Build


Complete the Chassis

Step 01

The Bulkhead Support Strut Flange slots into the Bulkhead Support Bracket, as shown:

Secure these together from underneath with one (1) EP screw:

Step 02

This Bulkhead Support assembly fits to the top of the Bulkhead Frame.

There are two keys on the post that match up to the hole at the top of the Bulkhead Frame. Pay attention to the orientation:

Secure this into place with one (1) HP screw:

Step 03

The Bulkhead Frame assembly fits on top of the main chassis frame, behind the engine, leaning towards the back of the car:

Secure both sides of the Bulkhead Frame to the Tubular Frames with two (2) CM screws.

This is your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Turn the entire chassis over and secure the bottom of the Bulkhead Frame to the main chassis with two (2) FM screws.

These did not line up very well at all. I had to push the left and right sides of the car together to align the holes correctly:

Step 04

The Bulkhead Support Strut connects the Bulkhead Frame to the right lower front of the main chassis. The flattened end should be at the front of the engine. Feed the rear of the strut under the exhaust manifold, over the high pressure oil line, and under the hole in the Bulkhead Frame, as shown:

Secure the rear of the Bulkhead Support Strut to the Bulkhead Frame with one (1) CM screw:

Secure the front of the Bulkhead Support Strut to the Main Chassis with one (1) CM screw:

Here is another angle of the strut installed:

Step 05

Turn the entire chassis upside down and look at the rear of the car to see how the Rear Frame fits:

Place the Rear Frame into the Main Chassis so all four holes line up correctly:

Secure the long crossmember to the chassis with (2) EM screws. Secure the short crossmember to the chassis with two (2) FM screws:

Thoughts


With this phase complete, the main tubular chassis is now finished! Its looking really good so far. Unfortunately, most of it will be hidden once the model is done. The two frame pieces are metal, but the bracket and flange are plastic.

Running Total of screws used so far: 111
