What are the benefits of the wiggings couplings again? I am planning on

using

Earls AN 16 lines and couplings on my radiator and I think I can get

away

with all the lines and fittings for around $200 to $275.

The big drawback to large AN is stiffness and weight. The excessive

stiffness

cause high stress in rad fittings. One inch ID AN-16 might work but
it is not as good as 1.25 inch ID. One inch ID area is .78 square inches
while 1.25 ID is 1.23 square inches or 158% more flow area.

Maybe we are not doing a good job explaining our case Keith :-)

I might cough up the dough for four of them (or add the $200 to the

the plumbing?  The couplings are only part of the equation.

How easy/cheap is it to get thin walled aluminum tubing bent?

I am assuming that welding the couplings would be a difficult task.
Sooo, epoxy seems to be the alternative to welding.  That is cheap
enough.

Good question Todd. I notice a lot of the gyro guys use the muffler
bending shops. Not good cosmetically but easier to find
in most parts of the world. It can also be welded up from mandrill
bends.
