into this as well..

well let make it!

I hope it will work

Hello bro i added a great feature to my coil winder ... that is a small dc motor that charges the wire to be rolled and when the wire is charged into a bobbin fixed to it.. its than used as the source of the wire for the main motor that where the bobbins to be wound sit.. adjusting the dc motor with a variac i can apply the perfect tension and wind the coils pretty fast!

Steve it's no different than Stan's, it's just flipped upside down, if you flip Adam's over it would be the same..
