1936 Bugatti Atlantic Replica Project |
We're not this far along yet, but here's an image of a 57SC replica fabricated in the UK [Crailville Coachbuilders] that uses an ash wood frame for an aluminum body. Our master buck will start out looking somewhat reminiscent of this (but plywood, hardboard and foam, not ash). The buck model will likely be destroyed when pulling the molds, so quick and cheap are good. Pretty and durable are not required.The GIF below is of our starting point body views made from the basic 57SC dimensions, a chassis blueprint, and photos. If any visitors can provide any definitve body dimensional data, please contact me, Robert A. Booty:

[10-10-08] A start on the firewall/tunnel/floorboard modeling

[06-02-09] Floorboard modeling progress picking back up

[07-02-09] Floorboard modeling: fill-sand-fill-sand ad nauseam
(The bucket by the left rear will form a fuel filler neck passage.)

[07-13-09] Floorboard modeling - primer to seal wood & plaster, then a coat of gloss enamel

[08-31-09] Piecing / fitting glass cloth hand layup...
gelcoat, 1.5 oz. (per sq. ft.) mat, 4 general layers 10 oz. (per sq. yd.) E-glass cloth,
plus up to 7 extra layers cloth in high load areas (~0.019 in. thickness per layer)

[10-01-09] The finished 65 lb. fiberglass floorboard -- a big step here.
The stiffeners across the back are formed by 2 in. mailing tubes cut in half.
The access holes and covers are for the clutch slave and fuel tank hoses.
The handbrake lever (from a Jeep Grand Cherokee) washers and nut plates are epoxied in place.
The brake/clutch pedal mount is getting some bracket weldments to react pedal loads to the bottom of the firewall.

[10-27-09] Ha! The donor S10 belts & retractors look like they'll work out OK here.
The .125 in. steel doublers & nutplates are typical for the attachment hard points.
We're bonding them to the walls with a single part moisture curing polyurethane adhesive.
