makes several potting compounds that would be of interest for your
application. There are dozens, so you can pick and choose the
characteristics that are most important to you.

engine monitoring 4P
Dear
subscribers,
I got tiered of looking at how all
the wires run through my bulkheads (picture 186). There were even some gaps
and I questioned that this would seal very well.
Since I was too cheap to buy the
300$ sealed bulkhead connectors I decided to make my own (picture 202, 203). I
made a sleeve out of aluminum counted the wires and drilled a hole for each
wire/cable with the right size. I was planning to fill the back side of my
bushing with approx ¼’’ of flox to make the plug air tight. I was planning to
make the flox really thin that it would flow in nicely and would seal good
around my wires. I am concerned now that the flox might not b
e flexible enough
once it is cured. Are you aware of any sealer that I could use that is really
thin in the beginning and that would flow in
nicely?
I also found a lot of wires to the
engine monitoring system (picture 200) being extended in the engine
compartment. Is this an area of concern? I was thinking of buying new sensors
with longer cables and run them to the computer box in one
piece.
What is proper for heat protection
for the cables in the engine compartment. I found products that last to 500
degrees F. Some silicone/fiberglass combinations run up to 700 degrees. Can I
go with the 500 degree products?
I do not have any documentation on
my engine monitoring system and I don’t find anything on the internet. Can
anyone give me a file/ copies for the wires installation sketches and set up
instructions?
I got also done with my brakes now
(picture 195). I used aluminum hard pipe since it is a very similar
application which is used in our Cessna. I also used plasma nitride for rust
protection on the rotors and drilled them to get more
surface.
