For those interested in flared ports...

I've typed up a page about tube and flared vents. It might be of interest to those (including myself) who have no source of quality flared vents such as the FP kits from Adire Audio.

The page might help builders spin/rout/carve/sand their own flared vents. I'll write a small program for the equations and post the download link on my webpage.

Hth, corrections/questions are most welcome : )
