Jared -

You've got it backwards. Type "L" tubing is not refrigeration tubing.

Hi Scott:

You are right, I mixed up refrigeration tube with plumbing tube. 
Included are the dimensions of type L:

We wind everything on to a 32 inch drum and straighten out the tube 
first (using soft rubber mallets with very light blows). Dropping 
tube directly from the box to the brackets only works if the form is 
roughly equal to the dimensions of your box of tubing. You will find 
it much easier (and get better results) if you wind from a large 
uniform diameter coil to a smaller intermediate form, where it can be 
straightened out further before placing in brackets. (Pancake style 
primary can be wound between stiff sheets of plywood with spacers.)
