Hi,
I have some large ferrite E cores, E55, that were damaged in shipping (ie. smashed into two or three pieces). I am planning on using gapped cores (2mm or so gap) inductors, so I was wondering how well these broken E cores would work once glued back together, since I need a large air gap anyway I think having a small gap where they are glued then the standard gap (slightly reduced to take into account the glued gap) would be ok still? I plan on just winding 10 layers or so of wire and then adjusting the gaps to the desired inductances.
cheers, Jamie
