Two things.

1. How difficult would it be to make our own radiators?  This may be a silly
question.

Depends on how much of it you are going to farm out. If you
have your own furnace brazing equipment not hard. Or if you
accept epoxy bonding. All you need is a punch that can punch
oblong holes in 0.040 thick aluminum and a press for pressing
the end plates. Tedious but doable. [PL]

2. How difficult would it be to make our own pop-off vavle?  I haven't seen
one, but I would imagine it to be pretty simple.
