G’day; Your square wire twists when you try making a coil?
Try gently clamping your square wire between two small pieces of
soft wood - lolly sticks would be fine, so that the wire runs
between the wood pieces to stop it from twisting. It will be
necessary to hold the mandrel rod close to the sticks when winding
the coil. There’s my ha’porth - and cheers,
