That's basically what I did. I have four aluminum strips, approx 1 1/2 inches wide, one under each "cheek of my butt", that were preformed to the shape of the seat and have the downturned flange over the spars. The seat back is hinged to these strips using similar strips of aluminum. 1/4" foam was glassed on one side and attached to the strips with the glass side down. The top side was then glassed. My seat back hinges forward and the entire assembly can be removed as a unit. It is held in place with 3/16" bolts, one through each turneddowned flange and the spar cap. After the seat was glassed I added some 1/2" foam strips to the back sides of the strips, contoured and glassed for additional stiffness. The seat has held up well except for the back where I apparently applied a bit too much pressure at some point sliding down in to the seat. Just a slight crack in the glass. I'd hate to repair and repaint now that I have the autograph of Paul P., EAA #1 on the back side. I think I built a simple jig from some scrap pine so I could work on the seat outside the KR.
