Subject: Is the cowling sacrosanct?

Jim stopped by to have a look at my Delta project (and the lack of 
progress thereof).  I pointed out that I plan to mount my second 
radiator directly to the engine cowling.  He didn't think it was a good 
idea.

I still don't think it will be a problem, because I have such wide open 
access to the engine with the hood open.  It'll be just like a fender 
mounted component in a car.  The duct will also make the cowling 
stiffer.   The nose provides a portion of lift in the Delta, so mounting 
a radiator there will provide for an extremely short load path.

Basically, I'm looking for a good reason* not to use the cowl as a 
mounting point.


*"We've always done it that way" is not considered a reason for this 
discussion.
