Brief Description: Seat bottom panel hinge drilling and seat back pre
I started the day by match drilling and then deburring the seat bottom hinges and panels. With that complete I turned to the seat backs. First the F-638B side angles and F-637C top and bottom angles had to be fabricated from stock angle. Then all the angles had to be match drilled to the F-637 seat back and deburred. This was followed by match drilling the bottom hinges and deburring those. Finally the seat back braces had to have four lightening hole cut in them, a hinge match drilled to it and then to the seat back followed by the deburring of everything. I still have to trim the seat back brace flanges and edge finish everthing but after eight hours I'll leave that for another day.
