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?


Pretty sure Nick Muller already did this and has the dimensions on
his web site...maybe Don Foreman will post link....
