Peening

[Loren Marcus]

Is there a video to show the best way to peen a bushing?

Thank you

Does this help, Bushing Using Hand Tools

And or what is peening?

Peening is the act of deforming a metal part by striking it with a hammer, or using a punch type tool and striking it with a hammer, against the part.
Usually it is dome to enlarge the part on the end, so it doesn't fit back through an opening.
A "Ball peen" hammer has a round end designed for this purpose.

I use a special rounded punch. A light tap will spread the brass without smashing it. There are several different sizes on my bench but go easy. Lay the plate on a flat steel surface if possible. Make up a stump for jobs such as that.

Loren, the word peening, as mentioned above, is a word used in describing the spreading of metal by pounding it with a hammer. In bushing it is not a good idea to use a steel hammer to drive in a brass bushing because of the possibility of peening ( deforming) the bushing. It is much better to press a bushing in because it keeps the bushing straight in the hole and it does not deform the bushing. Some use a drill press or flat jawed pliers to do so. Bushing machines or mills are the best way to press them in. Occasionally it is impossible to press the bushing in. A brass hammer or a soft metal punch can be used in that case. A hardwood dowel is also a good tool to use in tight spots.

Ok, I understand it know, I thank you very much

As stated above not everyone peens bushings.
If the hole in the plate is sized properly, the bushing will hold in place just from the tight fit, - done.
If the bushing is a looser fit, enough to possibly fall out, some will peen them to ensure they stay put.
Others use Loctite, which is sacrilegious to some, but works well if properly applied.

I use dapping tools for some of the smaller rivets and click rivets. I also have a small 6" "claw" type hammer that I have filed the head to a slight convexed shape then polished the surface. Works great for larger type rivets and such.

Makes good sense. Thank you
