I didn't walk into it. I was hoping for it. Actually I have been a little concerned about that Canadian Blended Wiskey that I have been on for a while and hoping there was something better that I might be taking. I had been considering some Tennessee Wiskey called Jack Daniels, but now I see that I had better be looking at some good old Kentucky Bourbon.
Thank you Dr. Randy.

Some (many?) of you might be interested to know that I have made some signifigant progress on the blow oven to for the wheel well liners for the rear of the GTS and earlier cars. I have the oven nearly complete with insulation installed and ready to put the pressure chamber back in so I can start develioping the forms.
I have been giving some mental effort to the design of the forms, and will start tomorrow with measurements for the actual final design for the liners. I have Tony"s origianl GTS liners to work from and I have several S4 cars to work from. I also have the GTS wheel opening arch drawing that I received a long time ago to work with, so I think I can get the frinal design developed pretty easily.
I think I will be starting with the forms tomorrow and hope to have the inner form working shortly. I have a surgery scheduled in about a month, so that might hold me up a little, but it is on my knee, so not likely to be much of a delay.
The oven looks pretty good and I hope it is strong enough to hold the pressure, which is not actually that much; but 2 or so PSI is quite a bit of pressure when addeed up with several square inches of surface.
I'll report again tomorrow with what progress I have with the forms.

Gary Knox gets credit for the very useful drawings of the GTS wheel well openings that I am going to use for the final design, and for sending a bit of money to help in the development. The drawings were requested, but the money was not. Both are, however, very appreciated. Thanks, Gary. Jerry Feather

Jerry and Gary, Thank you so much for the efforts on these much needed ww liners. It is very important to make sure the dimensions on the drawing are correlated with the actual wheel well openings on a GTS and S$. I ordered up new GTS rear liners and they are different widths. The part numbers are wrong on one side so they end up being about an inch too narrow. Probably 91 S4/GT liners. Regardless, would really hate to have all of this effort done based upon incorrect data.

Hi Dan. Gary and I are on top of the differences in the wheel wells on the various cars. I think that the early cars through the GT 928s are the same and the GTS wells are different. The GTS wells are about one inch wider on each side and the wheel arch or opening is slightly different in shape. That is the benefit of the drawing that Gary send me some time ago.
What I plan to do is develop the inner half of the new liners so it is common for both the early cars and for the GTS cars. Then I am going to develop a form that will be adjustable so it can form liner halves for the outer part of the liners for the early cars through the Gt cars and then be changed to make the outer part of the liners for the GTS cars.
I understand the what people are getting when they order liners from the factory is a GTS liner for one side and a GT liner for the other side. That is a travesty; and I hope to solve that problem with these new liners so they will be suitable for both versions of the cars.
One consideration is that with the number of cars that have had their rear fenders "rolled" there may be some issue with trying to fit the new liners to those cars. I suppose that some adjustment or seperate form may be developed to accomodate that modification.
Other individual liners may also be necessary such as something that will accomodate the Storz rear fender modification. Time will tell.

Jerry you and Gary are on top of things. That is great. Some cars, like GT's came with rolled fenders from the factory. Others have rolled their own. Fenders too.

Dan, I understand the difference between the flanged fender opening of the early cars and the GTS cars. However, I think there is also a difference with the cars that have been modified with the baseball bat rolled fender modification which I suppose not only rolls the flange on the wheel well opening to a rolled edge, but also, I think flares the opening outward some to clear wider wheels and tires. It is not the change from a flange to a rolled edge that I am most concerned with, but the extra flaring of the opening that will cause some fit problems with the new liners.

Yesterday I did what I thought was the final wiring of the blow-oven and threw the switch to see it it worked. It blew the breaker, so I gave up until today before I burned something down. I am going out now and see if I can find the dead short. I think I have cut through one of the wires, so am going to have to wire it over again. I think it will take about two hours. Then, if it works, I am going to put the inner form on it with plastic in place and try to blow a prototype for the inner half of the liners. I need to get the inner half finalized before I can finalize the form for the outer halves. If I get something blown, I'll post a picture or three.

Jerry,
THANKS so much for your updates. I'll be looking forward to knowing the source of the short. Sometimes those are difficult to trace - as you know!!
Before finalizing the outer piece, you might want to get another fender drawing from a 2nd GTS - just to be sure. For anyone interested in supplying one to Jerry, I taped a piece of brown paper (as I recall) to the rear fender area around the opening, then traced the outline of the opening on the paper with a magic marker. Duplicate tracings wouldn't be a bad idea - in my opinion.
Cheers, and thanks again.

I think what I had previously figured out was the way to wire a 240 volt oven heating element is simply wrong, or I have them mounted to the oven incorrectly. I can't find a short in my wiring, but when I take it out and simply wire the switch to one of the heat elements it is still a dead short. Next I have to test the switch to see if something is wrong with it from the first try and then google some instructions about wiring.
My neighbor who was going to help me with this is gone for the weekend, I think.
I'll keep trying til I get if figured out.

Gary, I think your drawing is going to be just fine. I'm going to make one like if from my S4 and will be able to compare them with each other. If the difference(s) are what I think they ought to be we will be good to go. It really was a good idea for you to have put the line on your drawing where the rocker trim is located. I am going to use that line as the demarcation point between the GTS and earlier versions of the outer half of these liners. I think the plastic rocker and bumper trim is the same for these cars, so the difference in the GTS wheel opening is essentially from that line upward. It (GTS) has more flare by about an inch and it is a little rounder/taller also by about an inch, I think.
Tony, go to the beach. I'm going to stay at it more today, but you can catch up tonight.

We have a cook-out with friends later tomorrow so I will get some celebration in. In the meantime I am going to use some of this valuable time to progress.
