Lathe turned horn for PSD2002


The link below is from the High Efficiency Forum. Volvotreter is turning his own traxtrix horns out of MDF. I'm new to this kind of thing but how hard would it be to turn one to use a PSD2002 on top of a 4pi? Volvotreter has some info on his website but I don't understand much of it (yet!).

Anybody got any ideas, comments?
