I think a large Venn diagram intersects at this ponder.
I just found this circa 1950 French porcelain and brass beer tap tower.
The taps are Lison brassand feature knurled (castellated?) collars that look like they should be finger-tight, but won't budge. I want to loosen them and take them apart for cleaning, but don't want to mar the brass finish. Any ideas of the best tool to use?
(Some of you might be quick to point out that most brass contains lead, of which I'm aware. Interestingly, John Palmer, who has written a great wealth of material on brewing beer, started out as a metallurgist and has some pointers on how to prepare brass for food and drink service.)
