Dropped a brass helicoid cleaning jig on the concrete floor last Tuesday

I was working on a 50mm Takumar lens in my garage and the thing slipped right out of my hand. Landed on the edge and bent the alignment pin maybe 0.3mm, so now my focus ring has a slight hitch at the 2 meter mark. Anyone ever try filing a pin back to spec or should I just order a new jig?

Always thought filing was fine until I watched a buddy trash a ring doing it. Just order a new one.

If your buddy trashed a ring filing it, he didn't know what he was doing, the method's fine.

Yeah @jordan134, I get that. I filed a ring down myself once and actually cracked it too, so I feel the pain. What worked for me was just taking it slow and checking every few strokes against a template.
