I used a good bit of Aluminum rigid conduit years ago, I don't remember having any trouble threading it or bending it. Maybe the contractor I was working for had special shoes for the bender.

I was quoted $.30 ft for 1/2" EMT this week, price was good that day only, 12 THHN stranded was quoted at $76/M

Now if I could only double my labor charge...

Few things are harder to put up with than the annoyance of a good example.
