Help me JOHN KELLY you're my only hope, Tuck issue Options

[scotty b]

I'm making a seat/rear fairing for a cafe racer conversion. I folded the lip on the lower portion last night using my bead roller with tipping dies and then shrunk it to smooth it back out. My problem is at the rear where the curve gets really acute. I had 2 small tucks on the side ( see pics ) that came out fine but the one at the dead center of the apex was less then satisfying to me. Did I do something wrong on the larger one or is it just not that possible to get it smoothed out? Despite all of the metal werk I have done this is the first time I have attempted a tuck job. At this point I'm happy with the results and will fix the fold with a vouple of spot welds but what about the next time?? How can I get a smoother tuck?

Thanks

Rick it actually is 18 gauge sheet. In the past when doing something like this I would have simply cut a slice in the center of the tuck, folded it in, then cut out the overlap and welded it up. I decided this time to do it the "hard" way, and see if I could actually finish it out without welding. As for the pick marks, I used the pick end to tighten up the tuck in an attempt to prevent it from walking back out. Once I had done this I was afraid that I had made it too tight which sounds like what you and Rick are both saying. I also had planned on making it out of aluminum, BUT I don't have a sufficient tig welder and my attempt at gas welding aluminum a few years ago was not pretty (IMG:style_emoticons/default/icon8.gif) On and no hammerform. I did it all with the tipping dies and shrinker.

Is the tuck shrinking video a new one? I have your first video that focuses on the flares.
