Hoarding? Or just collecting stuff that might someday be useful.
Part of the inherited stuff here is in those drawers on the left, in the photo.
One drawer is full of hose clamps, size from fuel line up to AC duct.
One drawer is full of wire brushes, many are scrub-brush shape so limited in application. Over 20 years I've worn out maybe half of what was in that drawer. (And bought several more useful brushes).
In the lower small drawers: more barn hinges and barn-door handles than I'll ever use.
One drawer of used garden faucets. I rebuilt a half dozen with new seals. Now I'm good for a few decades.
One drawer, every kind of garden hose repair coupling.
And chain repair links, clevises, tie-down hooks, wild miscellany. I won't discard what remains after I sorted to save what's useful.
It can take more time to find components, or to sharpen an old tool, than the actual time it takes to do a project. But that's still time saved by not having to go to town for anything.
Another photo of inherited not-hoarded

stuff. There's set of drill bits in the pictured stall for my corded or cordless drills, and a second set at my drill press in a different shop room. What's in this photo below is excess, in dead storage. Like I said previously, Dad couldn't pass up buying anything he could get for less than 3 cents on the dollar whether he had a use for or or not.
