What did I buy?

[paulsomlo]

Have some unidentified objects from a recent auction purchase.

The black item looks like maybe the sector from an indexer?

The 3 cylindrical objects measure about 3.6" long, the knurled part is 0.5", largest diameter is 0.875, longest diameter is roughly 0.625. Two are countersunk on both ends, one is countersunk on one end only. These were part of a lot that contained mostly drill bushings.

The group of hardware includes a banjo bolt (?), another part that's threaded both internal and external and has a flare end, plus some brackets.

The brass screw is very well made, has a dome shaped head with a broad countersink, and a really narrow slot.

The red part is some sort of anodized aluminum nut, probably 10-32, with a nylon insert (locking?).

The items belonged to a machinist, who had worked in the aerospace industry.

The gold cad plated parts are custom brake line hardware, AN fitting part fits the hole on the bracket and the U clip holds it in.

Pins look familiar but I am drawing a blank for what... all 3 different diameters?

Agree the black item is sector from an indexer looks like it was only used in two places most of its life

This ^. To be more specific, they are for a rubber/flexible brake hose. The banjo bolt in the middle would be to attach the hose to a brake caliper and the other 3 pieces would be for the other end of the brake hose to attach it the frame and allow a steel line to connect to that end.

The 3 pins look like hardware from an Instron machine to me.

That threaded connector on the left looks exactly like an air fitting, as in medical air. The banjo bolt looks like it would go to an air or co2 tank, looks very similar to the ones that say “4k” on paintball co2 tanks. Maybe a valve to let off excess pressure when slightly overfilled?

Both of those brackets look like cord clips, they grab onto the neck of a power connector and then are screwed into the case of whatever device to prevent the power cord from being pulled out. Could be used for just about any kind of cable, line or tubing I’m sure. Red thing looks like what you said, a nyloc nut. Not sure about the rest

All three pins are pretty much the same - the diameter of the longest part differs slightly on them, from 0.622 to 0.625.
