More on Fixing theHell Hole with Carbon FIber

It has been a long few months since I was seriously working on the Porsche. I am moving again soon and I need to get it in shape to drive again using the ICE before my next project. So it is back to cleaning our the rust and mixing epoxy resin and patching up rusted out pieces of the frame. It is starting to look good now and I am reasonable confident that it will be a strong long lasting solutions. There is not doubt about the relative strength of the carbon fiber versus the steel that has been rusted out. The only unknown is the relative strength and robustness of the bond between the resin and the steel. I have taken lot of precautions to throughly clean the metal as well as etching it so to maximize this bond. The underlying assumption is that with enough bonding surface the resulting repaired frame will last. Time will tell. Pictures tomorrow.

My other problem to solve is the emergency brake handle. IN the process of replacing the broken cable, I found that the threaded nut that holds the whole thing together to the car frame was rusted out. I found a replacement bolt and will try and replace the threaded material with a new nut held in by carbon fiber. We will see.
