Instrument Panel - 0.5 hours (482 Total)

The last thing I needed to do today was install my ferrite ring EMI filters to the Enigma. I was getting a significant amount of noise on my radio when the Enigma was turned on. I would need to set my squelch to the highest setting of 8 to block out the noise. With the Enigma turned off, I only need a squelch level of 3. After experimenting with several types of ferrite beads I was able to get the noise down to where I could set my squelch to 5 or 6.

In the photo below you can see the four of the five ferrite rings I installed. The round one in the center is hiding a fifth ring.

I then bolted the Enigma in place using some Locktite.

Door Lock - 1.5 hours (481.5 Total)

One of the extra features I was planning to add was a lock for my door. I had a local lock smith key a cabinet lock to match the same key I use for my Master switch.

The locksmith provided me with a thin steel plate that I was able to slip in between the Lexan and aluminum tube of the door. I pre-drilled holes in the plate that I later used to rivet to the door.

To get the lock as close to the edge of the door as possible, I needed to fabricate a bushing. Without the bushing I would have needed to leave clearance between the lock and the metal tube of the door to allow room for the nut to turn. I used some scrap aluminum tubing with an inside diameter of 3/4" as my bushing. Unfortunately, I wasn't able to get the lock close enough; the latch mechanism just barely overlaps the window frame tube. I'll need to get a longer latch from the lock smith.
