What are these tools?

Well, the bottom picture your right they are rivets. I can’t tell from the picture if they are hot or cold rivets. My guess would be cold rivets. Are they kind of soft metal? The fluted spirals are so they will expand for a better hold.

The middle picture, I have no idea! If the past owner of the items was like most tool users he made those for some special use and only he would know. A couple of them I could use from time to time for this and that! LOL

But, nice find!!

Not a lot of money.

On the second picture the bent pins and maybe the other pieces could be for depth setting and machine adjustment.

Other than the rivets, I have no idea.

I found out those rivet looking things are drive screws, used for attaching machine badges.

Bruce, that’s what I thought. The stuff in pic2 probably all had a purpose to the original owner but they will just get tossed into my odds and ends box.

Two of the calipers are dinky, about as long as my finger.

I think these pieces are somebody’s home made tool rest set. The smaller pieces all look like they’d fit into the upright (center post) and the screw tightens to hold them. Longer pieces for turning inside deeper items (bowls?)

Interesting idea Joe. You can’t tell in the picture but they are too small for that. Here is a better picture where you can see the scale. I realized that two of the pieces seem to fit together.
