Not all of us are tool hoarders even though we have been accused of being one. Like many others here I do have multiples of some tools. However they are not in "storage", "in need of repair", "for spare parts" or, "for just in case". I have multiple drill presses, grinders, surface plates, lathes, and a ton of duplicates as far as hand tools are concerned.. All of the tools in the shop are fully functional and are used on a regular basis. Some are setup for specific purposes.
One grinder is setup for HSS tooling while another is setup for carbide. The third is setup with buffing and polishing wheels. One of the drill presses is used regularly for deburring while the other is used for actual drilling. One lathe is used more often than not with a 5C collet setup while the other switches setup between a 3 jaw scroll chuck and a 4 jaw independent chuck.
I just gave away a small 1930's era Sears Companion lathe that I had restored for my brothers grandsons. At first dad and mom thought it might be a good idea, but after a more thorough evaluation they decided the kids were still too young to be taught to operate it safely. I hate stumbling over things that just take up space. If it has a purpose and is used regularly I'll keep it. If it's just eye candy or something I'll never use I don't need it taking up valuable space. There are still a couple machines I'd like to add to the shop like a Jig Bore and Toll Cutter Grinder. I continue to keep an eye open for them. Should I find either at the right price I would have to evaluate which machines would stay and which would go
I guess my point is that if you have the room, the tools are functional, and you have a use for them I would keep them. If space is a problem, or you're just saving something you'll never use because "it's neat" I would let it go to someone who could actually use and enjoy it.
