Now to measure for and cut the bosses, weld them to the plates, drill the reinforcement plates for rosette welding and get these installed on the trunk. (IMG:style_emoticons/default/cheer.gif)

More great work I see you have been up to.


Don't worry, I'll make it look pretty enough to install on that work of art of yours!

SWEET! I have a 914 /6! (but man, that little ".2" really adds some hp!) (IMG:style_emoticons/default/lol-2.gif)

Mike,
Let's plan a time to meet up. I'd love for you to see my project and pick through the machining goodies, but I can get out your way, too. Let me know...

I'm trying to sneak in an hour here and there to keep things moving along during the week. So this evening, I was able to get the flip trunk bosses cut down and welded to the reinforcement plates. Boring, yes. But it's all gotta be done.

Chris I would love to see the measurements, as I have the same setup in my shop, waiting.


Stephen -
Sure thing! In fact, I was thinking about you as I was doing this work, knowing you'd be doing the same install at some point. Once everything is in place and I know there's adequate adjustability and it all works as planned, I'll post some pics with measurements.
I can already tell you that to get things where I wanted them, the location of the hinge on my car is measuring out about 1/4" - 3/8" forward of where Andy has his.

The good news is that, near as I can tell so far, the specific location of the hinge (within maybe around 1" - 1 1/2"), isn't that critical. It'll be easier to document once I get it hooked up to the trunk lid and verify my assumptions about the geometry of this contraption!


(IMG:style_emoticons/default/beer.gif) Thank you Chris (IMG:style_emoticons/default/beerchug.gif)

Final steps in the flip trunk.
First, figure out the location of the threaded bosses and drill for clearance.

I removed all the paint under the stiffener plate and sprayed weld-through primer on the trunk lid and back side of the stiffener.
Then clamp for location. Very light clamping pressure, please!

I just tacked the corners of the stiffener plates and trial fitted everything.

I hadn't welded the cross bar together since I first wanted to get the entire assembly mocked up. Good thing, as it needed to be narrowed just a bit to allow everything to align nicely.

I still have to modify the part of the hinge plates that bolt to the trunk lid as they are still "Buick", as well as work out some sort of stop/rest for when it's in the full open position - which this picture isn't. It folds back much further and drops down lower behind the car. And I have what I think is a pretty cool idea for how to locate and secure the front edge... More on that as I get to it.

In the meantime, here it is: One (almost ready to go) flip trunk!

Big thanks again to Andy (Krieger) for having done this to his car. Seeing it in person made it a no-brainer decision for me. Thanks Andy!! (IMG:style_emoticons/default/smilie_pokal.gif)

Then I started on closing up the underside of the rear suspension tower stiffener I added way back when. Here're the before and afters.

Then I trimmed and seam welded the top side of the passenger rear suspension tower stiffening panel. The driver side is on the schedule for the next shop session.

I also got the passenger side front bumper brace welded in. As a BUB car, my chassis didn't have them. I salvaged the pieces from the '72 parts car.

In all, I think it was a pretty productive day.

Chris, this looks like a simple solution for mounting the alternate hinging hardware. I was thinking along the same lines for what I'm doing with Mini Cooper hinges.

Project is looking great. Keep at it.
