Bill,
I know the windings need to be phased. I've never done this but I
gather all that needs to be done is to measure the voltage out. It
should be the same when two are connected in paralell. If less, then
one is out of phase. I don't know any other way to tell if my home
wound windings are connected correctly. I do know that there are phase
dots on some xmfrs that I have on the shelf.

Just a few comments.

If you are paralleling secondaries be very sure that
you are using identical twin transformers - even a tenth of
a volt difference in turns per volt will result in large
circulating currents.

Phasing is no big deal. Join together one end of the
two secondaries and link the two free ends with a short bit
of 10A fuse wire or thin flex. Apply power. If nothing
happens it's OK to parallel the two windings. If the fuse
wire disappears reverse the connections to one of the
primaries.
