I'm sitting with 5 myself, one single stage I haven't used in years and one I need to put an engine on. Thing is, at one time I had 13 I'd rebuilt and ultimately sold most of them. IMO 7 is not a problem to most of us, unless you don't have space for them ;-)That’s great! I think I’m up to 7 blowers myself. Just can’t stand to scrap em! I always say I don’t trust any machine that didn’t see action in the winter of 78!
