Called Randy at McFarlane Aviation and decided which style cables to use. Received cable OD information needed for firewall feedthrough selection. Updated notes on cables and saved in data sheet folders. Also downloaded and saved additional cable documents.

Called Doug at DoubleTee (firewallfittings.com) to ask for guidance on fitting selection. Doug promised to send me information on TTP-S and 7100 sizes.

Placed order for Cherry Max rivets and assorted screws. Deleted the firewall feedthroughs from the order since I don't know which ones I want yet and I can order direct from DoubleTee.

Centerpunched firewall penetration locations for "A" Throttle, "F" mixture, "L" alternate (bypass) air, and "M" nosegear bolt access. Drilled the M hole using a step drill and deburred it. An earlier drawing revision said to use a 1" hole for the nosegear bolt access. The most recent revision said to use a 3/4" hole. I used the smaller hole and marked it to remind me to test the hole size before finishing the engine mount installation.

Opened nylon 6"x6" packages from McMaster and thought about how to use them. Decided to mock up a few different designs using cardboard.

Thought about options to enlarge the center hole of the grommets from McMaster for the fuel line openings on the side of the fuselage. The standard size grommets won't work in the 1" holes specified by Van's. Ended up sandwiching each grommet between two boards and using a 0.5" step drill to enlarge the grommet ID.
