If a person had two small 110VAC generators. Ganged the commons and

thinking 220v well pump, small transformer type welder, clothes dryer
etc.

If it would work, would the two gen-sets need to be the same size?

There is probably some simple reason why this is a really bad idea,

enough electrical background to see it.

No way to synch the phases between the two...


Well... there is a way. Couple the two shafts, so the gensets run in
tandem. There's nothing written that says two gasoline engines cannot
power the same shaft.

This would require that you establish the phase positions of each set
before locking the shaft coupling, and it would also assume that the
machines are not of the "writable stator" variety. Only very expensive
units with frequency control would have that feature anyway.

It would probably also mean running both in the same direction, so
something akin to cogged belt drive between the shafts would be more
appropriate than just linking them up head to head.

All in all, this would be a major project -- no time in my life for that
sort of cobbling.
