So, we were on vacation for about 10 days and I have been out of touch. I am back at the model desk and am working on the rear seat for the fastback. The kit has a static back seat that does not move. Following along with A4garage I thought I would give it a try to see if I can make the seat move. It isn't perfect since there is a gap between the rear panel and the seat back, but it's relatively close and works.
This is the kit part for the seat back and the front hinged piece, all of which are affixed and won't move:
so, were the seat be able to fold, everything would rest on the rim going around the rear walls. The seat back is a little thick, and will be even thicker once I glue a backer to it. I am using .3" styrene sheet. Here is the seat back where I glued a strip of styrene to support the backer.
Since the seat back is higher than the rim once it is folded down I had to build it up. I used .5x.5mm styrene rod and built it up 2 stacks. I would have used .5x1mm but didn't realize it needed to be that high until after I had glued the first level on. I finally realized the curves in the back would be covered and never seen so I quit trying to curve the strips so carefully since it doesn't matter.
I glued a metal tube to the bottom of the seat back, drilled holes through the sides of the model, and used cut off straight pins to make a hinge. The way the seat is designed for the model I had to leave a space behind that section. The hinge "sort of" looks like the seat details which worked out well.
For the front fold-down piece I used angle styrene rod to reinforce the shape. I cut two pieces of .3" thick styrene sheet and glued to the angle rod to make the "L" shaped front fold-down. I cut a 5mm length of metal tube and glued into a routed out section at the back corners. I used the pins again and bent them 90* after putting them through the tube. I drilled a small hole into a routed section of the seat back to insert the bent pin.
Once in place, everything looks like it will work:
To cover the gap I had the idea of using tape as a sliding cover. I glued a piece of metal strip as weight to pull the cover back down flat when the seat was lowered. It looks crooked but I have since straightened it.
Of course there is a lot of clean-up, sanding, and painting to do, but it looks like I have a functioning rear seat.
