I used this trick to evenly twist wires together for bifilar winding; 1, Trim the wire so both are the same length.
2, Clamp one end of the wires in a vice or have someone hold them with a pair of pliers. 3, Clamp the other end of the wires into a chuck of an electric drill (variable speed). 4, While holding the wire tight start the drill at slow speed and the wires will twist evenly. 73 Dave KD1NA Hi all, Quick question about the bifilar windings on the bifilar transformers like T6. How critical is the twist in the two wires? When I did T6, I was unable to get a terribly consistent winding of the two wires together. Build manual says they should cross over about every 1/2", but some parts of the wires ended up a little tighter than that, others less. On some of the windings when I wound the core, they more or less didn't pass over each other at all for one or two windings (tho they were adjacent). I'm assuming this is probably not super critical, but just curious. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
