The etch took far too long and ended up making a long thin needle.

The tip isn't too bad. It's within a factor of 4 or so of where it should be. Since I'm taking these photos using an emitter I made (that I couldn't inspect), I know I'm on the right track.

There are definitely issues with the EDS. Here's some gold at about 30,000X. Nice definition in the grains, but artifacts all over the place. Every EDS photo has the same repeating vertical pattern. The other pic is that weld again. Looks great except for all the artifacts.

Still lots of work to do, but the beam was rock solid for hours. Very encouraged by these results.
