I have formed bends by making round plywood discs as formers, a smaller diameter disc of the same thickness as the tubing, bolted between 2 larger side discs, prevents the tube collapsing when you make the bend. Discs easily made with large holesaws.

Use a short piece of pipe, the 45 and then a longer piece to blast air on the right side coil (1,3,5) and then a very short piece, 90 and another short piece to blast air on the left coil (2,4,6). Use the 5 minute epoxy to glue it all in. Don't forget to sand all surfaces before gluing them in. This is what we use on all of our installations. If you'd like a picture please e-mail me off-line.

I have half in round 6061-T6 to make the tubes. How in the world do I bend the tubes as pictured on the JabiruUSA web site? All the tube benders I can find only bend up to 3 eights inch tubing.

If you want to get a bit more complicated, and direct cool air on other electricals, you could do this. Blast tubes to both coils, both mags, and the regulator.

I wish I had asked for help on some of these things earlier. I probably wasted (no: used) a lot of time trying to educate myself that I didn't have to. I actually thought of using other materials for the tubes myself, but I thought of copper elbows. It turns out that the1/2 inch copper elbows are a lot bigger than 1/2 inch and were too big for the 1/2 inch AL tube. And that doesn't even consider how far apart the two metals are on the galvanic scale. I didn't think of the plastic pipes probably because I already had some left over 6061 tubing available. I used it elsewhere for electrical conduit.
