I come from a long line of pack rats. My great aunt and uncle's farm in Henry County, Illinois is a legend.
My grandmother's house had a 2-day auction. On the first day, we hauled stuff out onto the lawn, and all day long people said "I can't believe all this fit in that house!" to which we replied "Come back tomorrow--what you see is only half of it."
We found 3 army foot lockers packed to the bring with canceled checks. from HER father! I'm not kidding.
Recently, my father told me he has ALL of his tax files, going back to his first job. WHY?! "Well, some day I might want to look thru it." What the hell for?!
As far as "stuff" goes, I'm horrible too, and like most of you, I have too much stuff, and when I throw it away, I need it a couple weeks later.
Scrap metal goes on a pile next to my shop. I load it up and haul it away a few times a year.
Scrap wood: I've got problems with that. It gets stored here and there, and is usually in the way, but when I need it, I'm glad I've got it. I don't have a storage method yet, but check in the woodworking magazines at Home Depot: they very frequently have storage systems and solutions for organizing left-over wood.
And I also read a tip in one that said "don't obsess over every scrap of wood. Have a few for projects, and throw the rest in your wood stove." Great advise. I'm burning my brush this weekend, and will be throwing a bunch of old lumber on it.
Parts: A friend gave me a great bit of advise; if it's too good to throw away, but not good enough to keep, just go ahead and throw it away. As car guys, we ALL have stuff that falls into that category. It was great advise when I moved, and it's still good advise. I've thrown out a good bit of stuff, but I've also kept a bunch of things too. But what I've kept isn't random ****, it's parts that I know I will use, even if it's just "some day."
My problem right now is that I am horribly unorganized, and my shop and garage aren't finished... which means nothing is "set up," it's just "stashed there, in a manner I can work with it. Sort of."
Dad is coming down in April to help finish the shop and get it organized with me.
