High school shop class / metal lathe / two inch aluminum bar stock /
3/4 inch deep thin cutting tip / multiple cuts spaced same as
thickness as tool.
You should wind up with a 2 inch diameter cap with eight to ten fins.
This can be done for under $10 . Its harder, but a hacksaw and a wood
working lathe can do the same thing, only much slower.
I did this more for "looks" on a 4-1000 amp in the 70s, but I'm sure
with probably 10 times the surface area of the eimac caps, it did
"some" good.
