Little bit of micro-fillet-brazing and careful use of a small file.
I started working in the evenings, trying to get more (and more...) hours out of a day. It didn't really work > I ran my battery down and got sick. It's a guy thing...
The cylinder heads needed some fins, so a couple of chunks of aluminum ended up in the lathe chuck.
Four fins done, and four holes bored to fit over the stud towers on the right .
The middle of the fins was bored out, then cut into five sections to be glued around the stud towers with bondo. For some applications it really is a good glue .
