Because I am installing a new baggage hatch (see here
), I needed a new drip cap. In addition, I had several damaged drip caps. I bought online 4 drip caps, and two of them were in good shape structurally, but were dirty and corroded (probably from being attached to a non-aluminum sidewall of an SOB).
I decided to build a jig and give the drip caps a first-pass polish:
The drip caps were screwed to the board with pan-head screws (to avoid enlarging the rivet hole). I used the same board for the in-the-vice version and the on-the-benchtop version.
