Thanks Dennis and Alain!! Pat, let me begin by saying that I'm not a pro. I have tried many ways of bending pipe with not very good results. I've tried aluminum, both solid and hollow. I've tried plastic, both solid and hollow, with and without heat, but this way seemed to work the best so far. I took a T-Lite candle from my wife's stash. With the T-Lite burning, I rotated the area that was to be bent over the flame like a rotisserie. I heated it slowly, not too close to the flame until the plastic was almost putty like. Bending the tube too soon before it is soft enough results in kinking. Once I achieved the angle that I was after, I held it still until it cooled enough to hold its shape. A few stubborn spots required sanding to make them look right. I was pretty satisfied with all four pipes on this build using this method. This may not be the best method, but it works until my wife runs out of candles. I hope this helps...Brian
