Anywho... on with the post... I made some security pins... I made one mushroom and one Spool... check em' out!

I put the pin in my dremel tool, just enough to hold it, and tightened it in... I turned the dremel on the lowest speed (about 10k RPM I think) and used a small hobby square file to file away the middle of the pin. I think they turned out nicely, and they work pretty good...
I'm sure this has been done before... just thought I'd post my experience with it...
