I was given a Miller Cricket from my brother in excellent condition. The problem I am having is buying a spool of wire for it. The Cricket has a large diameter hub but all 1 - 2lb spools in the stores fit a small diameter hub. There seems to be no option on the Cricket to change to a smaller diameter. The only spools that will fit are the large spools and I don't do enough welding to justify a spool that size.
Does enyone have any ideas or has run into this problem?

Thanks for any advice you can give.
