Dec 3, 2010 update to the Lincoln Mark VII project car

Fitting Feet

Another evening, another Lincoln work session.
First, a meeting of the minds: How do we make the seat adjustable?
It's also time to start fitting the cage--for real. But first, we need to grind away paint and undercoating so we can weld the cage to the car.
We also want to fabricate some larger feet for the cage legs.
And some progress. Our bigger feet should give the cage an even better foundation by reinforcing the floor.
Our ATL fuel cell has arrived. We probably need a better mounting arrangement.

This is definitely not a bolt-together project.

Tonight’s project dealt with an important question: How do we mount the seat and deal with the different driver sizes? The answer: We’re going to need seat sliders of some kind.

We also removed the brakes so we can get a core charge—the rears appear to be worth $77 each. Who knows what horrors our brakes have seen, so we figured it’s best (and safest) to start with fresh calipers from the local auto parts store.

Cage welding also has started—well, specifically, attaching the cage feet has started. We want to add beefier plates, and by the end of the evening two were in.

The main roll cage hoop looks a bit narrow, though. That’s not surprising, as it was designed for a car with an interior, and ours is gutted. Maybe we can bias it slightly toward the driver’s side of the car. This is definitely not a bolt-together project.

I don't mean to sound like a jerk, but those welds in that picture don't look up to par for those feet. I'm sure it looks fine but if a collision occurs the shearing forces will rip those welds apart.

Are you using any shielding gases?

I don't see any well defined bead and that lends me to believe that proper penetration was not consistently achieved throughout the entire weld. Think of it like this, without a well defined bead your weld becomes more like perforated paper. Sure, in one instance its strong but apply shearing force and it'll rip right apart.

The welds look much better now. Stay tuned for additional updates!

Good to hear, just making sure the people producing my favorite magazine are around for a long time!
