 To everyone:
 
 I talked to Walter about this piece. The idea is to divert the air around
 the flat spot on the side of the cylinder that has no fins. The part that I
 made that looks like a scoop, needs to be closed on the top. Or a box as Pat
 describes. I plan on working on the bottom area by the end of this week, I
 had to order some .050 aluminum to do the work.
 
 Regards
