Ernest, you are right "Welding" on a bung could cause the seams to loosen although a good TIG welder could do it.  However, brazing on a bung uses considerably lower temperatures - given the heat in that area,  I personally would not use epoxy.  You can probably find a radiator shop that can do the job for you quite reasonably or use the HT200 aluminum brazing material if you do it yourself..

Subject: [FlyRotary] options for modifying radiator


I've got to add a way to attach the in and out hoses to my radiator (I'm
going to be using 3/4" hoses, Bobby).  I've assumed that about the only
way to do this would be to weld on a nipple.  But pouring that much heat
into a radiator presents the possibility of damaging it.  Are there any
other possibilites that don't involve heat?   It would be neat if
someone made a gasketed, threaded insert that would expand when an NPT
fitting is inserted.  Insert it like a grommet, then add the fitting to
lock it to the sides.  An angled lip would pull the flange down onto the
gasket.  Anyone ever seen such a beast?
