The bellmouths were just another "looks right to me"  part.   Turned with a hand held tool on a lathe (plywood) then covered with epoxy resin.

Thanks. I was hoping for 1/2". :-)

Did you just use a constant radius lip, or go whole-hog with an eliptical?

Pretty close.  Think I ended up with between 5/8" to 3/4" clearance.   I did
some pressure drop studies using a vacuum cleaner and was amazed at how
close you could get it without any apparent restriction.

Hi Tracy,

How close are your bellmouths to the outside wall of your 'shoebox' on
your Renesis? I'm trying for the longest runners that will fit in the box
(constrained by the cowl, of course).

Thanks,

Charlie
