Today I stopped by Home Depot to pick up some air-conditioning stuff for the garage. I spent a couple hours connecting up a duct to the main plenum and then made a run to the garage with some ductwork. Installed one register today and will install another tomorrow after I buy more duct. It's already cooling the garage nicely with one vent; I am sure will only help.
I then started bucking some nose rib rivets on the HS. Oh what fun that is with one person, not to bad but I could see where two people would make it much quicker.
