making the 2" hole in the 1/4" steel plate.

Plasma cutter. A trailer place might not have one, but any halfway
decent steel fabricator will.


Is the best tool to cut through the steel a bi-metal hole saw? Should it
be 50mm (advertised on ebay as 50mm/2") or 51 mm.

OD usually, but it's a hard job to get real accuracy out of them
anyway.

Acrow props are quite heavy, as they're specced for a serious loading,
more than you'd need for a trailer leg.
