90 degree angle 4 chiller

[brewhaha]

Can someone tell me a good "homemade tool" for making a 90 degree angle with copper tubing (to make a wort chiller) I have the copper tube, and noted that when making angles the inside of the tube will touch itself, causing the "flow" to decrease. thanks for any help.

The cheeeeepest is a spring that has the inside diameter of the pipe.Keeps it smooth up to 90. #2 is sweat on a 90 fitting. #3 pipe bender from a HVAC supply house.

[brewhaha]

just a spring with the right diameter ? put that indside and make the bend and this will not crimp it ?

They sometimes come as a set of 5 different sizes. Try Sears tool dept. I have seen them there.
