My dad made a gate for our garden out of 1/2" bent into a "U" and based in a wooden base.

Have seen plans for a 1/2" EMT hammer dulcimer.

Used some 3/4" EMT as a makeshift clothesrack for a while - it never bent like the expanding chrome ones did... of course I suppose I could have brought the laundry up a little more frequently...NAAH.

Replacement handle for an air compressor.

Once had a "cat tower" that wouldn't lock securely between the ceiling and floor - pulled out the "pipe" and recognized that particular type of galvanization pattern... you guessed it - 1/2" EMT. (Even labeled w/ UL!) Just stuck in a longer piece and everything was fine.
