[ATM] Secondary cowl

[Michael Lindner <mikell@optonline.net>]

I'd like to make my own spider/secondary holder, but I am faced with 2 
posisbilities:

1. silicone the secondary to the holder. This would require a holder that is a 
bit thicker (and therefore heavier) than I wanted. Also, although I've 
siliconed secondaries in the past without mishap, I'd still feel better with 
it held all around the edge...

2. Find a metal "cowl" that's the right size to hold the secondary. 
Unfortunately I know of no source for this, other than buying a secondary 
holder than throwing most of it away.

Thoughts?
