There ya go, if ya have problems were here...
Drilling holes is what I was referring to in the Wiki article when I was talking about using a Jewelers block....
Which is a piece of solid steel 1 inch thick with a 5/64" hole drilled completely through it... This sits on an anvil and the rod is dropped in the hole it is cutoff and filed then you can tap on the peen with little fear of ever bending the pin.... Yes I have made one, but honestly the vice is faster :)
