If you have two 110V outlets, one on one phase, the other on a phase
180 degrees away, then you could access 220V.  wire one 3 prong male
plug connecting to the HOT pin, and connect that to one of the hot
pins of the European female 220V outlet.  Do not connect the neutral 
wire pin of the male to anything!  Wire the second 3 prong male 
connecting to the HOT pin, and connect that to the OTHER power pin on
the European 220V outlet.  Connect the European safety ground (if there
is one) to the safety ground of one or both safety grounds of the
3 prong male 110V plugs.  Check your work for safety, then plug in
the plugs into the selected outlets, then measure the European female
to see if you are getting 220V.  

Be sure to use wire heavy enough to carry all the current the outlets
are capable of feeding (determined by what size breakers are in use)
Breakers, for more safety, should be mechanically linked, so an
overload on one outlet circuit will shut both off.
and wire suitable for the physical abuse the envirnment can give.
Use 2/14 stranded cord for example.

     both |n's: no connection!

**I make no statement that this is thought of as being safe by the
fire dept, or electrical inspectors**!  Proceed at your own risk!!
