Tunnel sheet metal finished
I got the stainless steel part finished tonight, which wraps up the bulk of the work on the tunnel sheet metal. I still have some minor trimming to do and a bunch of nutplates to install, but the hard parts are done.
I was having trouble bending the large radius in the stainless steel. I finally got it working by forming it between a steel pipe and a large piece of steel tubing that was split down the middle. The mess was pressed together using a vice. The radius came out just right, though the angle was a few degrees less than perfect. It all fits fine once the screws are installed.
I'm pleased with the results. This is pretty much the picture I had in my head when I first decided to build the fiberglass flanges. It's nice to see it finally work out.

Sheet metal parts manufacturers 12/20/2012
Sheet metal fabrication is a classification of manufacturing processes that shape a piece of sheet metal into the desired part through material removal and/or material deformation. Sheet metal, which acts as the workpiece in these processes, is one of the most common forms of raw material stock. The material thickness that classifies a workpiece as sheet metal is not clearly defined. However, sheet metal is generally considered to be a piece of stock between 0.006 and 0.25 inches thick. A piece of metal much thinner is considered to be "foil" and any thicker is referred to as a "plate". The thickness of a piece of sheet metal is often referred to as its gauge, a number typically ranging from 3 to 38. A higher gauge indicates a thinner piece of sheet metal, with exact dimensions that depend on the material. Sheet metal can be cut, bent, and stretched into a nearly any shape. Material removal processes can create holes and cutouts in any 2D geometric shape. Deformation processes can bend the sheet numerous times to different angles or stretch the sheet to create complex contours. The size of sheet metal parts can range from a small washer or bracket, to midsize enclosures for home appliances, to large airplane wings. These parts are found in a variety of industries, such as aircraft, automotive, construction, consumer products, HVAC, and furniture.http://www.udtindia.com/tooldesign.php
