Hello, 

Here is how I make loops...  I had a friend bend a nice loop out of
large diameter electrical conduit into a three foot circle, offsetting
the ends by one inch where they would come together. 

I then feed the copper tube into one end of the conduit, and force it
through the conduit by hand.  As I said, the ends of the conduit are
offset from each other by about an inch, so when the copper comes out of
the other end, I just pull the loop out...  

Poof, one finished loop, no sharp bends, and I can make loops all day,
each one exactly the same as the first.
