Check out Paul Yaw's web site at www.yawpower.com and in the
pictures section
he walks through a very nice Pport construction.
Thanks for the pointer
Lynn. I've been to Paul's site, but never sifted through the pics
section. His article on flow testing shows some info on the PP as
well.
The entire void around the tube is filled with Devcon Plastic alumunum.
All
the way to the mating surface on both sides. File and sand dead smooth.
This
makes this area very stiff. No water can get through this area once you
have
finished. There is none in the factory Pport housing either. No water =
no water
leaks.
Wow, I didn't know that. I had
thought about filling the whole cavity around the PP, but figured that was too
silly to mention. So that should take care of the water leaks I
guess.
Did I also read that the factory PP
housing doesn't use one of the through bolts? I'm guessing the
port gets in the way if it's big enough.
The side ports in the irons are filled with Devcon Plastic Steel.
This makes me nervous, but I know that
Bruce shows contouring the 6 port high speed port with some sort of epoxy.
Still makes me nervous. I might not mind doing it for a temporary fix,
while waiting for the Racing Bead aluminum housings, which are set up for PP by
default.
The rotor housings are far more flexible than they
should be. I would not
weld anything to them.
Understood. It's really best that
I keep the TIG welder away from anything expensive :-)
Thanks also to Ken for pointing out the
filling of the cavity around the PP.
Rusty (still not doing this for the
RV-3)
