Derek, et al:
Birdsmouth mast info can be found here:

I'm sure that it's posted elsewhere on the
web, but this was the first site I found,
Thanks,

Also, look into aluminum tubing and/or flagpoles.
For my 2 cents, I'd encourage you to look hard at the 'birdsmouth' hollow
mast technique outlined in Woodenboat recently. Using strips ripped from
construction grade 2xX stock we built a 13 foot dinghy mast - did the
machining and assembly in a couple of hours, and ten bucks worth of hose
clamps makes the clamping problem disappear. Short lumber, knots etc are
easily dealt with by staggering joints in the staves. The end result is
light, dimensionally stable, appears strong, and certainly looks pretty. It
wasn't hard to figure out jigs for doing it with a handheld circular saw,
but any kind of table saw makes the process easier still. Software exists
out there (maybe in the vault?) to calculate the dimensions of strips
required for different diameters and wall thicknesses (and hence of course
tapers).

I have seen those discussed and, although I haven't tried them, in my mast
building experience (3 masts so far, 1 Gypsy and fore and main for Single
Handed Schooner), I don't think that the pcv would exert enough pressure.
