Started work on brake and fuel vent lines. Found and test fit fuel vent line fittings. Found tubing cutter, tubing and bending tools. Studied drawings. Started test bends on 1/4" diameter, 0.032 wall thickness aluminum tubing. Additional time not included in reported hours: Discussed questions about cabin fuel and brake line kits with Tom at Aircraft Specialty Flightlines. Decided to try fabricating some of the tubing myself before purchasing manufactured assemblies. I still plan to buy some fabricated hoses, but not full kits. Found and started study of "Principles of Tube Line Fabrication" from Parker Hannifin Corporation.
