Just met my hourly goal for another week. It is too easy to find other important things to do early in the week and then work more hours late in the week to catch up. For some reason, the commitment to my grandkids to work a certain number of hours helps.

I researched socket head screws to use in place of AN4 bolts for contactor mounting. These will really improve future access and maintainability. Calculated lengths and added to aircraft spruce cart.

Also pulled out insulating boots and 2 AWG and 6 AWG terminals terminals purchased from B&C. Looked for additional sizes of insulating boots at Aircraft Spruce, Mouser and McMaster Carr. Added a sample set of boots to my Aircraft Spruce cart.

I finally decided to match drill the fuel feedthrough doubler to firewall and installed a temporary fitting.

After verifying the 1/2" EMT fitting was large enough for all the necessary wires and carefully checking obstructions, drilled a 0.75" hole in the firewall where Van's OP 30 wiring document specified. Used a file and step drill to enlarge the hole to approximately 0.8". Removed the screw on the fitting and filed the boss flush.

Drilled two holes for Adele Clamps to secure the top ends of the conduit that will run from the back of the instrument panel to the floor of the fuselage. Used OP 30 Detail D as the example.

Drilled four holes to mount the FlyLEDs strobe and position lights control PCB. Drilled an addition hole for a local ground and for an Adele clamp to secure wiring to the PCB. Installed the PCB using 4-4 1/4" standoffs, AN365-440 nuts and 4-40 stainless steel sems screws (built in washer) from McMaster.

Considered where to install the ANL mounting block and whether to use the one I have with the cover or buy a smaller one without a cover. Walked through options with Ellicia. One key issue how to install and remove the parts as needed. That ruled out most of the options. The use of socket head screws helps a lot and I will use those to mount the ANL block. I decided to use a wire and terminals to connect the ANL to the main bus instead of a bus bar. A bus bar made things a lot more complicated and isn't insulated. I need to look at other drawings and make sure I put the ANL in a reasonable place.
