 do you guys do that??! >>

Usually, when you buy a roll of refer tubing, it is already coiled fairly 
close and you just gently adjust the diameter of the turns one at a time.  If 
you are using tubing that is not new, you could start by winding it in a 
helix around a bucket or large pipe first and then manipulate the turns one 
at a time
