What's the most abundant component in a high power rocket? Is it fins? Airframe tubes? Coupler tubes? Rocket motors? The answer is centering rings, bulkhead plates, thrust plates — you can't build a rocket without rings!  Jerry O'Sullivan shares how he does rings right.

For anyone who migrates past the kit stage of hobby rocketry, inevitably the subject of cutting airframe tubing comes up.  There must be a million ways to go at cutting a tube, but do we ever find one that truly meets our criteria for what the ultimate rocketry airframe tubing cutter should be?

This article describes an unusual kit-bash, of a Vaughn Brothers BoB into a lightweight 29mm 2-stage rocket. The extra parts required are minimal and except for the necessary electronics the total cost of the conversion is very low. I added PML ‘chutes and AeroPack motor retainers because of their functionality and the very "professional" touch they add to the rocket.

We've all been there: the sun is blazing down, and we're standing in line to launch our rocket, only to discover we're assigned to fly from rack twelve, and they're currently on rack number three. Let's see... it's taking twenty minutes or so for each rack, and it's mid-afternoon already... To heck with this, I'll be back tomorrow!

The Tripoli Wisconsin Association's (TWA) launches have drawn more and more fliers from farther and farther away. This has been good and bad. The 'bad' can include long waits between flights due to the number of people flying. The question of how to solve the problem was asked.

Loki boosted darts were developed by the US Army, beginning in 1946. They were supposed to be an anti-aircraft weapon, but they weren't accurate enough to hit anything, and therefore, five years and many tax dollars later, the project was canceled. However, the Loki dart lived on as a research rocket capable of throwing small payloads (like radar reflective chaff) to impressive altitudes, 100-150K feet.

Many rocketeers are using altimeters for recovery system control. Some are also watching their rocket whistle down from apogee to go splat. What went wrong? The answer could be one or more of a number of possibilities. This article lists ways to prevent problems, describes possible failures and troubleshooting steps for when trouble pays a visit. Many of the recommendations also apply to accelerometer and timer recovery control systems.
