Re look at them? No, I've seen them all MANY times. Thought of digitizing? Yes, IF I can figure out a way to do it IN the Carousels, or find someone to do that without charging a zillion bucks! See, these are arranged in shows. Among other things my dad was an artist in several areas (painting, scultpure, photography, music, etc. ) and also a student of all these fields. He used to lecture on various topics in those areas, and the slide shows were part of that. I also have his lecture notes... so I need to preserve the shows to match. I've thoughte about using my DSLR to take pictures of the slides as projected onto the screen, but that is not the "optimum" way to preserve the quality to say the least! Anyone know a service that can do this at a reasonable price?
It's possible they might have been sources for a better "antiquing" substance for brass, though.... several of his machines were about the same size as those beasts. He was an ME and specialized in rigging. He used to buy these as scrap and use pieces of them to build specialized ones for his rigging business. MY father (died in 1988) left me among other things his 35mm slide collection... about 60,000 of them from all over the world, mostly arranged in Kodak Carousel 140-slide trays in themed shows. They mostly fill a walk-in closet (along with the projector, projector table, screen, etc.).
@max: "Will this ever end?" Only when EVERYTHING does..... Tools break, wear out, or somebody makes a much better one or invents one that fills a need you didn't even know you had. There's ALWAYS a reason for more. It could be worse: my late father-in-law was a tool collector, but HIS were cranes, bulldozers, etc! He had 4 acres of them when he died.
I just got another HF flyer with the 6" calipers for $9.99 -- but two 6" calipers is enough for me, I'm waiting until they have a great deal on 12" digital calipers.
BTW, I think you haven't been keeping up with the times; IIRC, you're in Huntsville, which has a HF (I guess links aren't allowed, so try www.harborfreight.com/al/huntsville.html ) HF has been opening a lot of stores recently; I hope they don't open too many (and then have problems).
