Re: WIP: Tamiya 1/20 Tyrrell Yamaha 023

Some more fabrication work on the nose-cone.

According to the references in the Formula Perfect Manual, there are four raised studs where the nose-cone is mounted.


Source: Formula Perfect Manual Series, Vol. 6

Using bits of left over sprue, I fabricated 4 mount points so that the nose-cone can be mounted to the monocoque.



Moving on to the monocoque, I fabricated a new bulkhead to which the nose-cone would be mounted. This was made from 0.5 mm styrene sheet



I decided that I would remove the front suspension cover after all. This meant that I had to fabricate the interior and according to what I can see from the reference photos, it has a flat section in the middle with angled sections either side. In order to get the correct shape I had to insert additional slices of styrene to fill the gaps.



The barge-board supports have a section of the monocoque attached to them (the black pieces in the photo). I wanted to attach them now as they were just bolted on.



Turning my attention to the rear of the monocoque, I attached the rear bulkhead where the engine would attach. The kit piece includes the radiator assembly, so I removed them with a sharp knife. I cut out a section where the fuel cell connectors will be located as per my reference pictures. I also lowered the top section because I want to replicate the e-box shelf on the real car.



Finally, for this update but not for the monocoque fabrication task, I added a small piece of styrene to the engine induction scoop. On the reference photos the interior angle is level for the Brazilian GP (but not for the Argentinean GP).



Obviously there is much more work to be done. I just wanted to give you guys a taste for how ambitious I am being with this project.

Comments and critiques welcome,
Bill
