Today was about closing up the main hoop and fire wall.
I started with this little spot above the fire wall arch.
First, cut a paper template (and remember to account for the flanges!)
Then I used the bead roller to fold the flanges.

Here's the template and the finished piece.
It's funny, I talked with Tony (Cracker) today and we laughed about how these build threads show all the pics but there's no real evidence of just how much work it takes to get from what was to what now is.
All told, this little piece took me about 2 hours to make.

I was feeling pretty good about fabbing sheet metal so I figured I may as well get started on the inner fire wall.
Template, metal shears, fit, fit, fit and...
Well, OK... There will be some more fitting. But it's looking good so far.
Next is laying out and rolling in some sort of bead to help it resist oil canning and to add some visual appeal.

Did the final trimming and fitting of the lower fire wall. The electric shears are awesome and make quick work of getting a clean cut right to the mark.
Got the final flange bent across the top. Happy with the fit.

Here a shot of the fire wall and how it's fit with the little filler piece made earlier. Almost looks like I know what I'm doing...!

Next I started on the boxing in of the main roll hoop, this time on the engine side.
I made paper templates to figure the location of the holes then used the dimple die to pretty them up.
These slide up out of the way to allow for the hoop to be welded to the pads that are welded to the longs. Then these slide into place and get welded in as part of boxing in the engine mounts.
Can't tell you what a relief it is to fit the second on and actually have it all fit!
Remember, this is the first time I've tried virtually any of this sort of fabrication and I hope it encourages anyone who's thinking of giving it a go. I just take my time, measure 100 times and only post pics of when it actually works out!

Continuing work on fabbing the parts needed to close in the roll hoop. I made up the front 1/2 of the "cap" on the passenger side.
tygaboy
Dec 28 2016, 04:36 PM
Then I started on the final part. Here's a look at how I approach making the paper template. Once this is fitting as desired, it's transferred to 18 gauge and formed / trimmed til it fits. Easy, no?
Well, except then I get to (try and) make a mirror image for the other side. That's always the "interesting" part...

The ADD kicked in again and I got distracted with other areas of the car. I've been debating what to do re: keep vs lose the trunk. It would appear I've decided!
If you've seen Tony's car, you'll know why I think of this modification as partial "Cracker Replica".
Imitation being the sincerest form, and all that.
It certainly eases access to, um, everything!
And yes, there will be roll bar/chassis stiffening added.
This will never be mistaken for a sleeper but I do want to be able to store the top so while I still have trimming to do, I will leave a lip all around the edge as I plan to make a removable "trunk tray/liner" to provide a least some protection for the top.
tygaboy
Dec 30 2016, 03:57 PM
That darned ADD! Once the trunk was out, I played with an initial design for the console. This essentially gives away the styling cues I'm going with throughout the interior: a very industrial, trellis, open architecture-y look that leaves all the mechanical elements exposed.
A looooooong way yet to go but it gives you the idea.
Cracker
Dec 30 2016, 06:19 PM
That does look familiar...glad to have you aboard! After seeing your fabrication skills - I am very much looking forward to seeing the greatly enhanced "Cracker Replica" version.
Just make sure the cockpit fits a 6'5" frame (Um, drivers side...)!
Happy new-years to you Chris!

I did the final trimming of most of the main open area, leaving that lip for the removable cover I'm planning. I still have to remove the front of the trunk wall above and outside of the suspension consoles...
Then I started on fabrication on the stiffeners for between the consoles.
Another arch... Imagine that. The top bar will also serve as the point from which a bracket will extend forward to support the stock engine cover latch.
I'll end up plating around the consoles so neither of these are quite where they'll end up. But close enough for me to determine what I want to do. I have an idea for a panel that will sit between them. It'll add some additional strength as well as visual appeal!

That cutting up and gifting the pieces from the other car took up a bunch of your fab time.
Looking great though and you are further along then I am.

Totally agree with Ben. However Chris your build is mind blowing.
The shifter console structure is a work of art.
Truly unique approach tying the chassis together in the manner you have.
It will be very cool to see this 914 in motion!
tygaboy
Jan 2 2017, 04:26 PM
Did the final removal of the trunk and up around the suspension consoles. Then I started fabrication of the plates that will reinforce the consoles in prep for installing the stiffeners.
Man, doing this stuff takes forever...
but it REALLY opens things up and allows for optimal location of the rear part of the stiffening bars.
I have an idea for the trans mount cross member, too. Should be pretty neat looking and add some strength.

