I'll check the spool again for damage later today when I get home. The binding is on the outer edge where the spool comes in contact with the outside washer. That's where I put the oil and the noise stopped for the day. I like the adapter option allot. I don't like the current design. I'd rather have the welder not accept the smaller spools of wire (I have no need for them) than to keep this current setup. I might be alone in the thought though. The wing nut isn't too tight. If I loosen the wing nut the spool won't sit properly.
