draught tube

[Malcolm Walker <walker05@camosun.bc.ca>]

I am going to rout a drain hole for my scuttle vent drain.  Right now it
sticks down and rains into the space between the footwell and the front
fender.  I have the hose, conections, and ability to bore holes in my
(new) rocker.  

How should I cut the end of the hose to make sure it doesn't whistle at
speed?  I know there's a "trick" to it, but I don't know what it is.
