Having decided that the cockpit seats need replacing . I set about ripping the old ones out the reason for this was cracking either side of frame work .
Good thing I did as a large section wasn’t glued.. on both seats.
Having removed the 6mm 3x ply I am replacing with 9mm 7 ply Robbins elite This is much stiffer and will not add any significant weight as modern ply is quite light.
