More work tonight!
Greg and Nate fitting the rear ring. "But it's supposed to fit!"
Perhaps the challenges with the rear ring explain this picture?
Applying glue to the joints. That's Titebond II, not epoxy....
A nice edge shot to show how everything fits together.

...it's starting to look kinda like a rocket!
The opened garage door behind gives a good comparison for scale.

Life is good! We just received our approval from the Tripoli BoD, so we're officially approved for a Q motor!
Now all we have to do is finish construction and get RSO signoff at LDRS, and we're golden.
I have more pictures to upload, including a couple from our display at the Offutt AFB Air Show. I'll post those in the upcoming days.

Fin laminations curing. It's always handy when the VAB has a convenient collection of rockets, bricks, jugs of water, and other equally heavy bits.
Upper section, starting to come together, prior to use of the hotwire.
Bob Brown, KLOUDBusters Prefect, dropped by to check it out. Here he is on the phone with Lance, telling him just how nuts we are. Bob didn't let us hear the entire conversation, but I think I did hear something about way, way, way, WAY away cells....
The Pershing II, close to completed, on display at the Offutt AFB Air Show today.

Now that is one awesome rocket  .
Why did you use wood for so much of it, would it not be better to use fibreglass or carbon fiber? Or would that become to expensive? |

A couple of reasons....
First, because it's a lot less expensive this way.
Second, to show folks that no, you don't need great gobs of carbon fiber and fiberglass to build a solid rocket. In reality, this one is horribly over-built, and there are no structural composites in it anywhere.

I had the chance to see the Pershing II when I was out at the Offutt air show on Saturday. Looks like Kevin and company have a fair amount of finishing between now and the middle of next week, but I'm pretty sure that when it flies in two weeks, it will be turning some heads.

For those wondering why parts are black, that's because it's some paint we had around from the Redstone. We used it as a primer, to help de-fuzz the big tube.
Last night, everything got a white primer coat. It's currently baking in the Nebraska sun. We'll be putting olive drab latex house paint over that, then Lisa will do detail work with an airbrush.
As you can see from the pics from the Air Show, the rocket is basically done. Tasks remaining are:
Bevel leading edge and root tip on fins
Install cable for upper recovery
Add nose weight
PAINT!

Rumor has it the rocket is done, except for the paint.
Paint happens tomorrow -- a lovely shade of olive drab.

Like Apolloleader, I was able to see the P2 rocket this time at LDRS27 and I took some pictures and video.
I also was honored to have a tiny part in the project in that I painted the USARMY letters on the side of the rocket! The final flight of the rocket was absolutely awsome! I am new to Rocketry and for me seeing something of this scale was very inspiring and it was the highlight of my vacation to be able to attend LDRS27 and to see the Pershing II Fly! I would like to thank Troj and the team for letting me add a little something to their project.
Additional pictures can be found on the Tripoli Rockets Magazine website
in the photos section under ldrs27 day 5. http://www.rocketsmagazine.com
Keep in mind this rocket is a scale model of the real Pershing II and is classified as experimental. This area of high powered rocketry is what expands the technology and grows the hobby. Issues during flight provides data to improve future flights.
Here is a video of the flight!

As you can see from the video there was an issue and the landing was hard. Troj can speak to the technical aspects but for me and the many others at LDRS27 this was an amazing rocket. Thanks Guys for bringing this to LDRS and best wishes for future projects!

I am really curious what happened there. I remember seeing a gorgeous lift off and then parts started coming down. It's too bad. That was a work of art.

We have a theory, but until we get some of the last data, we're holding back on public statements on it. Our initial theory at the field has proven to be inaccurate.
