Made canny progress today.
Started sticking the double sided tape down
Cut panels to go along the upstand of the inner wing.
Taped the horizontal surface up.
Marked up and cut out where the seat metalwork would bolt through. Decided to just bolt it through the carper and not try to compress the foam.
A bit of tape on the foam side panel.
Then I stuck the second layer on top. I went for two layers on the side as the original wadding insulation was thick there and there was only the carpet on the top originally.
Did the same on the other wing.
Marked out and cut four holes for the seat belt bolts.
Fitted the carpets in and bolted the seats and back rests down.
Cut two pieces of foam to fit the remaining floor space and taped it up with double sided tape/
Put the two pieces together and they fit perfectly in the back.
At this point I had to decide to either cut the floor carpet to fit under the side carpets or over them. I went for under to avoid a lump!
Just sewed the edging tape along the edge that lies against the centre bulkhead as it will be the only one showing.
You can't see the taped edge on the picture though.
I then fitted the support bars to get the full effect.
That's taken the best part of all day! However, I'm very pleased with the result. It looks brand new in there. I do need to paint the hardboard bases of the seats though! They've been stacked up and so I didn't notice.
