There are several panel designs in the Cat Girl folder that have pot holes
for Alpha pots (as I'm trying to use mine up). For example, check the
file in the Buchla type folder in the Yahoo groups Files directory. This
panel was designed for Alpha pots. As you noted above, the pot hole
diameters are .282in, and the Alpha pots fit comfortably into these holes
(with a tiny bit of wiggle room).
If you have a pot on hand, a useful tool is a drill bit template (not sure
what else to call these). These are typically a flat piece of plastic
with various hole sizes in English and metric units. Very handy for
determining the size of a hole for a pot (or switch or whatever).
