venturi vacuum generator plans

Hi,
I have a sherline lathe and want to build a venturi vacuum
generator, to be used with an air compressor. This will be
for vacuum bagging composites. Something like this:

or

Can I just drill a hole in a cylinder lengthwise, and another one
perpendicular to it (or at an angle), drill and tap for the 1/4 NPT
connections and be done, or is there more to it? What kind of
hole diameters work best? Should the holes be tapered?
Thanks,
Tom.
