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 Attached image(s) |

My 2 cents, What gauge are you working with? It looks like 22GA or something. It looks too light for a seat pan. I'd use 16-18 GA Aluminum and make as much of the lip as I could fold and shrink, then gas weld the sections that are too tight to gather and smooth. Nothing wrong with making a couple of pieces to save work and a possible do over.
Then did you want the crease to tip up like that? The reason I ask is I've had metal change direction on it's own as I tried a tight tuck. I'd cut it and smooth it then gas weld it. Hammer weld it at this point. That's alot of metal to gather in a thght radius. Keep at it you get. Looks like your close. |
