need to pull center of this edge down
I need to pull the the center of this edge down and create a stright edge from this view, as indicated by the white line. Do I need to stretch in the middle??? everthing else on the piece is pretty close to where it needs to be.

Mike, I need more info before I can help. Are you fitting it to a buck or FSP? or is it being made out of thin air so that it has a flow that you want? Is the arrangment proper, or do you have leeway there too?

Mike, I'd stretch where it's marked in this photo.
temp.jpg You're going to have to stretch in pie shapes the outer band gets more stretch than the next which gets more stretch than the next and so on. If you do a series like this and it still doesn't lay down enough, do another pie shaped stretch set on either side..

The top edge(on the left in this picture) must mate to another piece. The other edges need to be straight and in the same plane, ie if you set it on a table all of the edges would touch the table except the top. There is room to play in the amount of arc in the center of the price.

You could change arrangment some, pulling it down, then trimming off any excess, weld another strip to it, or like Kerry suggests, stretching the part. So many ways to do it, depending on what goals and limitations you have.

Hi Mike,
I would tweak it by hand to get it closer to your finished contours, then look at it again, do any shaping required, re-tweak. As you get closer to your final shape, make sure you get the metal as smooth as possible so that you can read it correctly. Lots of small lumps or discrepancies will effectively gather up and distort the surface making the final fit problematic. John www.ghiaspecialties.com

you could have probably made that piece out of a bigger sheet of metal , got it the shape needed , and then trimmed the sides to lay flat...
