I successfully wound my first 0.05mm wire guitar pickup rewind, but one curiosity- anyone know the reason?
This sort of rewind needs winding on a demountable former and transfering, as a hank of wire, into a trough. On demounting, there is a distinct banana shaped bowing to the hank. All I can think , there must be a twist in the wire on the spool or some bias on left hand traverse versus RH traverse. Despite pulling the wire off the supply spool tangentially rather than axially.
I just thought of another possibility. For this sort of very fine wire, instead of a final delivery pulley I use a tiny PTFE lump on a small bar. A hole in the PTFE squashed to form a sub-mm slot. Then a 15 foot run back to the spool (and a light felt slip clutch) to allow for any snatching. Because of room arrangement , to get a 15 foot run , the winder and so PTFE is set at an angle of 25 or 30 degrees rather than straight for-aft. Perhaps that puts a set on the wire.
