Got to use the magic tool again today (shrinking disk). The section I was working had some mild oil-canning.

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.

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.

That provides a uniform matte black coat. The surface looks pretty good.

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.

I also got started on the right rear fender, laying out guidelines to compare profiles.

Here are the some lines on the left side to use as profile models.

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.

Of course, that means re-grinding, re-shaping, and re-smoothing.

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.

Step 2: press against the fender, holding the gauge perpendicular and along the selected line.

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.

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.

After about an hour, I got the right fender profiles pretty close to the left side.

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.
