And this.

I propped the trunk lid in place, to compare alignments. The lid has its own issues, including a dip along the trailing edge.
bkrantz
Apr 25 2020, 08:28 PM
Right side looks pretty good.
bkrantz
Apr 25 2020, 08:29 PM
Left side not so great. The problem is mostly a "droopy" lid edge.
bkrantz
Apr 26 2020, 08:58 PM
I worked more today to get things "straight": the top and bottom of the raised boss, and the top edge of the rear panel.
After some moderate metal work, things looked a little better.
bkrantz
Apr 26 2020, 08:59 PM
Eye-balling along the lower edge of the boss. Ignore all the lumps for now.
bkrantz
Apr 26 2020, 09:00 PM
Watching the angles.
bkrantz
Apr 26 2020, 09:02 PM
When things where looking nearly straight by eye, I rigged up my long level as a reference line. Looking pretty good, with a variance of about 1/16 inch.
bkrantz
Apr 26 2020, 09:04 PM
But the trunk lid has its own problems, especially along the rear edge.
bkrantz
Apr 26 2020, 09:06 PM
As I started to work the trunk lid edge, I heard a crunch, and my rust-free lid suddenly had a rust-trough hole. Damn. (See my other thread asking for advice)
bkrantz
Apr 26 2020, 09:07 PM
Anyway, I kept working the lid edge and got things a bit better before quitting.
bkrantz
Apr 26 2020, 09:08 PM
Looks good enough for a 10 foot car, but I want better.

Great pic here Bob.
Well...spend a bit more time tweaking the trailing edge of your rear "bonnet" and I think you'll be very satisfied with the result.

Yep, I consider bodywork the next phase, or two. First, I want to work the metal to get it as good as I can, and then later need only some thin filler.

I decided to take a break from the rear, and work on the front left fender. To get enough flex in the outer curve next to the turn signal hole, I had to cut slots in the flange. Once I got the profile correct, I welded the flange. Things got rigid again and held the correct curve.
bkrantz
Apr 27 2020, 08:24 PM
Next, I welded all the puller holes from the PO repair. And, I committed to my first mod: shaving off the warts, and filled those holes as well.
Sorry, I should have told purists to look away.

Dude. I've discovered I'm much more of a purist than I thought, but even I couldn't bear to put those ugly warts back on my car. It looks so much nicer without them.
Watching your work is really awe inspiring. I know you said this isn't your first rodeo, but just how many rodeos have you had? Watching your work is inspiring and - a little annoying.

After grinding the welds, I got the fender shape about 90% right.
bkrantz
Apr 28 2020, 08:16 PM
To get the next 5% I am going beyond where I stopped in the past (and where I would use thicker filler to get the final profile).
So I am trying to learn new tools and techniques. Like using a template gauge, and taking profiles from an unmolested fender to guide my work on the victim fender.
bkrantz
Apr 28 2020, 08:17 PM
Take the curve from here...
bkrantz
Apr 28 2020, 08:18 PM
And use it to judge the work here. Gaps still need work.
bkrantz
Apr 28 2020, 08:19 PM
Getting closer to 95%.
bkrantz
Apr 28 2020, 08:20 PM
And after some additional work by eye and feel. I have another new technique to try for even more refinement.
bkrantz
Apr 28 2020, 08:21 PM
But meanwhile, plugging the wart holes on the right side.
bkrantz
Apr 28 2020, 08:22 PM
This fender also needs some shaping, especially along the front and lower corner.
bkrantz
Apr 28 2020, 08:23 PM
Working through the welding list.
bkrantz
Apr 28 2020, 08:24 PM
And getting started on the shaping list.

I only had about 30 minutes in the garage today. I spend most of the day listening to and grading student presentations (senior thesis projects), and then did a stint of yard work to keep the boss happy.
I did have time to mark reference lines on the right front fender, check the profiles, and do a bit of banging.
bkrantz
Apr 30 2020, 08:22 PM
Got to use the magic tool again today (shrinking disk). The section I was working had some mild oil-canning.
bkrantz
Apr 30 2020, 08:22 PM
Then I got on to shaping, and things are close to matching profiles.

Just dropping in to admire your progress. You have some serious metalworking skills and a ton of patience. Can't wait to watch your car continue to come together.
bkrantz

Thanks--just learning as I go. My secret weapon is that I don'r know enough to doubt my chances for success.

On the the next phase, trying to get the fender as smooth as possible. I might have fantasies about getting the metal ready for paint, but I can settle for a surface as smooth as possible, and then a minimum amount of filler.
First step is using some guide coat spray.
bkrantz
May 1 2020, 08:55 PM
That provides a uniform matte black coat. The surface looks pretty good.
bkrantz
May 1 2020, 08:57 PM
Then a a light sanding, to reveal the highs and lows--things look a little rougher now!
Now to raise the low spots and tap down or grind the highs.
bkrantz
May 1 2020, 08:59 PM
I also got started on the right rear fender, laying out guidelines to compare profiles.
bkrantz
May 1 2020, 09:00 PM
Here are the some lines on the left side to use as profile models.
bkrantz
May 2 2020, 09:09 PM
Had a fun visit by a local 914 friend today, who brought his raspberry 6. We had fun talking 914 and other car stuff, and I was able to get a look at some details that will help me. Thanks, Mike!
I then got back to work, but found that my grinding broke though some of the puller hole welds, so I took a few steps back, and re-welded.
bkrantz
May 2 2020, 09:11 PM
Of course, that means re-grinding, re-shaping, and re-smoothing.

May 3 2020, 06:27 AM
If it's not too much trouble at some point can you explain how you are using the index / guide lines on the fender? I get it conceptually, but this looks interesting and potentially helpful. And I need to get better at this...
Thanks.

Anytime Bob - it was nice to get out and see your work first hand.

Just for you, Rob, I took some photos of my procedure with the template gauge.
Step 1: "zero" the gauge by pressing against something flat.
bkrantz
May 4 2020, 08:19 PM
Step 2: press against the fender, holding the gauge perpendicular and along the selected line.
bkrantz
May 4 2020, 08:21 PM
Step 3: Now hold the gauge (gently) along the same line on the other side, and note the misfit. Areas to be raised or lowered are obvious.
bkrantz
May 4 2020, 08:22 PM
Step 4: repeat the process along all the lines. I start with the central vertical line, then the central horizontal line, and after that work my way out.
bkrantz
May 4 2020, 08:23 PM
After about an hour, I got the right fender profiles pretty close to the left side.
bkrantz
May 4 2020, 08:25 PM
I then went back to the front fenders, trying to level out the high spots, followed by another guide coat and sanding. I might be getting as close as I can without going nuts.
Here's the left side.
bkrantz
May 4 2020, 08:25 PM
And the right side.
