Simple Flange for an Air Pan for a drag car

[KKroger]

it is a 1970 Chevelle with a Fiberglass Cowl Hood, needed a larger flange for the air pan because the hole in the air box in the hood is too big. so I broke a piece of 18Ga 2"x2" and about 48" long then started with the Eastwood Deep Stretcher, carefully stretching the outside and then a little less a little deeper and so on... sneaking up on the diameter, I WANTED to make an Aluminum air pan for this but no time was allotted for the work.

Footnote on the Eastwood "Elite" Deep Shrinker Stretcher... it Works... Just... it was a gift, about 4 hours after getting it and assembling it the wedge block for the shrink jaws cracked in two... I e-mailed their Technical Support, after a bit of back and forth determining the part needed they shipped out a new set of Shrink and Stretch Dies... They need the corners radiused on both sets to keep from making marks with the pointy corners.
