I've been doing some metal work the past few days and now have my fire bottles and fuel cell in place. They will have to be re-installed many times before the car is actually finished, of course.
Here is the mounting bracket for a 10 lb automatic extinguisher (it goes off like an overhead sprinkler system-- it senses heat) and a manually-actuated 5 lb Fire Bottle. Both are Halon type extinguishers. I bought the machined aluminum mount on eBay; it is ex-NASCAR and so is the white 10 lb bottle. It will be mounted in the left side pod, riveted in place under the stressed panel, ahead of the dry sump oil tank.
The 10 gallon Fuel Safe fuel cell is mounted in the right side pod; in the rear of that pod is another manually-actuated 10 lb Fire Bottle. I'd like to have the stressed panels anodized but they are 0.063" 7075-T6 which does not color anodize well. I'll probably just finish them with a fine grit orbital sander, clean & prep, and paint them with a zinc chromate primer. They won't be riveted in place until the chassis is finish welded, sandblasted, cleaned & prepped, and painted.
