Since I haven&#8217;t painted yet, I could to that but so far I&#8217;ve been deferring that decision.<\/p>\n<p>But I do have one place on the lower cowl that I have to deal with. When the hole were being drilled in the lower cowling, one of them ended up being directly under the electric fuel boost pump.\u00a0 There&#8217;s not enough room for a regular nutplate.\u00a0 Even a a low profile tinnerman would probably not fit.<\/p>\n<p>So I decided to do a captive flange under the fuel pump. FIrst I made a spacer with a couple layers of triax and BID.\u00a0 This has to be the same thickness as the cowl flange. Then I cut a piece of leftover titanium that would extend aft from the firewall past the fuselage flange by about a half inch. Next I drilled four holes through the fuselage, spacer and titanium. Finally I put a film of structural adhesive between all the parts and riveted them in place.<\/p>\n<p><a href=\"https:\/\/www.velocity-xl.com\/blog\/wp-content\/uploads\/2016\/06\/IMG_20160604_135826562.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-3542\" src=\"https:\/\/www.velocity-xl.com\/blog\/wp-content\/uploads\/2016\/06\/IMG_20160604_135826562-150x150.jpg\" alt=\"IMG_20160604_135826562\" width=\"150\" height=\"150\" \/><\/a> <a href=\"https:\/\/www.velocity-xl.com\/blog\/wp-content\/uploads\/2016\/06\/IMG_20160604_135835483.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-thumbnail wp-image-3543\" src=\"https:\/\/www.velocity-xl.com\/blog\/wp-content\/uploads\/2016\/06\/IMG_20160604_135835483-150x150.jpg\" alt=\"IMG_20160604_135835483\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<p>Filling the countersunk rivets will be done during paint prep in the fall.<\/p>\n<p>If I like how this works, I may do this all around the fuselage\/cowling attach area.
