Paul,   what is the recommended maximum degree of opening for the
louvers?  In the attached drawing  they are open 30 degrees.   Also,
I am thinking of making the side pieces out of .125 aluminum and
incorporating the crank.  What do  you think?   Jerry

Don't know for sure. Too many variables. My guess is about 45 degrees.
You would have to determine that by experiment. The first one should
be set up so you could go up to... say 60 degrees. That would then
become the research & development ship. It is of course your call.
If you make it 30 degrees and the pressure is still not as low 
as it could be you might have to remake things. Better to over design
on the first go around.
