A lot of miscellaneous things today, but it sure took a long time to do them.
I tried fabricating the tunnel cover and messed it up. The drawings show the hole spacing on the cover plate, but don’t give dimensions for how the plate mounts on the stand-off Z channel. We assumed the edges line up because it seemed to fit. After transferring the holes to the Z channel the edge distance on the last hole was insufficient. The second stand-off came out all right since we figured out something was wrong on the first one. We’ll add some more Z channel to the list of stuff for ordering and re-make one stand-off later.
Next I tried to fix the seat-back brace. When Paul originally installed them he used a thinner piece of aluminum than was called for. We thought the seats braced against the aluminum strip in the middle of the cross brace. Instead, it’s supposed to rest against some aluminum L channel. I drilled out all the rivets and back-drilled all the holes that were already in the cross brace into the L channel pieces. The hardest part was setting the L channel high enough to allow the seat-back brace to slide under it, but everything worked alright after it was riveted in place.

While I was working on the side-projects, Paul spent the day on seat backs. They seem simple but there’s a lot of bracing and some hinges and that means a lot of holes to be drilled, deburred, and dimpled and there’s two of them. They’re almost ready for final riveting, just needs a little cleaning up and deburring and they’ll be good to go.
