The three secondaries can be connected together (paying attention to
polarity of the coils) to get 33 volts A.C. I'm pretty sure you can't (or
shouldn't) hook the two transformers together the way you describe because
they do not share a common iron core. It's been too many years since I
studied this to be definitive, but I suspect you could have "exciting"
results.

Forgot to mention this transformer came out of a laser cutter.
It's not a lot of use at these voltages and will probably scrapped for the
copper.

Had a sort out today and found two identical transformers 240v single phase
in
and three 11v secondaries at 50 amps on each.
I presume I can chain these up to get 66 volts which will give me 94 volts
DC which
will be ideal for the 110v DC treadmill motors running off a 100v 20 amp
