Finished the mounting of the two defog fans to the upper fuselage. I dimpled the top skins for the doubler pates and attachment screws. Due to the reach for the dimpling, I had to use my decades only Avery C-frame tool. I worked like a charm. I saw the price for a similar C-frame from Cleaveland was well above $200. In '88 I think I paid $85. If I keep my tools long enough and with such appreciation, I should be able to sell them and fund my retirement! Then again, who in their right mind sells tools?
