Silver Bullet construction proceeds through cobra roll

Posted Monday, August 30, 2004 9:17 AM | Contributed by xbombman

Vertical construction on Silver Bullet is coming along at Knott's Berry Farm. The cobra roll has been completed and track for the zero-g roll and turn-around has arrived. Photos on ACN.

Anyone notice the design change in the cobra roll's supports? The outter edge of the roll has two supports instead of one at the center, and one of those is supported from both sides with an upside-down "U." I suspect Raptor's support that keeps creeping off of its footer might have something to do with that.

Before anyone starts complaining about the exit section of the cobra roll having a brake installed, please remember that there is a chance it won't be used.

Brakes? Where did you see that?

Raptors support is creeping off its footers? How so?

Danimales - that piece of track with two holes through the spine. That's where the trim will be.

I wouldn't be too concerned about them putting a trim there. SFGAm's S:UF has a track piece very similar with two holes in it going into the entrance of the pretzel loop, but a trim was never added.

So far this coasters looking great, I love the look of that overbank turn before the Cobra Roll!

It only has the holes. There isn't actually a brake there (not yet anyway). I've seen a couple of other rides that have the holes without the brakes (S:UF), and still others that have the brakes but they aren't used (Dominator at GL).

It's a speed check. Talon has one; Dominator has one; lots of B&Ms have one. They're rarely used.

I'm sure that is because the pathway will going under the cobra roll like Medusa, you can see it on the rendering.

The path doesn't go under the U-shaped support. I can see having two supports to straddle the path, but trust me when I say that the force of the ride would otherwise put undesirable pressure on that footer. Raptor's support in the same place is a mess. Last time I looked they encased the base of the thing entirely in concrete.

Maybe earthquake safe construction requirements are getting tougher?

Wow, now that's what I call an overbanked turn! Makes MF's look wussy.

Does that look very wussy to you? Remember, the overbank turn on MF is close to 200 feet tall and the angle is not very wussy. Although I have to say the overbank on SB looks great!

Um, I know what it looks like. I also know what it feels like. And the one on Silver Bullet looks more like an inversion than an overbank.
