I've been really busy the last 5-weeks, but managed to get back on the plenum project a few days ago. Got the edges all beveled and the halves welded back together. Started filing the welds smooth and a little 50-grit sandpaper works wonders on aluminum. Once the filing and sanding is all done I'll make 4 block off plates to cover the machined surfaces and glass bead it all over. When finished I doubt anyone will ever be able to tell it was very shortened. Lots of work, but a really enjoyable project.
