How is the trunk (turtle deck) floor fixed to the body - welded, riveted, screwed in place? I don't have the steel floor, it was replaced with wood many years ago. The body doesn't have any obvious marks where the trunk floor would have been attached. Maybe it was just squeezed between the body extension and the turtle deck?
My 27 roadster trunk floor is riveted to the turtle deck.
Little rivets all around the perimeter of the metal floor, into the sub rail.
Mine are as Dan said riveted to the subframe/ subrail with small steel rivets.Tim
My '27 turtle deck had the floor riveted to the sides like Bill described above. It all came off in one piece leaving just the bare frame and cross pieces.
This seems to be another difference between early and late 1926/27 production. It would be interesting to get some data points from cars with known serial # to learn when the change was made
My improved runabout body was bought in pieces, the main part seems to be early, while the turtle deck seems to be later style with the floor riveted to it. Another thing that seems to have changed is the placement of the four attaching screws to the seat back - no chance to attach the turtle without taking it apart and attaching each side separately - but then the gap for the lid was much too wide. Lots of adjustments was needed to make it fit
My car is September 1926 production.
The shipping and import duty for a USA made trunk floor will cost between 800 and 900 Dollars so I need to know if it is going to fit properly. A local body maker wants more than that to produce the piece to fit.
These two styles of floor are different, maybe because of the production differences mentioned above? One has a hump for the rear crossmember, the other does not. One forms a square corner at the front end, the other curves upward.
The rear body channel on my car forms an "L" shape as can be seen in the following images:
Eric, I see you saved the picture of the trunk floor I made for my old '27 roadster. The trunk floor really wasn't that hard to make. The only part I couldn't handle with simple sheet metal tools was the embossing. I was able to find a artist/blacksmith shop that let me use their Pullmax machine. The Pullmax is the only machine that can produce a embossed-like raised bead with a 36" throat capacity. Other than the embossing, all the other features were made in pieces and welded together. It did take a bit of time and a little head scratching, but it wasn't that bad to make in my garage.
Thanks for the details Kevin. Yes, I have been scouring the internet for anything related to the trunk floor. Did you need to make the "hump" for the rear cross member? I can't tell if the square area in the picture is that area or not.
