There is no Meet n Greet here, so I'm just saying Hello to everyone.
I really hope this place takes off.
As this place grows, I hope to get into Cert. 1, dual deploy and learn what the heck cable cutters are and how they work.
I'm venturing from, "Over There" (Woody's Workshop)  to see what happens here.
Hope it works out.
I've been on n off again since the late 60's.
Haven't flown anything past an Estes D so far, but have a bunch of kits in the build pile that will take me way beyond that.
BTW, Estes is having a sale right now. Wish I had the funds to make a few more purchases.
Don't belong to NRA or anything else. Always have launched in my life long friends farm fields.
Guess that will have to change just to get engines in the future.
But until then, I just keep building.
Until the SSDI finally arrives and can actually afford to launch and join NRA.
Which is confusing to me. NRA National Rifle Association?
Or is it NAR? I can never remember which is which. Good for a laugh now again though!
I think they go hand in hand cause you shooting something into the air.
Anyways, Greetings all.

Sorry...  I'm a little confused...  I want to be 100%...  Over "there" you're Woody's Workshop... Right?

FWIW...
NRA stands for the National Rifle Association, whereas, NAR is the National Association of Rocketry.

Welcome!  Just be aware, there's a lot of people who don't like off topic (non-rocketry) stuff here.  Then again, there's not a lot of people here... yet.

Pointy Side Up!

Launching is Optional... Landing? That Depends on Trees.

Guys, I moved the thread over here, which is a more appropriate location.
We'll talk about establishing a welcome/introductory section, as soon as we get a moment.
It's just been crazy busy of late...

Welcome aboard, Woody.  Glad to see you posting here.  The user interface is pretty clean and simple so no issues with your browser running amok.

I have both an NRA and a NAR sticker side by side on the bumper of my truck. It's always a conversation starter at either range.

Well, that's interesting.  I seem to be replying to everyone in the thread and clicking on the minus quote doesn't eliminate the extra quoted posts...curious.

Kit, go to the bottom of your screen and select new reply, instead of selecting quote at the bottom of the post.
That will eliminate all of the replying to everyone issue.

I can explain cable cutters. A cable cutter is a small, hollow, metallic chamber with one closed end, one open end, and aligned holes on opposing sides.

Inside the chamber goes a little piston. You insert an igniter, that is connected to a DD altimeter, and shove it and some BP into the chamber. You have a threaded closure at the open end that the igniter goes through.

A standard cable-tie goes through the opposing holes, and wraps around your chute/Nomex burrito. The chute cannot open until the cable-tie is cut.

You can use motor ejection to eject the nose cone and pull out the chute burrito; but the chute can't open because it is wrapped by the cable-tie. This unopened chute acts like a drogue, and the rocket free falls until the DD altimeter detects your mains altitude.

The ejection charge fires. The BP in the chamber ignites and explodes, shoving the piston into the cable-tie, and cutting the cable-tie. The chute now opens and the rocket floats down the remaining distance under main chute.

You also have a little piece of Kevlar thread to hold the cable cutter to the rocket after it lets go of the chute.

The whole point is to simulate DD with a single chute. And if you use motor ejection, it eliminates the need for charge wells and tons of BP. About 0.1 grams is all it takes. You still need to customize the rocket to hold an altimeter bay, but if you put it in the NC, then you don't need a coupler and don't need to extend your rocket.
