Firehawk's N2 racecar project

[firehawk]

While the car was getting the rollcage built in, I had to invent something to do with the parts I had at the garage. To test the blasting cabinet we bought, I pulled all the cooling system bits from the engine and cleaned them up by blasting them with a really fine glass bead.



Even old dirty and oxidised aluminium parts came out shiny and smooth - what a brilliant tool! I took the old 13" wheels next and blasted the rim halves clean, and then switched to regular sand to clean the red paint off the centers. I gave the old centers a few layers of gold paint a clearcoat.



Once the old centers had dried, I assembled them together with the new 4.5" outer rims and old 4.0" inners to produce a pair of 9JJx13" wheels for the rear axle.



Then today, I went to pick up the car from the workshop and brought it back to my garage. Several rally drivers recommended this guy and I can see why - he's pretty good at welding.





The diagonal support for the main bar is braced both against the driveshaft tunnel and the 4-link housings. The front strut turrents are also braced to the rollcage with two staggered tubes for additional stiffness.





Some extra details.











Next up is modifying the driver side floor for the pedalbox and the seat, as well as making the mounting points for the steering shaft once the seat position is finalized.
