| Subject: | Re: Firewall pass through |
I am changing my batteries from in front of the firewall to behind the seat.
The existing firewall pass through bolts are 1/4" . Will this still be
sufficient for bringing power from inside back to the engine compartment?

Go ahead and put a terminal onto a 4AWG wire
and see what it looks like. I might have you send
me the installed terminal and I'll slice it open
for microscopic examination. How many die sets
come with the tool?

Jim,
Are the =BC bolts built into a firewall device designed specifically for pa
ssing cables through? If so, does it have a rating? I've seen similar in th
e racing world where they bolt the connection through. These work perfectly
fine so long as you have the correct device intended for the job.
The below uses a 3/8 bolt, but there are many variations on this product. I
f you go this route be sure to protect the exposed bolt from contact with o
ther gremlins. Some come with covers.

Thanks Ken,
I've a couple in the electronics box from when I made some dimmed map
lights. I'll give that a try.

Emacs!
Fire wall feed-thru products like this are electrically
adequate and VERY convenient. Just be aware that plastic
insulators would not pass muster in the TC aircraft
world with respect to maintaining fire wall integrity.
Admittedly, fuel fed fires under the cowl are VERY
rare events . . . and we know that those-who-know-more-
about-airplanes-than-we-do are fond of writing rules
for mitigating the rarest of risks.
A lighter, less elegant but time honored and much tested
approach is to bring unbroken wires through the fire wall
protected by shielded grommets and sealed with a fillet
of fire-putty on the engine side.
It's your airplane . . . your call.

Yeah, went to the website and looked it up.
That's a pretty good range. Too bad they
didn't make those hex shaped holes tailored
more closely to the real-world of terminals.
But then, we have no knowledge of what the
designers were handed for design goals . . .
nor the market demands that drove the decision
to fabricate the tool.
I'll be interested in seeing what your test
crimps look like.

FYI
T&B has a rental program for tools like this. Might be a better choice than
using a universal crimper.

If it is quiet I can look up the resistor values that I used to adjust
the voltages to something more suitable. I think full dim for my EL
inverter cube was around 5 or 6 volts so I altered the design a bit to
still have full range adjustment on the knob.

I think I used to hear numbers for gross weight on the B-52H
models as topping out near 500K pounds. Here's a rejected take
off test on the 747-8 loaded to nearly a million pounds. This
is what you call "really hot stuff" . . . no pun intended.
