Guys,

I have a 10L43A chassis for a Continental that was missing the heat barrier between the HOT and Damper tubes and the HV cage. So I decided to make a copy of the one on the other 10L43A chassis that I have.

For the heat blanket I went to the local Summit Racing store and picked up some Thermo-Tec #13500 heat barrier. It is 12 x 12 and .041 thick. It is good up to 2000 degrees and it has a sticky back. I can get 4 heat barriers from this piece.

I used my CAD program to draw it out and saved it to a .pdf file which is attached to this post.

I used some 3M 77 spray and lightly glued the pattern to the foil side. Then i peeled off the backing and stuck it on some thin (.008) tin that I use to make model airplane fuel tanks from. Then I used some scissors to cut it out. I used a 1 inch Forstner bit to drill out the hole for the HV lead to the HOT.

I then used some 3/8 wide Kapton tape to line the edges to eliminate any fraying of the heat blanket. I bent it along the dotted lines using my steel ruler and the edge of the workbench.

Turned out real nice.

Crist, Thanks for making this available. Excellent job as always. I'm going to fabricate one for my Continental. I'm not even sure there was one there originally. With the Chassis standing vertically the heat against the Hv cage would be a lot higher than the regular Predictas with the chassis laying flat.