With the removal of the trunk sheet metal complete, we get to see a part of our cars I've rarely seen: The point where the long stops and sorta has a wimpy tie into the rear shock towers.
Gotta do something about that.
tygaboy
Jan 8 2017, 02:01 PM
So I fabbed up a 1/8" plate that I bent and trimmed to fit. Here's an almost final fit.
I'll cap this off with...
tygaboy
Jan 8 2017, 02:02 PM
... a cap! Again, not the final fit, but you get the idea.
I think I'll box this from the inside edge down to the bottom of the long, making kind of a triangulated box.

I started messing with the intake. In running the Mass Airflow Sensor (MAF), I have to follow a few rules about where the sensor has to be, relative to the throttle body. I need a minimum of 10 inches from the throttle body, six inches of straight tube, the sensor has to be set at between a 9:00 - 3:00 orientation...
So, a bit of a puzzle and a bit of mystery?
A puzzle is when you have all the pieces and "just" have to figure out how they fit.
A mystery is "profound, inexplicable, or of secretive quality or character."
I really do have a bit of both going on here: I have some pieces, I have some pieces yet to make.
But I swear, as I start looking at how I'll have to build the intake to meet the above criteria, fit the stiffening bars, run a suitable air cleaner AND make it all fit under the targa top (which needs to somehow still safely store in this area...) ???!?!?!?!?
Well, it's currently a flippin' MYSTERY to me!
Certainly, the "secretive quality" part...
But fear not, World. I will solve it.
ps. I'm loving how this is starting to look. That's a 4" intake tube. Small children and pets will need to be careful they aren't sucked in!

How big is that motor? It wants 6" straight upstream then 10" downstream to TB? Interesting. That seems a little restrictive since the air shouldn't be moving super fast so the velocity profile should be pretty uniform. A while ago I actually took a similar style [thermal] sensor and offset mounted it in a duct bend to measure the effective average flow but that took a fair bit of analysis.
Maybe just some stiffener tube scalloping would make everything fit nicely. It does look pretty cool now!
Thanks for showing pictures of the end of the long. There is a thread around here with some, but yours show the attachment issue much better.

It's a 6.2 liter. First, I'm no expert so I'm only quoting what I'm finding on line. Here's a pic of what came with the blade style MAF sensor re: what needs to go where.

Feeling boxed in? My rear shock towers are with you!
After a bit more head scratching, I decided to go a different route: I wanted to run one piece of reinforcement from the long up to and around the tower. Since I'm not exactly sure how the removable trunk liner will work, I opted to retain the lip the runs up the tower.
So I sliced a channel for the sheet metal.
tygaboy
Jan 15 2017, 08:09 AM
Then I made a pattern and fit a piece that slips down into that channel. This is the driver's side, which I just happened to tackle first.
I tacked it in, "persuading" it to wrap the tower, plug welding as I went along.
Then fit and tacked in the top part. It's plug welded, too. I still have to final trim the top part where it wraps the tower. I left it a bit tall for now as I may plate it to the Tangerine Racing raised rear shock towers, once those are installed.
Then I need to add a bottom piece to close in the box and seam weld everything.
tygaboy
Jan 15 2017, 10:44 AM
Let me back up and show a bit more detail.
Here's the pattern and the trimmed and bent piece, then how it fits before I start tacking and wrapping it around the tower.
Exciting, I know...!
tygaboy
Jan 15 2017, 02:38 PM
Tacked and plug welding my way around. I use a rubber mallet
to help get it around the tower. The big clamp sure makes it easy to get the last couple plug welds.

Jan 15 2017, 02:40 PM
All done and ready for the final trimming before the seams get welded!

I feel like I made some progress this weekend!
tygaboy
Jan 15 2017, 02:47 PM
Now I can get on with the bars.
Here's the final design on the cross bracing. I'll add a filler plate between them with some fun/interesting cut outs.
The final shot is proof that I have clearance and can fit the top with the arched upper bar!
I then laid the trunk on and everything clears. Woop, woop!
Now I'll fab up some brackets for those clips that hold the front of the top. I also need a bracket to locate the hood latch. This part of the car feels like it's finally coming together.
