Here is how I made those 180 degree bends. I would measure the total outside distance for the tube routing. I would then set a jig at that distance. The most important thing is to evenly heat the tube, as you bend it. As you bend it, you can see where you need to add more heat.

I use the same method for the "S" bend as well.
For the longer runs I also measured the total outside distance, and set the jig at that distance. I would then do each 90 degree bend one at a time.

The next part that was difficult was to get each leg the correct length. I just used the top of the fitting to get the legs trimmed to the right length. Since you already got the bend done, you just need the relative hieght of the fittings to get the proper length. You want to make sure that the tube is fully seated in both fittings when it is installed.
