[Land-speed] Fire Bottle Mounting Schemes

[neil at dbelltech.com]

Tom;

What kind of bolts & nuts were the ones that failed? Were these commercial
Grade 5 or Grade 8? Looking at the markings on the head of each bolt will
tell the story. 

Learning from data like this will be a help in the future to other racers.

Regards, Neil   Tucson, AZ

This is just for thought. I found that bolts securing many things on my car
did not stand up to what the car went through the crash. Three 5-pound
bottles were secured as a group by 4 - 1/4" bolts and the oil tank was
mounted with 4 - 5/16 bolts.  Both were striped from the car, shearing the
bolts and tearing loose from the fire bottle actuator cables and oil tank
steel braided hoses. I had Deist aluminum bottle brackets on the bottles
which survived fine, What is interesting is that the Nitrous bottles, which
are much heavier, stayed in place.

I have 4.0", 4.25",4.375",5.0" and 5.250" diameter clamps, black hard
coated with two, 25 dia. thru holes and two, drilled and tapped .25-20
thrd. What size bottles do you have???
You could use a flat plate, mount the bottles and brackets to it, then
mount the plate.
