Here are some more pictures of everything. As I understand it the 15kg spools of wire fit on the same sized spool holder, they're just twice the width, so the 5kg ones just use the (incredibly expensive) spacers in the photo
Yes tried it both ways but it does seem to be a solid lump so I think I'm wasting my time to be honest. I take it no one else has this setup in their Portamigs?
its nearly the same spool in all migs mine screw off anticlockwise you will just have to get tough with it
