Anthon said:I suppose so, but then you would need a way to count the amount of twists you made. So you either have to count every turn of the power drill, or estimate the amount by counting small segments, so you would need to stop from time to time to check if you have the required amount of turns.
It would be nice to know the exact amount of twists you make without counting the actual twists on the wire, for the sake of simplicity and consistency.
What kind of precision do you need here? Does it matter much? My understanding is you want this for quadfilar winding. I very much doubt the number of turns per unit length matters much. There is no skin effect involved here. I would think the only reason for twisting wires is to help with compactness.Anthon said:I wonder if a coil winder can be used to twist litz wire.
For instance, you want 2.5 turns per inch, you take 4 strands of 1000 inch each, fasten them to the bobbin part of the winder, give it tension, and program it to make 2500 turns at moderate speed.
