    i need to hand wind a toroidal transformer for a project im putting together. the schematic is here:

    im using 24g magnet wire. the toroid is rather on the small side. i attached a pic. it is 1/8 in thick. and OD is .230 In.This is the core that is recommended in the text. what is the best way to wind this? should i evenly space the primary of 48 turns with CTthen wrap the secondary on top evenly spaced?. or should i do a bifilar wrap? the only problem with bifilar is that the primary and secondary are different lengths. please give me your input!

    Evenly spaced winding should be fine with one winding on top of the other. Bifilar winding should not be necessary at that frequency but you could wind it bifilar until the shortest wire is used up and then continue winding the single remaining wire until it is finished.

    Are you going to be able to get all that, 48 turns primary and ? secondary through that little center hole? It' going to be crowded :eek:
