Attached are links to renderings of the plenum design I am (slowly) building.

This bolts on top of the lower runner assembly, right?

 

Depending on how nerdy you are, get yourself the trial of SolidWorks, and 3d print that s.o.b. out.  Heat shouldn't be a problem there.

 

I would estimate your material cost in aluminum to be almost $175, and then the machining and welding your design requires... So 3d might be a viable alternative.

 

  You can use Rivnuts or Heli-coils for all your fastener points.  As a bonus you can do the right thing and print out trumpets that extend off the rounded plenum walls- no corners.

 

Btw, I had thoughts of doing this before the itb project...

FYI there are extrusions for plenums out there that are  D shaped in their cross section.  I did the calculations on plenum volume once and the smaller of the 2 sizes available made the right volume. Do a search on plenum kits or parts

Thanks for the input. I am glad that the renderings has encouraged discussion here and on Facebook.

I must have been suffering from a major brain fart to not think of using the rounded extrusions. I have already changed the design to use the "D" shaped aluminum.

This project is progressing slowly, but surely with the helpful input of all.
