Today I went to the RV construction department of Walmart and purchased four plastic grass door mats ($3.89 ea.) for use as padding of the construction table once I take the wings down from the jig. I also bought some padding for the wing cradle. Tonight I began working on the aileron brackets. They are already cut to shape and drilled to final size, so all they needed was finishing and priming. This took longer than one would imagine. I had to sand and polish the rough edges, deburr the holes and then countersink certain of the holes, as per the plans. Then, I primed all of the parts and clecoed them back together. I will not rivet them tonight because it is too late.
