I began on the left wing frame. I'm using two of the metal sawhorses you find at Home Depot to build it on. I'm following the advice on the Homebuilt Help video, and doing it this way it does make it easy to flip it around and have access to everything. More of the same stuff, cleco, drillout to final size, disassemble, deburr, add corrosion protection, reassemble, rivet. I've got the skeleton riveted and am ready to begin skin installation. This work was done over 3 days, total of 7.5 hrs. I have 112.5 hrs. to date on the project.
