Subject: [FlyRotary] It's Ed's fault
:-)
Greetings,
"Yee of little faith"
here decided to believe Ed, and not install bleed fittings in the top of my
evap cores. Today's log follows. I imagine the mechanical pump
would have done the job in several iterations of running, but I don't want to
have to go through that every time I drain and fill the system.
Fortunately, I left the cores clecoed to the mounting brackets for just such a
reason. I'll be welding 1/8" pieces to the top of one tank on each core,
and threading it for 1/8 NPT. If I can find a nice petcock locally, I'll
use that, otherwise, just a plug for now.

Did
a lot of fiddly things to get ready to fill and start the engine. Unfortunately, when trying to fill the
water, I couldn’t. The EWP wouldn’t pump, because it wasn’t primed. It can’t get primed, because there’s
no water in the evap cores.
There’s no water in the evap cores, because I listened to Ed and didn’t
install fittings in the top to bleed out the air :-) Installation of the bleed fittings is
under way. There was also a
pinhole leak in one of the EWP flanges. I need to fire my welder. It has now been “JB welded” within an
inch of it’s life. If it leaks
now, I’ll just have to throw it away.
Cheers,
Rusty (Ed, you owe me a beer
<g>)
Gee, Rusty, If I had know you
were really planning to use an EWP I would have strongly recommend bleed
fittings. Everyone knows those EWPs can hardly pump sufficient flow to
remove heat, much less air bubbles {:>). (Just kidding of
course)
Actually, I've never
encountered that problem (water pump wouldn't prime) probably because my water
pump is the lowest point in my cooling system (Plugs Up). So basically
if there is any coolant in the block at all it will get
pumped.
But, show up at Sun & Fun
with your RV-3 and I'll buy you two beers {:>)
