Stored horizontal stabilizer. Dimpled vertical stabilizer spar bottom 22 holes per plans for RV-7 taildragger. Drill chuck for air drill from Brown Tools is defective, so I went to Lowes for a replacement. The replacement I got is a 3/8" keyless type and is quite large, and will probably be unsuitable for some tight spots so I will probably need to get another 1/4" key type chuck anyway. Need more primer for the VS parts.
