We've previously mentioned that we would be adding more door bars to our roll cage as we felt it wouldn't provide sufficient protection in a side impact. The current design only had a single bar running from the main hoop, connecting to the front section of the cage; meaning there wasn't a lot of protection anywhere above that - where our knees and legs would be...
So firstly we made a mockup of the bars using some plastic tubing of the same diameter. Cutting roughly where the notches needed to be before perfecting them onto a template - which we then transferred onto the actual CDS tubing.
First one completed with accurate notches cut out - ready to be welded in.
We made another bar identical to this using the same template.
Both bars welded in :up:
Would have been nice to continue the bar down back to the main hoop to make an X shape, but the gap between the body and main hoop is to tiny it'd be impossible to weld anywhere even near there :disrelieved:
Once that was done, I set about marking out where the final position of the fuel tank needed to be to allow room for fuel line fittings and a fuel pump. Also, bearing in mind where a firewall cover could fit over to meet MSA regs.
After taking some measurements, I marked up where the swirl pot needed to go and begun drilling away a 5" diameter circle in the boot floor.
The finished result... a perfect circle :smirk: Getting good at this stuff :wink:
Once that was cut, we made a cup to protect the swirl pot. I calculated that it needed to be 3.25" deep and have a circumference of just under 17". So I cut a piece of steel and bent it around a motorbike exhaust which was pretty much the perfect curvature. Then Alex finished it off using some of her jewellery making wizardry techniques to form it to the final shape.
We then cut a circle for the base - slightly larger than the diameter to allow for a weld around the edge.
The finished piece before Pete welded it together for us.
And there it is welded into the car...
Test fit of the fuel tank, now that it can actually sit flat and in the correct position finally!
Now what we need to do is:
- Cut filler off front of tank & re-weld onto RH side to allow use of original filler location.
- Buy a competition filler cap and fit it to the car.
- Weld in rear strip of boot floor.
- Modify seat rails to MSA spec.
After that I think the welding jobs are finished and we can then spray the rollcage, then the inside now its complete! :laughing:
