Yep, you nailed it Robert
Just could not leave it that way. You might agree when you see the pics.
Here is a top view of Pete's pants and a side view of the replica in the museum.
Now Wendell's cross section I think is a little wider proportionately than Pete's pant. I am going to stick with Wendell's cross section witch will preclude getting Pete's shape on the money. But the shape I had was far to blunt. Also if you look at the replica, that hub cap has a distinct turn in toward the front. My pant flattened out far to soon. The first pic below is the pant before alteration. It looks a little torpedic. The one next to it is after adjusting the plan view.
The difference is settle but distinct. As I am looking at it I might also tapper the tail sooner. Will ponder it
It is far easier to cut the plan view when all the edges are square. So after pondering it for a while I came up with a plan.
I cut a new profile out of 1/4 inch mdf. Then centered each spat over it and shimmed the spat so the datum line was level.
Then used the disc sander and a bright light to sand spat to new profile. Once the spat got ground down close to the template size I penciled the edge of the template and sanded the spat until the pencil was brushed off.
With the template it was easy to get them both symmetrical.
Once all the edge get feathered into each other It will look much better.
But not tonight.
Please opine if the shape looks amiss. Every time I look at it I get different conclusion.
