You might be better to start with the softer tubing:
3003 is available from ACS for that application.
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.

Jabiru USA told me to glue in PVC water supply pipe. It is working pretty well
so far after 23 hours of flight test.
Good luck,

Jeff,
An option to tubing is 1/2" blue line cold water pipe available from the
aircraft parts department in your local Lowes, Home Depot, Ace etc. You only
need about 2' along with one 90, one 45 degree fitting and some five minute
epoxy. 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.
Best regards,
Mark

I'm at the point where I'm working on the fiberglass air plenums around
the cylinders. 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.

Lots of good ideas coming at you Jeff. 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. Fed
from NACA vent on bottom of cowl.

What a great idea! 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.

Thanks to all that replied. I got several great ideas. This should be a
fun weekend finishing up a bunch of little stuff!
