Pushnut Removal

Pushnuts can be an aggravation to remove. They can sometimes be coaxed off non-destructively, but they often have to be cut or broken for removal.

I encountered an awkwardly configured pushnut recently on a string trimmer's recoil starter, and I tried using a small diamond burr to cut through it radially to break it. That worked fairly well. Here's a view of the work in progress.

The diamond burr was not a terribly effective grinder, but it was adequate to wear away enough metal that I was able to pry under the pushnut and snap it apart, like so.

Success. And I didn't make a great mess of the adjacent hub.

So there's a reasonably effective way to deal with some pushnuts.
