The fun part is that I need to stretch both flanges the same amount to get it to curve and match the inside of the roof skin, but not twist to one side or the other. I started with one of the short pieces. It actually wasn't as bad as I thought it might have been.
Here's the 'before and after" shot. Attached thumbnail(s) |

And the piece as it fits approximately where it needs to live. Lots more to do but getting there.

Would you stop coming up with design elements that I love so much? (IMG:style_emoticons/default/wub.gif)
Seriously, such a good idea. |

Today was fabbing the pieces needed to support the roof above the targa bar. These are needed to fill the gap that's created when the seals are removed. They are critical in that sizing them determines where the roof sits and sets the window seal angle.
Here's what I ended up with - a little channel that will weld to the targa bar and to which the roof will bond. The channel's open front will be welded closed and the rear will be sealed by the panel that closes the gap across the width of the roof and the targa bar. Attached thumbnail(s) |

I worked on shaping the remaining pieces of the X-brace channel. Still a bit of fine tuning but it turned out pretty well so I started in on where, exactly, the brace components will sit. There's some flexibility in where the ends sit.
As John Mayall sang, I have a little bit of "room to move"! (IMG:style_emoticons/default/aktion035.gif) https://www.youtube.com/watch?v=zLp0AsKXMEs Really, it's about positioning the X-brace so it sits close, but no too close, to the underside of the roof. Attached thumbnail(s) |

Today's work was to remake the pieces that sit at the outside edge of the targa bar. I wasn't paying attention and the first version didn't match the angle of the sail panel. These do. Also note that the top of these pieces need to align with part of the roof where the seals would usually mount. A bit of what looks like a wonky angle but that's what the roof said it needed and now it sits flush against these. It should work fine as the bonding surface.
I went ahead and tacked them into place. Things can move around a bit and I REALLY need to nail the exact height to be sure the window seals sit where they need to sit. Attached thumbnail(s) |

I hadn't thought about it when I saw the first picture but that really does look much nicer.

Is bonding on a stock roof really what I want to do? (IMG:style_emoticons/default/idea.gif) It just seems too easy and not in keeping with the vibe of car.
I had an idea for a different approach: A steel (916-like roof frame with drip rails) say 4" wide on the sides, with a bonded carbon "center" panel. Anyway, I broke out the English wheel to see if I could pull it off. Of all the metal shaping things, wheeling compound curves is the hardest for me. This piece has a bit more to go but I think I can make this design work. I'll invest a couple more days and see if I can achieve (close enough) symmetry on both sides. (IMG:style_emoticons/default/smash.gif) If so, it'll likely be a go! Wish me luck... Attached thumbnail(s) |

Ha, I shoulda started a pool to see how long the fiberglass would last.
I hope you know you can never stop fabricating as I live my metal life vicariously through you. Keep on Keepin on |

(IMG:style_emoticons/default/aktion035.gif) Maybe we should start a pool—but one thing is certain: the roof is gonna help stiffen what will be a seriously powerful and quick 914... |

@djway - I doubt anyone would take a bet that implied I WOULDN'T change my plans so I'm pretty sure your vicarious metal life is safe for a while... (IMG:style_emoticons/default/laugh.gif)
Today was a LOT of looking, measuring, head scratching and only a little actual work. It all getting a little more complicated than I initially expected, but then that's really not a surprise. The Devil is in the details, as we all know. (IMG:style_emoticons/default/happy11.gif) Hey, who you laughing at, mofo? Anyway, I wasn't making any real progress with that side panel because other than the front corner of the windshield pillar, there are no other reference points to fit it. So my new plan of attack is to work from the outside in. Meaning, first get the drip rails and rear of roof "closing panel" on the car. These pieces will set the overall width and length, as well as square things to the chassis. Then it'a a matter of shaping and fitting the steel side and rear pieces into this frame. OK then. Here's the new rear "closing panel". It will need to be trimmed to height and have a return added to which the roof will fasten. It's encouraging when the fit turns out so nicely.

It makes for a much simpler and cleaner visual finish, IMHO. But, I do reserve the right to change my mind! (IMG:style_emoticons/default/shades.gif) |

suggestion as I had a lot of time thinking about this one. I Planned on putting a flange on the top Lou, nd then bonding the steel 944 top onto the flange, and then crimping the skin over the rear upper flange.
Love the idea, glad your doing it your way. |
