| | [ Not displaying correctly? View web version. ] | Apogee Rocketry Workshop #358: | | Are you confused by all the different choices you have in epoxy? At Apogee Components, we currently carry five different varieties. What makes them different? Which one is best? Which one should you get? They are all strong, so that really isn't the determining factor when selecting an epoxy. The choice really depends on what you're trying to accomplish. In this video, we'll look at the two variables that I use when selecting which epoxy adhesive to use. Then we'll go through each of the five types of epoxy we have, and give examples of which situations and conditions where you'd probably use them. You'll come away with a simple way to choose the right epoxy for your next rocketry build.

| Check out the latest products to hit Apogee's shelves! | 15-Min Cure Time Epoxy | |
The Mid-Cure 15-min Epoxy from Bob Smith Industries, is a really nice epoxy for general purpose use. It cures reasonably fast, hardens very clear, and is quite strong. The extra setting time (verses the typical 5 minute epoxies) allows time for air bubbles formed from mixing to come out of the epoxy before it sets up and allows some additional time when you are doing a more complicated joint or gluing job. Comes in a convenient 4.5 oz bottles that allow you to mix a little, or a lot. |

| RockSim v10.4.0 Beta | |
We made several changes to the RockSim software, and are announcing this beta version for all current users to try out. There are a few new features, as well as more than a dozen fixes to issues that users have reported. This will be a free upgrade for all v10 (or version 9) users. But we're calling it a "beta" to indicate we're still open to fixing an new issues you might discover. More information and download links are available here. |
| Aerotech G8ST-P | |
The Aerotech G8 motor, with a 19.8 second burn time, is designed specifically for those advanced rocketeers that want to try gimbled (thrust-vector control) of their rockets. It has such a low thrust that relying on fins to stabilize the rocket is not something that we'd recommend. It also does not have a delay or ejection charge for recovery, so you'll need other electronics onboard to deploy a parachute. Check it out here. |
| Fresh Super Glue | |
We've got what is commonly called 'super-glue', Cynoacrylate, or CA adhesive. It is a fast way to glue parts together. We use it almost everywhere in rocketry. It can bond woods, paper, fiberglass, metals, and some plastics. Produced by Bob Smith Industries, this is guaranteed fresh for 2 years. There are 4 different types available, plus debonder and accelerator. Check all the options out here. |
| Make Carbon Fiber Tubes | |
Here is an extensive and detailed video course on how to make Ultra-Lightweight Carbon-Fiber Rocket Tubes. They're so light, they give you an unfair advantage in competition. These are the ones that my daughters, Allison and Ashley used in Romania last September at the 2021 World SpaceModeling Championships. Allison was part of the senior Silver Medal winning USA team, and Ashley took home the Bronze Medal in the Jr. Division. The girls were taught how to make their own tubes, so if they can do it, so can you. The training course consists of 5 hours and 42 minutes of video instruction, covering everything I know about how to make a successful tube with a glass-finish using a 2-piece mold. It even includes all the secret techniques and materials, and where to buy them, including where to get the 2-part mold. This course is on the Udemy website, not at Apogee Components. |

Mis-matched Cluster Motors What would happen if you didn't have all the same motors in a cluster? In this week's launch, I took the Klima Andromeda kit, and put three C6-7 motors and a single B6-6 motor into the 4-engine cluster mount. What difference does it make if all the motors aren't the same? Check out the simulation, and see what happens. Then as a comparison, fly the rocket when all the motors are identical. | |

“Tim, I want to thank you and your staff on terrific service that you all provided me last week. I live near Tampa Florida, I was preparing my two stage Nike-Apache electronics bays when I discovered that I did not have any stand offs for the altimeters and timers. That was on Thursday afternoon 4:30pm local time. So I went online to to your website and found the items that I needed, including a bulkhead. I placed that order thinking that the parts would arrive after the weekend. Incredibly I received the parts on Saturday in JUST 2days ! That gave me more time to prep that rocket and one more for our Tampa Tripoli Rocketry Association launch. I can’t thank you, and your staff enough. Also I would like to add, that I have visited your store on three separate occasions to purchase some items directly, when I visit Colorado, and each time I am greeted with warm smiles and enthusiastic people that love rockets and love their jobs. Great atmosphere and culture that you have...” -- Eddie Padron | |

We're looking for someone to write a definitive guide to selecting igniters, controllers and batteries for rockets. We'd love to have a newsletter article on that topic, because we get lots of inquiries about it. Is that you? Do you know how many e-matches can be set off in a cluster by a 3.7v 400 mAh battery? See our Newsletter Guidelines on how to submit an article on this topic and get paid up to $350 for your time.

| I'm now actively seeking writers for articles to appear in this newsletter. And I want unique and cutting-edge articles because that is what you want to read, right? I realize this, so to get articles from outside writers that have the same level of quality, I'm going to have to pay a lot of cash to make it worth it for them. So I've come up with a compensation package where I'll pay up to $350 for good how-to articles. Are you a writer, and does that interest you? That is a lot of cash! Far more than you'll get by writing for other magazines. And with over 23,000 worldwide subscribers, if you write for the Peak-of-Flight Newsletter, you'll gain a lot of notoriety. Writing for the Peak-of-Flight Newsletter is a great way to show off your rocketry projects and your technical expertise, at the same time as helping out other rocketeers. Imagine how great you'll feel knowing that you made a difference to the hobby. If you're interested in writing, see the guidelines on our site. | |
