I made some progress on the rear seat frame for my Bede BD-4C airplane today. The rear seat is a surprisingly comfortable sling. I cut the tube which is the cross bar. I clamped some wood onto the fuselage to hold the tube in position. Then I continued fabricating the angles which will be riveted to the fuselage.
Here is what I have so far. Click any photo to see it larger.
This last photo shows how the seat frame will work when the last two tubes are cut and welded in place. These last two tubes will go where the yellow lines are drawn on the photo.
