Having never done this before, I'm no expert, but I guess making the form will take at least as long as the finished piece. I'm 4 hours into the project right now. If it takes another 10-12 to get the buck right, that's no big deal.
The actual part will only be 3-5 pieces: two plates with attachment studs to be riveted on the back, the main cover, and maybe a bit of angle tucked in along the door edge to stiffen it up.
This sheet material wants to be formed, so I'm hoping once I get the buck just right it won't be too terrible a struggle to make the actual tonneau.
@Sacto Mitch teak is too expensive for me but as an TD replica owner I agree polished wood looks pretty cool on an old car.
