I Always Wondered How They Did That

You know, how they put the cheap metal axles in little plastic casters that go under Chinesium cabinets and such.

The rivets in cheap tools that let things move and spin.

If you have ever seen an Emergency Brake assembly with a foot pedal on it from a car from the 60’s to the early 2000’s, the part that you push down on swivels on a big rivet.

I always wondered how they made those and now I know. I ran across it earlier today and the process is called Orbital Riveting.

Orbital riveting is a low-force, noiseless cold-forming process that joins components by using a peen tool held at a fixed angle (typically 3° to 6°) to gradually deform a rivet. 
 Unlike impact riveting, the tool rotates off-center, maintaining a sweeping line of contact that progressively kneads the material into a desired shape with significantly reduced axial force. 

Of course there is a special machine with special bits that go in it they call Peens.

They can have different contours on the ends for specific types of finishes.

They can also control how far the end of the rivet expands and sticks out too.

That’s how they can allow parts to move and not fall off.

Here is the difference between Press Riveting and Orbital Riveting.

Just thought I would share, I’ve been turning wrenches for 45 years now and had never heard of it.

A Nice Ride!

Bluebird of bitterness., Our sweet little Scruffy, who left us in June for that great catnip field in the sky.

Scruffy.

Wild, wild West., The cartoon is what it’s like to home office around my place. The actual cat is Psycho Cat, hard at work defending the house from a flock of turkeys.  To her credit, not a single turkey has gotten into the house during her tenure, although keeping the doors shut probably has more to do with it than she does, and she certainly hasn’t been much good at stopping them from pooping on the patio.  Somebody found her on the road with a broken hip after being run over and took her to our vet, who patched her up and put her in a cage in his office waiting room hoping somebody would adopt her.  Turned out she was also pregnant at the time.  Mrs. whined about her for six months and after the kittens got adopted out, I finally got tired of hearing about it and told her to just go get the damn thing.  Fifteen years later, she’s slowed down considerably and no longer bouncing off the walls like when she first got us, which explains how she got named Psycho Cat, but we’ve been her servants ever since.
