I was looking for a 1/2" EMC hickey for some tight, ugly bends, but
don't see any in any catalogs. A few places still make rigid/IMC
hickeys for 1/2 but are these compatible or they too loose, and will
collapse thinwall?

I have a set of rigid hickeys and a set of EMT benders. A 1/2" hickey
WILL collapse EMT but there is a way to bend EMT with a hickey.

Fill the EMT with moist sand. Compact it well with some sort of
vibrator. An air hammer or jitterbug will work. Flatten each end and
either weld the end or bend it over using a vice and hammer.

Make your bends. It is practically like bending solid rod. Cut the
collapsed portion off and vibrate out the sand. An air blast will
remove all the sand.

It's a lot of work but it's the best way I know short of buying a
dedicated floor-mount tube bender.
