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 be 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.
